-Images, layout descriptions, binary blobs and string dictionaries can be included
-in your application as resource files. Various Android APIs are designed to
-operate on the resource IDs instead of dealing with images, strings or binary blobs
-directly.
-
-For example, a sample Android app that contains a user interface layout (main.xml),
-an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png)
-would keep its resources in the "Resources" directory of the application:
-
-Resources/
- drawable-hdpi/
- icon.png
-
- drawable-ldpi/
- icon.png
-
- drawable-mdpi/
- icon.png
-
- layout/
- main.xml
-
- values/
- strings.xml
-
-In order to get the build system to recognize Android resources, set the build action to
-"AndroidResource". The native Android APIs do not operate directly with filenames, but
-instead operate on resource IDs. When you compile an Android application that uses resources,
-the build system will package the resources for distribution and generate a class called
-"Resource" that contains the tokens for each one of the resources included. For example,
-for the above Resources layout, this is what the Resource class would expose:
-
-public class Resource {
- public class drawable {
- public const int icon = 0x123;
- }
-
- public class layout {
- public const int main = 0x456;
- }
-
- public class strings {
- public const int first_string = 0xabc;
- public const int second_string = 0xbcd;
- }
-}
-
-You would then use R.drawable.icon to reference the drawable/icon.png file, or Resource.layout.main
-to reference the layout/main.xml file, or Resource.strings.first_string to reference the first
-string in the dictionary file values/strings.xml.

-# Viewshed for camera
-
-Analyze the viewshed for a camera. A viewshed shows the visible and obstructed areas from an observer's vantage point.
-
-
-
-## Use case
-
-A viewshed analysis is a type of visual analysis you can perform on a scene. The viewshed aims to answer the question 'What can I see from a given location?'. The output is an overlay with two different colors - one representing the visible areas (green) and the other representing the obstructed areas (red).
-
-## How to use the sample
-
-The sample will start with a viewshed created from the initial camera location, so only the visible (green) portion of the viewshed will be visible. Move around the scene to see the obstructed (red) portions. Tap the button to update the viewshed to the current camera position.
-
-## How it works
-
-1. Create a `LocationViewshed`, passing in a `Camera` and a min/max distance.
-2. Update the viewshed using `viewshed.UpdateFromCamera()`.
-
-## Relevant API
-
-* AnalysisOverlay
-* Scene
-* IntegratedMeshLayer
-* ArcGISTiledElevationSource
-* Camera
-* LocationViewshed
-* SceneView
-
-## About the data
-
-The scene shows an integrated mesh layer of [Girona, Spain](https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/Girona_Spain/SceneServer) with the [World Elevation source image service](https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer) both hosted on ArcGIS Online.

-# Collect data in AR
-
-Tap on real-world objects to collect data.
-
-
-
-## Use case
-
-You can use AR to quickly photograph an object and automatically determine the object's real-world location, facilitating a more efficient data collection workflow. For example, you could quickly catalog trees in a park, while maintaining visual context of which trees have been recorded - no need for spray paint or tape.
-
-## How to use the sample
-
-Before you start, go through the on-screen calibration process to ensure accurate positioning of recorded features.
-
-When you tap, an orange diamond will appear at the tapped location. You can move around to visually verify that the tapped point is in the correct physical location. When you're satisfied, tap the '+' button to record the feature. An image from the camera feed will automatically be attached to the recorded feature.
-
-> ⚠ **WARNING**: collection of photos is completely automatic; consider your surroundings when adding features.
-
-## How it works
-
-1. Create an `ARSceneView`. Set the atmosphere effect to `None` and the space effect to `None`. Create and show a scene in the scene view.
-2. Load the feature service and display it with a feature layer.
-3. Create and add the elevation surface to the scene.
-4. Create a graphics overlay for planning the location of features to add. Configure the graphics overlay with a renderer and add the graphics overlay to the scene view.
-5. When the user taps the screen, use `ARSceneView.ARScreenToLocation` to find the real-world location of the tapped object using ARKit/ARCore plane detection.
-6. Add a graphic to the graphics overlay preview where the feature will be placed and allow the user to visually verify the placement.
-7. When the user presses the button, take the current AR frame from `ARSceneView.ArSceneView.ArFrame.AcquireCameraImage()`. Rotate the image appropriately and convert it to a JPEG for efficient storage.
-8. Prompt the user for a tree health value, then create the feature. Upon successful creation of the feature, use `feature.AddAttachment` to add the image.
-
-## Relevant API
-
-* ARSceneView
-* GraphicsOverlay
-* SceneView
-* Surface
-
-## About the data
-
-The sample uses a publicly-editable sample [tree survey feature service](https://arcgisruntime.maps.arcgis.com/home/item.html?id=8feb9ea6a27f48b58b3faf04e0e303ed). You can use AR to quickly record the location and health of a tree while seamlessly capturing a photo.
-
-## Additional information
-
-This sample requires a device that is compatible with ARKit 1 on iOS or ARCore 1.8 on Android.
-
-There are two main approaches for identifying the physical location of tapped point:
-
-* **ARSceneView.ARScreenToLocation** - uses plane detection provided by ARKit/ARCore to determine where _in the real world_ the tapped point is.
-* **SceneView.ScreenToLocation** - determines where the tapped point is _in the virtual scene_. This is problematic when the opacity is set to 0 and you can't see where on the scene that is. Real-world objects aren't accounted for by the scene view's calculation to find the tapped location; for example tapping on a tree might result in a point on the basemap many meters away behind the tree.
-
-This sample only uses the `ARScreenToLocation` approach, as it is the only way to get accurate positions for features not directly on the ground in real-scale AR.
-
-Note that unlike other scene samples, a basemap isn't shown most of the time, because the real world provides the context. Only while calibrating is the basemap displayed at 50% opacity, to give the user a visual reference to compare to.
-
-**Real-scale AR** is one of three main patterns for working with geographic information in augmented reality. See [Augmented reality](https://developers.arcgis.com/net/scenes-3d/display-scenes-in-augmented-reality/) in the guide for more information.
-
-See the 'Edit feature attachments' sample for more specific information about the attachment editing workflow.
-
-This sample uses a combination of two location data source modes: continuous update and one-time update, presented as 'roaming' and 'local' calibration modes in the app. The error in the position provided by ARKit/ARCore increases as you move further from the origin, resulting in a poor experience when you move more than a few meters away. The location provided by GPS is more useful over large areas, but not good enough for a convincing AR experience on a small scale. With this sample, you can use 'roaming' mode to maintain good enough accuracy for basic context while navigating a large area. When you want to see a more precise visualization, you can switch to 'local' (ARKit/ARCore-only) mode and manually calibrate for best results.

-# Display scenes in tabletop AR
-
-Use augmented reality (AR) to pin a scene to a table or desk for easy exploration.
-
-
-
-## Use case
-
-Tabletop scenes allow you to use your device to interact with scenes as if they are 3D-printed model models sitting on your desk. You could use this to virtually explore a proposed development without needing to create a physical model.
-
-## How to use the sample
-
-You'll see a feed from the camera when you open the sample. Tap on any flat, horizontal surface (like a desk or table) to place the scene. With the scene placed, you can move the camera around the scene to explore. You can also pan and zoom with touch to adjust the position of the scene.
-
-## How it works
-
-1. Create an `ARSceneView` and add it to the view.
- * Note: this sample uses content in the WGS 84 geographic tiling scheme, rather than the web mercator tiling scheme. Once a scene has been displayed, the scene view cannot display another scene with a non-matching tiling scheme. To avoid that, the sample starts by showing a blank scene with an invisible base surface. Touch events will not be raised for the scene view unless a scene is displayed.
-2. Wait for plane detection using `arView.PlanesDetectedChanged` before allowing the user to tap to place the scene.
-3. Wait for the user to tap the view, then use `arView.SetInitialTransforamtion(tappedPoint)` to set the initial transformation, which allows you to place the scene. This method uses ARKit's built-in plane detection.
-4. If the call to `SetInitialTransformation` returns `true`, proceed to load the scene and display it.
-5. To enable looking at the scene from below, set `scene.BaseSurface.NavigationConstraint` to `0`.
-6. Set the origin camera to the point in the scene where it should be anchored to the real-world surface you tapped. Typically that is the point at the center of the scene, with the altitude of the lowest point in the scene.
-7. Set `arView.TranslationFactor` such that the user can view the entire scene by moving the device around it. The translation factor defines how far the virtual camera moves when the physical camera moves.
- * A good formula for determining translation factor to use in a tabletop map experience is **translationFactor = sceneWidth / tableTopWidth**. The scene width is the width/length of the scene content you wish to display in meters. The tabletop width is the length of the area on the physical surface that you want the scene content to fill. For simplicity, the sample assumes a scene width of 800 meters and physical size of 1 meter.
-
-## Relevant API
-
-* ARSceneView
-* Surface
-
-## Offline data
-
-This sample uses offline data, available as an [item on ArcGIS Online](https://www.arcgis.com/home/item.html?id=7dd2f97bb007466ea939160d0de96a9d).
-
-## About the data
-
-This sample uses the [Philadelphia Mobile Scene Package](https://www.arcgis.com/home/item.html?id=7dd2f97bb007466ea939160d0de96a9d). It was chosen because it is a compact scene ideal for tabletop use. Note that tabletop mapping experiences work best with small, focused scenes. The small, focused area with basemap tiles defines a clear boundary for the scene.
-
-## Additional information
-
-**Tabletop AR** is one of three main patterns for working with geographic information in augmented reality. See [Display scenes in augmented reality](https://developers.arcgis.com/net/scenes-3d/display-scenes-in-augmented-reality/) in the guide for more information.
-
-This sample uses the ArcGIS Runtime Toolkit. See [Display scenes in augmented reality](https://developers.arcgis.com/net/scenes-3d/display-scenes-in-augmented-reality/) in the guide to learn about the toolkit and how to add it to your app.

-# Explore scenes in flyover AR
-
-Use augmented reality (AR) to quickly explore a scene more naturally than you could with a touch or mouse interface.
-
-
-
-## Use case
-
-You can use AR to drop into an area and visualize information, like a proposed development or a historical model of a city. You could use flyover AR to explore a city by walking through it virtually.
-
-## How to use the sample
-
-When you open the sample, you'll be viewing the scene from above. You can walk around, using your device as a window into the scene. Try moving vertically to get closer to the ground. Touch gestures which
-
-## How it works
-
-1. Create the `ARSceneView` and add it to the view.
-2. Create the scene, add content, then display it.
-3. When the content you want to view loads, get its center point and use that to create the origin camera for the AR view. Note that the altitude should be set so that all scene content is visible. For a city, a good value might be a bit higher than the tallest building. The sample uses 600 meters in the absence of tall buildings in the sample data.
-4. Set the translation factor so that you can move through the scene easily. With a translation factor of 800, you will move 800 feet in the scene for every foot you move the physical device.
-5. Set the space effect to `Stars` and atmosphere effect to `Realistic` to create an immersive experience.

-# Navigate in AR
-
-Use a route displayed in the real world to navigate.
-
-
-
-## Use case
-
-It can be hard to navigate using 2D maps in unfamiliar environments. You can use real-scale AR to show a route overlaid on the real-world for easier navigation.
-
-## How to use the sample
-
-The sample opens with a map centered on the current location. Tap the map to add an origin and a destination; the route will be shown as a line. When ready, click 'Confirm' to start the AR navigation. Calibrate the heading before starting to navigate. When you start, route instructions will be displayed and spoken. As you proceed through the route, new directions will be provided until you arrive.
-
-## How it works
-
-1. The map page is used to plan the route before starting the AR experience. See the *Find a route* and *Offline routing* samples for a more focused demonstration of that workflow.
-2. Pass the resulting `RouteResult` to the view used for the AR portion of the navigation experience.
-3. Start ARKit tracking with continuous location updates when the AR view is shown.
- * The sample uses a custom location data source that allows you to apply an altitude offset. The altitude reported by the system location data source is often off by tens of meters.
-4. Get the route geometry from the first route in the `RouteResult`. Display the route in an overlay configured to show graphics offset from the surface with `Relative` surface placement mode.
-5. Add the route geometry to a graphics overlay and add a renderer to the graphics overlay. This sample uses a `MultilayerPolylineSymbol` with a `SolidStrokeSymbolLayer` to visualize a tube along the route line.
-6. Create a calibration view. This sample uses a slider to manipulate the heading (direction you are facing). Because of limitations in on-device compasses, calibration is often necessary; small errors in heading cause big problems with the placement of scene content in the world.
- * Note that while this sample implemented a slider, there are many possible strategies for implementing heading calibration.
- * While calibrating, the basemap is shown at 50% opacity, to allow you to compare the basemap imagery with what is seen by the camera. While this works in some environments, it won't work indoors, in forested areas, or if the ground truth has changed since the basemap imagery was updated. Alternative scenarios can involve orienting relative to landmarks (for example, stage sets at a concert) or starting at a known orientation by lining up with a static image.
- * The slider in the sample implements a 'joystick' interaction; the heading is adjusted faster the further you move from the center of the slider. There are many possible slider interactions you could choose to implement.
-7. When the user starts navigating, create a `RouteTracker`, providing a `RouteResult` and the index of the route you want to use; this sample always picks the first returned result.
-8. Create a location data source and listen for location change events. When the location changes, call `routeTracker.TrackLocation` with the updated location.
-9. Keep the calibration view accessible throughout the navigation experience. As the user walks, small heading errors may become more noticeable and require recalibration.

-* GeometryEngine
-* LocationDataSource
-* RouteResult
-* RouteTask

-* Surface
-
-## About the data
-
-This sample uses Esri's [world elevation service](https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer) to ensure that route lines are placed appropriately in the 3D space. It uses the [world routing service](https://www.arcgis.com/home/item.html?id=1feb41652c5c4bd2ba5c60df2b4ea2c4) to calculate routes. The world routing service requires authentication and does consume ArcGIS Online credits.
-
-## Additional information
-
-This sample requires a device that is compatible with ARCore.
-
-Unlike other scene samples, there's no need for a basemap while navigating, because context is provided by the camera feed showing the real environment. The base surface's opacity is set to zero to prevent it from interfering with the AR experience. During calibration, the basemap is shown at 50% opacity to help the user verify that they have calibrated properly.
-
-A digital elevation model is used to ensure that the displayed route is positioned appropriately relative to the terrain of the route. If you don't want to display the route line floating, you could show the line draped on the surface instead.
-
-**Real-scale AR** is one of three main patterns for working with geographic information in augmented reality. See [Display scenes in augmented reality](https://developers.arcgis.com/net/scenes-3d/display-scenes-in-augmented-reality/) in the guide for more information.
-
-Because most navigation scenarios involve traveling beyond the accurate range for ARKit positioning, this sample relies on **continuous location updates** from the location data source. Because the origin camera is constantly being reset by the location data source, the sample doesn't allow the user to pan to calibrate or adjust the altitude with a slider. The location data source doesn't provide a heading, so it isn't overwritten when the location refreshes.

-# View hidden infrastructure in AR
-
-Visualize hidden infrastructure in its real-world location using augmented reality.
-
-
-
-## Use case
-
-You can use AR to 'x-ray' the ground to see pipes, wiring, or other infrastructure that isn't otherwise visible. You could use this feature to trace the flow of water through a building to help identify the source of a leak.
-
-## How to use the sample
-
-When you open the sample, you'll see a map centered on your current location. Use the tools to draw pipes around your location. An elevation surface will be queried to place the drawn infrastructure above or below ground. When you're ready, use the button to view the infrastructure you drew in AR.
-
-There are two calibration modes in the sample: roaming and local. In roaming calibration mode, your position is updated automatically from the location data source every second. Because of that, you can only adjust heading, not position or elevation. This mode is best when working in a large area, where you would travel beyond the useful range of ARKit/ARCore.
-
-When you're ready to take a more precise look at the infrastructure, switch to local calibration mode. In local calibration mode, you can make fine adjustments to location, altitude, and heading to ensure the content is exactly where it should be.
-
-## How it works
-
-1. See the 'Sketch on map' sample to learn how to use the sketch editor for creating graphics.
-2. When you start the AR visualization experience, create and show the `ARSceneView`.
-3. Access the `Scene` property of the AR View and set the space effect `SpaceEffect.None` and the atmosphere effect to `AtmosphereEffect.None`.
-4. Create an elevation source and add it to the scene's base surface. Set the navigation constraint to `NavigationConstraint.None` to allow going underground if needed.
-5. Configure a graphics overlay and renderer for showing the drawn pipes. This sample uses a `SolidStrokeSymbolLayer` with a `MultilayerPolylineSymbol` to draw the pipes as tubes. Add the drawn pipes to the overlay.
-6. Configure the calibration experience.
- * When in roaming (continuous location update) mode, only heading calibration should be enabled. In continuous update mode, the user's calibration is overwritten by sensor-based values every second.
- * When in local mode, the user needs to be able to adjust the heading, altitude, and position; position adjustment is achieved by panning.
- * This sample uses a basemap as a reference during calibration; consider how you will support your user's calibration efforts. A basemap-oriented approach won't work indoors or in areas without readily visible, unchanging features like roads.
-
-## Relevant API
-
-* ARSceneView
-* GraphicsOverlay
-* MultilayerPolylineSymbol
-* SketchEditor
-* SolidStrokeSymbolLayer
-* Surface
-
-## About the data
-
-This sample uses Esri's [world elevation service](https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer) to ensure that the infrastructure you create is accurately placed beneath the ground.
-
-Real-scale AR relies on having data in real-world locations near the user. It isn't practical to provide pre-made data like other Runtime samples, so you must draw your own nearby sample 'infrastructure' prior to starting the AR experience.
-
-## Additional information
-
-This sample requires a device that is compatible with ARKit 1 on iOS or ARCore 1.8 on Android.
-
-Note that unlike other scene samples, a basemap isn't shown most of the time, because the real world provides the context. Only while calibrating is the basemap displayed at 50% opacity, to give the user a visual reference to compare to.
-
-You may notice that pipes you draw underground appear to float more than you would expect. That floating is a normal result of the parallax effect that looks unnatural because you're not used to being able to see underground/obscured objects. Compare the behavior of underground pipes with equivalent pipes drawn above the surface - the behavior is the same, but probably feels more natural above ground because you see similar scenes day-to-day (e.g. utility wires).
-
-**Real-scale AR** is one of three main patterns for working with geographic information in augmented reality. See [Agumented reality](https://developers.arcgis.com/net/scenes-3d/display-scenes-in-augmented-reality/) in the guide for more information.
-
-This sample uses a combination of two location data source modes: continuous update and one-time update, presented as 'roaming' and 'local' calibration modes in the app. The error in the position provided by ARKit/ARCore increases as you move further from the origin, resulting in a poor experience when you move more than a few meters away. The location provided by GPS is more useful over large areas, but not good enough for a convincing AR experience on a small scale. With this sample, you can use 'roaming' mode to maintain good enough accuracy for basic context while navigating a large area. When you want to see a more precise visualization, you can switch to 'local' (ARKit/ARCore-only) mode and manually calibrate for best results.

-
-## How to use the sample
-
-Tap on a location on the map to add a feature at that location.
-
-## How it works
-
-A `Feature` instance is added to a `ServiceFeatureTable` which then pushes that new feature to the server.

-1. Create a `ServiceFeatureTable` object from a URL.
-2. Create a `FeatureLayer` object from the service feature table.
-3. Select features from the feature layer via `FeatureLayer.SelectFeatures()`.
-4. Remove the selected features from the service feature table using `ServiceFeatureTable.DeleteFeatureAsync()`.
-5. Update the table on the server using `ServiceFeatureTable.ApplyEditsAsync()`.

-# Edit and sync features
-
-Synchronize offline edits with a feature service.
-
-
-
-## Use case
-
-A survey worker who works in an area without an internet connection could take a geodatabase of survey features offline at their office, make edits and add new features to the offline geodatabase in the field, and sync the updates with the online feature service after returning to the office.
-
-## How to use the sample
-
-Pan and zoom to position the red rectangle around the area you want to take offline. Tap "Generate geodatabase" to take the area offline. When complete, the map will update to only show the offline area. To edit features, tap to select a feature, and tap again anywhere else on the map to move the selected feature to the clicked location. To sync the edits with the feature service, tap the "Sync geodatabase" button.
-
-## How it works
-
-1. Create a `GeodatabaseSyncTask` from a URL to a feature service.
-2. Use `createDefaultGenerateGeodatabaseParametersAsync()` on the geodatabase sync task to create `GenerateGeodatabaseParameters`, passing in an `Envelope` extent as the parameter.
-3. Create a `GenerateGeodatabaseJob` from the `GeodatabaseSyncTask` using `generateGeodatabaseAsync(...)`, passing in the parameters and a path to where the geodatabase should be downloaded locally.
-4. Start the job and get the result `Geodatabase`.
-5. Load the geodatabase and get its feature tables. Create feature layers from the feature tables and add them to the map's operational layers collection.
-6. Create `SyncGeodatabaseParameters` and set the sync direction.
-7. Create a `SyncGeodatabaseJob` from `GeodatabaseSyncTask` using `.syncGeodatabaseAsync(...)` passing in the parameters and geodatabase as arguments.
-8. Start the sync job to synchronize the edits.

-## Offline data
-
-This sample uses a [San Francisco offline basemap tile package](https://www.arcgis.com/home/item.html?id=e4a398afe9a945f3b0f4dca1e4faccb5).
-
-## About the data
-
-The basemap uses an offline tile package of San Francisco. The online feature service has features with wildfire information.

-# Edit features with feature-linked annotation
-
-Edit feature attributes which are linked to annotation through an expression.
-
-
-
-## Use case
-
-Annotation is useful for displaying text that you don't want to move or resize when the map is panned or zoomed (unlike labels which will move and resize). Feature-linked annotation will update when a feature attribute referenced by the annotation expression is also updated. Additionally, the position of the annotation will transform to match any transformation to the linked feature's geometry.
-
-## How to use the sample
-
-Pan and zoom the map to see that the text on the map is annotation, not labels. Tap one of the address points to update the house number (AD_ADDRESS) and street name (ST_STR_NAM). Tap one of the dashed parcel polylines and tap another location to change its geometry. NOTE: Selection is only enabled for points and straight (single segment) polylines.
-
-The feature-linked annotation will update accordingly.
-
-## How it works
-
-1. Load the geodatabase. NOTE: Read/write geodatabases should normally come from a `GeodatabaseSyncTask`, but this has been omitted here. That functionality is covered in the sample *Generate geodatabase*.
-2. Create `FeatureLayer`s from geodatabase feature tables found in the geodatabase with `geodatabase.GeodatabaseFeatureTable`.
-3. Create `AnnotationLayer`s from geodatabase feature tables found in the geodatabase with `geodatabase.GeodatabaseAnnotationTable`.
-4. Add the `FeatureLayer`s and `AnnotationLayer`s to the map's operational layers.
-5. Use a `GeoViewTapped` event handler to listen for clicks on the map to either select address points or parcel polyline features. NOTE: Selection is only enabled for points and straight (single segment) polylines.
- * For the address points, a dialog is opened to allow editing of the address number (AD_ADDRESS) and street name (ST_STR_NAM) attributes.
- * For the parcel lines, a second tap will change one of the polyline's vertices.
-
-Both expressions were defined by the data author in ArcGIS Pro using [the Arcade expression language](https://developers.arcgis.com/arcade/).
-
-## Relevant API
-
-* AnnotationLayer
-* Feature
-* FeatureLayer
-* Geodatabase
-
-## Offline data
-
-This sample downloads the following items from ArcGIS Online automatically:
-
-* [loudoun_anno geodatabase](https://www.arcgis.com/home/item.html?id=74c0c9fa80f4498c9739cc42531e9948)
-
-## About the data
-
-This sample uses data derived from the [Loudoun GeoHub](https://geohub-loudoungis.opendata.arcgis.com/).
-
-The annotation linked to the point data in this sample is defined by arcade expression `$feature.AD_ADDRESS + " " + $feature.ST_STR_NAM`. The annotation linked to the parcel polyline data is defined by `Round(Length(Geometry($feature), 'feet'), 2)`.

-# Feature layer (geodatabase)
-
-Display features from a local geodatabase.
-
-
-
-## Use case
-
-Accessing data from a local geodatabase is useful when working in an environment that has an inconsistent internet connection or that does not have an internet connection at all. For example, a department of transportation field worker might source map data from a local geodatabase when conducting signage inspections in rural areas with poor network coverage.
-
-## How it works
-
-1. Create a geodatabase using the provided local resource, `new Geodatabase(geodatabaseResourceUrl)`.
-2. Wait for geodatabase to load.
-3. Get the 'Trailheads' `GeodatabaseFeatureTable` from the geodatabase, `Geodatabase.GeodatabaseFeatureTable(tableName)`.
-4. Create feature layer using the table from above, `new FeatureLayer(geodatabaseFeatureTable)`.
-5. Add feature layer to `Map` with `Map.OperationalLayers.Add(featureLayer)`.
-

-* FeatureLayer
-* Geodatabase
-* GeodatabaseFeatureTable

-## Offline data

-* [Los Angeles Vector Tile Package](https://www.arcgis.com/home/item.html?id=d9f8ce6f6ac84b90a665a861d71a5d0a) - Streets Vector Tile Package (vtpk) for the City of Los Angeles.
-* [Los Angeles Trailheads](https://www.arcgis.com/home/item.html?id=2b0f9e17105847809dfeb04e3cad69e0) - Mobile geodatabase containing LA trailhead locations
-
-## Additional information
-
-One of the ArcGIS Runtime data set types that can be accessed via the local storage of the device (i.e. hard drive, flash drive, micro SD card, USB stick, etc.) is a mobile geodatabase. A mobile geodatabase can be provisioned for use in an ArcGIS Runtime application by ArcMap. The following provide some helpful tips on how to create a mobile geodatabase file:
-
-In ArcMap, choose File > Share As > ArcGIS Runtime Content from the menu items to create the .geodatabase file (see the document: http://desktop.arcgis.com/en/arcmap/latest/map/working-with-arcmap/creating-arcgis-runtime-content.htm).
-
-Note: You could also use the 'Services Pattern' and access the `Geodatabase` class via a Feature Service served up via ArcGIS Online or ArcGIS Enterprise. Instead of using the `Geodatabase` class to access the .geodatabase file on disk, you would use `GeodatabaseSyncTask` to point to a Uri instead.

-# Feature layer query
-
-Find features in a feature table which match an SQL query.
-
-
-
-## Use case
-
-Query expressions can be used in ArcGIS to select a subset of features from a feature table. This is most useful in large or complicated data sets. A possible use case might be on a feature table marking the location of street furniture through a city. A user may wish to query by a TYPE column to return "benches". In this sample, we query a U.S. state by STATE_NAME from a feature table containing all U.S. states.
-
-## How to use the sample
-
-Input the name of a U.S. state into the text field. When you tap the button, a query is performed and the matching features are highlighted or an error is returned.
-
-## How it works
-
-1. Create a `ServiceFeatureTable` using the URL of a feature service.
-2. Create a `QueryParameters` with a where clause specified using the `WhereClause` property.
-3. Perform the query using `QueryFeaturesAsync(query)` on the service feature table.
-4. When complete, the query will return a `FeatureQueryResult` which can be iterated over to get the matching features.
-
-## Relevant API
-
-* FeatureLayer
-* FeatureQueryResult
-* QueryParameters
-* ServiceFeatureTable
-
-## About the data
-
-This sample uses U.S. State polygon features from the [USA 2016 Daytime Population](https://www.arcgis.com/home/item.html?id=f01f0eda766344e29f42031e7bfb7d04) feature service.

-# Generate geodatabase
-
-Generate a local geodatabase from an online feature service.
-
-
-
-## Use case
-
-Generating geodatabases is the first step toward taking a feature service offline. It allows you to save features locally for offline display.
-
-## How to use the sample
-
-Zoom to any extent. Then tap the generate button to generate a geodatabase of features from a feature service filtered to the current extent. A red outline will show the extent used. The job's progress is shown while the geodatabase is generated.
-
-## How it works
-
-1. Create a `GeodatabaseSyncTask` with the URL of the feature service and load it.
-2. Create `GenerateGeodatabaseParameters` specifying the extent and whether to include attachments.
-3. Create a `GenerateGeodatabaseJob` with `geodatabaseSyncTask.GenerateGeodatabaseAsync(parameters, downloadPath)`. Start the job with `job.Start()`.
-4. When the job is done, `job.GetResultAsync()` will return the geodatabase. Inside the geodatabase are feature tables which can be used to add feature layers to the map.
-5. Call `syncTask.UnregisterGeodatabaseAsync(geodatabase)` after generation when you're not planning on syncing changes to the service.

-# Format coordinates
-
-Format coordinates in a variety of common notations.
-
-
-
-## Use case
-
-The coordinate formatter can format a map location in WGS84 in a number of common coordinate notations. Parsing one of these formats to a location is also supported. Formats include decimal degrees; degrees, minutes, seconds; Universal Transverse Mercator (UTM), and United States National Grid (USNG).
-
-## How to use the sample
-
-Tap on the map to see a callout with the clicked location's coordinate formatted in 4 different ways. You can also put a coordinate string in any of these formats in the text field. Hit Enter and the coordinate string will be parsed to a map location which the callout will move to.
-
-## How it works
-
-1. Get or create a `MapPoint` with a spatial reference.
-2. Use one of the static "to" methods on `CoordinateFormatter` such as `CoordinateFormatter.ToLatitudeLongitude(point, CoordinateFormatter.LatitudeLongitudeFormat.DecimalDegrees, 4)` to get the formatted string.
-3. To go from a formatted string to a `Point`, use one of the "from" static methods like `CoordinateFormatter.FromUtm(coordinateString, map.SpatialReference, CoordinateFormatter.UtmConversionMode.NorthSouthIndicators)`.
-
-## Relevant API
-
-* CoordinateFormatter
-* CoordinateFormatter.LatitudeLongitudeFormat
-* CoordinateFormatter.UtmConversionMode
-
-## Tags
-
-convert, coordinate, decimal degrees, degree minutes seconds, format, latitude, longitude, USNG, UTM

-# List transformations by suitability
-
-Get a list of suitable transformations for projecting a geometry between two spatial references with different horizontal datums.
-
-
-
-## Use case
-
-Transformations (sometimes known as datum or geographic transformations) are used when projecting data from one spatial reference to another when there is a difference in the underlying datum of the spatial references. Transformations can be mathematically defined by specific equations (equation-based transformations), or may rely on external supporting files (grid-based transformations). Choosing the most appropriate transformation for a situation can ensure the best possible accuracy for this operation. Some users familiar with transformations may wish to control which transformation is used in an operation.
-
-## How to use the sample
-
-Select a transformation from the list to see the result of projecting the point from EPSG:27700 to EPSG:3857 using that transformation. The result is shown as a red cross; you can visually compare the original blue point with the projected red cross.
-
-Select 'Consider current extent' to limit the transformations that are appropriate for the current extent.
-
-If the selected transformation is not usable (has missing grid files) then an error is displayed.
-
-## How it works
-
-1. Pass the input and output spatial references to `TransformationCatalog.GetTransformationsBySuitability` for transformations based on the map's spatial reference OR additionally provide an extent argument to only return transformations suitable to the extent. This returns a list of ranked transformations.
-2. Use one of the `DatumTransformation` objects returned to project the input geometry to the output spatial reference.
-
-## Relevant API
-
-* DatumTransformation
-* GeographicTransformation
-* GeographicTransformationStep
-* GeometryEngine
-* GeometryEngine.Project
-* TransformationCatalog
-
-## Additional information
-
-Some transformations aren't available until transformation data is provided.
-
-This sample uses a `GeographicTransformation`, which extends the `DatumTransformation` class. As of 100.9, ArcGIS Runtime also includes a `HorizontalVerticalTransformation`, which also extends `DatumTransformation`. The `HorizontalVerticalTransformation` class is used to transform coordinates of z-aware geometries between spatial references that have different geographic and/or vertical coordinate systems.
-
-This sample can be used with or without provisioning projection engine data to your device. If you do not provision data, a limited number of transformations will be available.
-
-To download projection engine data to your device:
-1. Log in to the [ArcGIS for Developers site](https://developers.arcgis.com/sign-in/) using your Developer account.
-2. In the Dashboard page, tap '[Download APIs and SDKs](https://developers.arcgis.com/downloads/#pedata)'.
-3. Tap the download button next to `Projection Engine Data` to download projection engine data to your computer.
-4. Unzip the downloaded data on your computer.
-5. Create an `~/ArcGIS/Runtime/Data/PEDataRuntime` directory on your device and copy the files to this directory.
-
-## About the data
-
-The map starts out zoomed into the grounds of the Royal Observatory, Greenwich. The initial point is in the [British National Grid](https://epsg.io/27700) spatial reference, which was created by the United Kingdom Ordnance Survey. The spatial reference after projection is in [web mercator](https://epsg.io/3857).

-# Nearest vertex
-
-Find the closest vertex and coordinate of a geometry to a point.
-
-
-
-## Use case
-
-Determine the shortest distance between a location and the boundary of an area. For example, developers can snap imprecise user clicks to a geometry if the tap is within a certain distance of the geometry.
-
-## How to use the sample
-
-Tap anywhere on the map. An orange cross will show at that location. A blue circle will show the polygon's nearest vertex to the point that was clicked. A red diamond will appear at the coordinate on the geometry that is nearest to the point that was clicked. If clicked inside the geometry, the red and orange markers will overlap. The information box showing distance between the clicked point and the nearest vertex/coordinate will be updated with every new location clicked.
-
-## How it works
-
-1. Get a `Geometry` and a `Point` to check the nearest vertex against.
-2. Call `GeometryEngine.NearestVertex(inputGeometry, point)`.
-3. Use the returned `ProximityResult` to get the `Point` representing the polygon vertex, and to determine the distance between that vertex and the clicked point.
-4. Call `GeometryEngine.NearestCoordinate(inputGeometry, point)`.
-5. Use the returned `ProximityResult` to get the `Point` representing the coordinate on the polygon, and to determine the distance between that coordinate and the clicked point.

-# Project
-
-Project a point from one spatial reference to another.
-
-
-
-## Use case
-
-Being able to project between spatial references is fundamental to a GIS. An example of when you would need to re-project data is if you had data in two different spatial references, but wanted to perform an intersect analysis with the `GeometryEngine.intersect` function. This function takes two geometries as parameters, and both geometries must be in the same spatial reference. If they are not, you could first use `GeometryEngine.project` to convert the geometries so they match.
-
-## How to use the sample
-
-Tap anywhere on the map. A callout will display the clicked location's coordinate in the original (basemap's) spatial reference and in the projected spatial reference.
-
-## How it works
-
-1. Call the static method, `GeometryEngine.Project`, passing in the original `Geometry` and a `SpatialReference` to which it should be projected.
-
-## Relevant API
-
-* GeometryEngine
-* Point
-* SpatialReference
-
-## Additional information
-
-In cases where the the output spatial reference uses a different geographic coordinate system than that of the input spatial reference, see the GeometryEngine.project method that additionally takes in a DatumTransformation parameter.
