Contribution and Developer Practices

• Please read our best practices and the community guidelines in our Dev Docs.

Setup and Configuration:

Install Android Studio

Install GitHub Desktop

RoboTutor uses a large volume of external assets at runtime. To successfully run RoboTutor you must first install these assets on your target device: English. Swahili. Once you have cloned and run the associated tools to push the data assets to your device you can proceed with building RoboTutor.

Building RoboTutor:

1. Clone RoboTutor to your computer using Git/GitHub

2. Run the setup script ./setup.sh

3. Import the RoboTutor project into Android Studio.

4. You may need to install different versions of the build tools and android SDKs.

5. There are a number of build variants you can select to generate versions that support static language selections and also vesions that permit dynamic language selection at runtime. In order to generate any flavor that depends on the key signature, you must generate your own keystore (see next steps). Note that the version used in the XPrize code drop 1 submission usees flavor release_sw, which depends on a signed APK.

6. If you do not already have one, follow the steps for Android Studio (https://stackoverflow.com/a/30254012) (for (https://stackoverflow.com/questions/3997748/how-can-i-create-a-keystore)) to generate a keystore. Sample command:

keytool -genkeypair -dname "cn=Mark Jones, ou=JavaSoft, o=Sun, c=US" -alias business -keypass kpi135 -keystore /working/android.keystore -storepass ab987c -validity 20000

• dname is a unique identifier for the application in the .keystore

  • cn the full name of the person or organization that generates the .keystore
  • ou Organizational Unit that creates the project, its a subdivision of the Organization that creates it. Ex. android.google.com
  • o Organization owner of the whole project. Its a higher scope than ou. Ex.: google.com
  • c The country short code. Ex: For United States is "US"

• alias Identifier of the app as an single entity inside the .keystore (it can have many)

• keypass Password for protecting that specific alias.

• keystore Path where the .keystore file shall be created (the standard extension is actually .ks)

• storepass Password for protecting the whole .keystore content.

• validity Amount of days the app will be valid with this .keystore

6. Add a file named "keystore.properties" to your root project directory, and give it the following contents. The values should be based on the values you used to generate the keystore.

storePassword=<your_store_password>
keyPassword=<your_key_password>
keyAlias=<your_key_alias>
storeFile=<path_to_location_of_keystore>

7. Use Android Studio or gradlew to generate a signed APK with the flavor release_sw. This will generate the file robotutor.release_sw.1.8.8.1.apk. This APK should be transferred to the apk in your local SystemBuild directory.
