Describe the bug

When calling RxAmplify.Storage.list(path) on an Android emulator with SDK 35, it crashes with this exception:

Additional information and screenshots

Since there's no current way to migrate a 1.x project to 2.x, we need a solution for the 1.x library that works with Android SDK 35.

Suggested Solution

Luckily the fix is pretty simple: in com.amplifyframework.storage.s3.service.AmplifyTransferService$Companion.startForeground(), make sure you call startForeground(NOTIFICATION_ID, notification, ServiceInfo.FOREGROUND_SERVICE_TYPE_DATA_SYNC) instead (notice specifying the ServiceInfo.FOREGROUND_SERVICE_TYPE_DATA_SYNC type explicitly).

You may also need to add the permission to the manifest:

    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE_DATA_SYNC"/>

and add the type to your service manifest declaration:

    <application>
        <service
            android:name="com.amplifyframework.storage.s3.service.AmplifyTransferService"
            android:foregroundServiceType="dataSync"
            tools:node="merge" />

Hi @odbol.

Amplify v1 is no longer maintained, so we will not fix this issue and strongly recommend you upgrade to V2.

The docs you linked are for upgrading the Amplify backend (server-side) from Gen1 to Gen2. That is not necessary to move to Amplify v2 - Amplify v2 works with both Gen1 and Gen2 backends.

The migration process for Amplify Android from v1 to v2 is fairly straightforward, there are only a handful of code changes that might be necessary. Please see the migration guide for details.
