Module kotlinx-coroutines-play-services

Integration with Google Play Services Tasks API.

Extension functions:

Name	Description
Task.asDeferred	Converts a Task into a Deferred
Task.await	Awaits for completion of the Task (cancellable)
Deferred.asTask	Converts a deferred value to a Task

Example

Using Firebase APIs becomes simple:

FirebaseAuth.getInstance().signInAnonymously().await()
val snapshot = try {
    FirebaseFirestore.getInstance().document("users/$id").get().await() // Cancellable await
} catch (e: FirebaseFirestoreException) {
    // Handle exception
    return@async
}

// Do stuff

If the Task supports cancellation via passing a CancellationToken, pass the corresponding CancellationTokenSource to asDeferred or await to support bi-directional cancellation:

val cancellationTokenSource = CancellationTokenSource()
val currentLocationTask = fusedLocationProviderClient.getCurrentLocation(PRIORITY_HIGH_ACCURACY, cancellationTokenSource.token)
val currentLocation = currentLocationTask.await(cancellationTokenSource) // cancelling `await` also cancels `currentLocationTask`, and vice versa
