kotlinx-coroutines-play-services

Integration with Google Play Services Tasks API.

Extension functions:

NameDescription
Task.asDeferredConverts a Task into a Deferred
Task.awaitAwaits for completion of the Task (cancellable)
Deferred.asTaskConverts 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
