Example 1 with TaskCompletionSource

use of com.google.android.gms.tasks.TaskCompletionSource in project FirebaseUI-Android by firebase.

the class GoogleApiClientTaskHelper method getConnectedGoogleApiClient.

public Task<GoogleApiClient> getConnectedGoogleApiClient() {
    final TaskCompletionSource<GoogleApiClient> source = new TaskCompletionSource<>();
    if (!mConnectTaskRef.compareAndSet(null, source)) {
        // mConnectTaskRef Task was not null, return Task
        return mConnectTaskRef.get().getTask();
    }
    final GoogleApiClient client = mBuilder.addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {

        @Override
        public void onConnected(@Nullable Bundle bundle) {
            source.setResult(mClientRef.get());
            if (mClientRef.get() != null) {
                mClientRef.get().unregisterConnectionCallbacks(this);
            }
        }

        @Override
        public void onConnectionSuspended(int i) {
        }
    }).addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {

        @Override
        public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
            source.setException(new IOException("Failed to connect GoogleApiClient: " + connectionResult.getErrorMessage()));
            if (mClientRef.get() != null) {
                mClientRef.get().unregisterConnectionFailedListener(this);
            }

                }).addOnSuccessListener(scoutKeys -> scoutIndicesTask.setResult(Pair.create(helper, scoutKeys)));
            }

            @Override
