GcmTaskService Example

MyTaskService handles one time and repetitive tasks in the background thread.

Starting Task Service

Call startTaskService() in onCreate and start service in onActivityResult. This way TaskService will only start if a task is scheduled.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (savedInstanceState != null)
        startTaskService();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case REQUEST_GOOGLE_PLAY_SERVICES:
        if (resultCode == Activity.RESULT_OK) {
            Intent i = new Intent(this, TaskService.class);
            startService(i);
        }
        break;
        default:
        super.onActivityResult(requestCode, resultCode, data);
    }
}

private void startTaskService() {
    GoogleApiAvailability api = GoogleApiAvailability.getInstance();
    int isAvailable = api.isGooglePlayServicesAvailable(this);
    if (isAvailable == ConnectionResult.SUCCESS) {
        onActivityResult(REQUEST_GOOGLE_PLAY_SERVICES, Activity.RESULT_OK, null);
    } else if (api.isUserResolvableError(isAvailable) &&
    api.showErrorDialogFragment(this, isAvailable, REQUEST_GOOGLE_PLAY_SERVICES)) {
        // wait for onActivityResult call
        } else {
        Toast.makeText(this, api.getErrorString(isAvailable), Toast.LENGTH_LONG).show();
    }
}
