Example: Communication between Activity and Service using Messaging

Question

I couldn\'t find any examples of how to send messages between an activity and a service, and I have spent far too many hours figuring this out. Here is an example project fo

Answer 1

This is how I implemeted Activity->Service Communication: on my Activity i had

private static class MyResultReciever extends ResultReceiver {
     /**
     * Create a new ResultReceive to receive results.  Your
     * {@link #onReceiveResult} method will be called from the thread running
     * handler if given, or from an arbitrary thread if null.
     *
     * @param handler
     */
     public MyResultReciever(Handler handler) {
         super(handler);
     }

     @Override
     protected void onReceiveResult(int resultCode, Bundle resultData) {
         if (resultCode == 100) {
             //dostuff
         }
     }

And then I used this to start my Service

protected void onCreate(Bundle savedInstanceState) {
MyResultReciever resultReciever = new MyResultReciever(handler);
        service = new Intent(this, MyService.class);
        service.putExtra("receiver", resultReciever);
        startService(service);
}

In my Service i had

public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null)
        resultReceiver = intent.getParcelableExtra("receiver");
    return Service.START_STICKY;
}

Hope this Helps
