Can't See My AsyncTask Start and Service

Question

I wrote some code to start a service from AsyncTask, and I can see on debug mode that the service is started.

The code for starting the service on the background on AsyncTask is as follows,

protected String doInBackground(String... params) {
//starts service number activite
MyResultReceiver resultReceiver = new MyResultReceiver(null);
Intent  intent = new Intent(context, MyService.class);
intent.putExtra("receiver", resultReceiver);
context.startService(intent);

and the serivce is:

    public class MyService extends Service{


    ResultReceiver resultReceiver;


       @Override
     public int onStartCommand(Intent intent, int flags, int startId) {

       //resultReceiver = intent.getParcelableExtra("receiver");


        resultReceiver = intent.getParcelableExtra("receiver");
        Bundle data = new Bundle();
          data.putString("key",getActivityUrl() );
       resultReceiver.send(2, data);

       resultReceiver.send(2,null);
     return START_STICKY;
     }



        @Override
          public IBinder onBind(Intent intent) {
          return null;
             }

     public String getActivityUrl() {
   String str = null;   
       try{

URL url = null;
        try {
            url = new URL("http://www.google.com");
        } catch (MalformedURLException ex) {
            Logger.getLogger(MyService.class.getName()).log(Level.SEVERE, null, ex);
        }

        // Read all the text returned by the server
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

        while ((str = in.readLine()) != null) {
            // str is one line of text; readLine() strips the newline character(s)
        }
                //all is ok

        in.close();

     }       catch (IOException ex) {
        Logger.getLogger(MyService.class.getName()).log(Level.SEVERE, null, ex);
    }finally{ stopSelf();
     }

    //resultReceiver.send(100,null);

    return str;
}

}

Another question: How can I send a String and not only an int with resultReceiver.send?

how can I send string and not only int with resultReceiver.send?

Just create Bundle and put in String.

Bundle data = new Bundle();
data.putString("key", data);
resultReceiver.send(2, someData);

Note: Only for sure, first parameter of send() method imagine resultCode for onReceiveResult method.

why you are using Asynctask and ResultReceiver? AsyncTask has onProgressUpdate method for update your UI also from your code im little confused, dirty written. – Simon Dorociak Jun 29 '12 at 12:19

so when you want to do it with service, dont complicate it with AsyncTask and do your work in Service and send progress via resultreceiver. you need to read some tutorial, i cant teach you basics. your application logic is not good. a recommend to you use IntentService with ResultReceiver. [here](http://stackoverflow.com/questions/11137754/comunication-between-service-web-and-activity-back-and-forth-in-android/11138045#11138045) in my another answer is snippet of code how to use IntentService with ResultReceiver. – Simon Dorociak Jun 29 '12 at 12:23
I will take a look but any idea why me service not starting? I edit full code of my service – Vitaly Menchikovsky Jun 29 '12 at 12:47
just i wrote, bad application logic. – Simon Dorociak Jun 29 '12 at 12:48
I wrote as you said but still the same thing this post here:http://stackoverflow.com/questions/11263138/service-not-starting-from-asynctask – Vitaly Menchikovsky Jun 29 '12 at 14:52
did you check link that i meant? – Simon Dorociak Jun 29 '12 at 14:55
yes as you can see I did like you said on you link you can see it on my link before. I am getting the same result. – Vitaly Menchikovsky Jun 29 '12 at 15:17
my problem with this line serviceIntent.putExtra("receiver", new tools.DownloadReceiver(new Handler())); if I remove this line I can see that on debug its create a service but when I did this line its creashed. why is that? – Vitaly Menchikovsky Jun 29 '12 at 15:31
putExtra("receiver", new DownloadReceiver(new Handler())); you should have resultreceiver as inner class in your Main Activity class. – Simon Dorociak Jun 29 '12 at 15:32
did a class on my asy task private class DownloadReceiver extends ResultReceiver{ public DownloadReceiver(Handler handler) { super(handler); } @Override protected void onReceiveResult(int resultCode, Bundle resultData) { super.onReceiveResult(resultCode, resultData); // if (resultCode == DownloadService.UPDATE_PROGRESS) { int progress = resultData.getInt("progress");}} – Vitaly Menchikovsky Jun 29 '12 at 15:50
