IntentService with AlarmManager

Question

I want to re-start my IntentService (which handles HTTP POST request) every 10 seconds. I tried using AlarmManager and PendingIntent as descrribed in every posts. But my IntentService doesn't starts. I'm unable to find any reason for this so any help would be appreciated.

IntentService

public class MyService extends IntentService{

    public MyService() {
        super("MyService");
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // TODO Auto-generated method stub
        Toast.makeText(getApplicationContext(), "Service Started", Toast.LENGTH_SHORT).show();
      System.out.println("Service Started");
        // POST request code here
    }
}

MainActivity

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        start();
    }

    public void start() {
         Intent intent = new Intent(this, MyService.class);
            intent.putExtra("com.hybris.proxi.triggerTime", 5000);
            PendingIntent pendingIntent = PendingIntent.getService(this,  0,  intent, 0);
            long trigger = System.currentTimeMillis() + (5*1000);
            AlarmManager am =( AlarmManager)getSystemService(Context.ALARM_SERVICE);
            am.set(AlarmManager.RTC_WAKEUP, trigger, pendingIntent);
    }
}

You can use this code:

 final Handler handler = new Handler();

        TimerTask timertask = new TimerTask() {
            @Override
            public void run() {
                handler.post(new Runnable() {
                    public void run() {
                        startService(new Intent(getApplicationContext(),
                                MyService.class));
                    }
                });
            }
        };
        Timer timer = new Timer();
        timer.schedule(timertask, 0, 10000);
        }

This will execute at an interval of 10 seconds

Also,add your Service class to manifest:

       <service
            android:name=".MyService"
            android:enabled="true" >
        </service>

Where I add this Runnable? In my start() method? – Somnath Pal Oct 09 '15 at 06:01
When do u call the start() method?? – Jas Oct 09 '15 at 06:04
I called it in onCreate – Somnath Pal Oct 09 '15 at 06:08
Then you can either write this code inside `onCreate()` or inside your `start()` method. – Jas Oct 09 '15 at 06:09
I tried both in start() method and in onCreate but it still not working. If the IntentService starts it will display a Toast. But no Toast showing. – Somnath Pal Oct 09 '15 at 06:13
Yes I added Service in Manifest just like you told. – Somnath Pal Oct 09 '15 at 06:18
Try debugging and check whether Service class start method is getting invoked – Jas Oct 09 '15 at 06:22
Yes. LogCat displays the System.out message. But it doesn't repeat in every 10 sec which means the Service is not getting started again. – Somnath Pal Oct 09 '15 at 06:30
Where did you write this code?onCreate or your method? – Jas Oct 09 '15 at 06:45
I created a start() method in onCreate `private void start() { // TODO Auto-generated method stub Runnable runnable = new Runnable() { public void run() { startService(new Intent(MainActivity.this, MyService.class)); } }; Handler handler = new Handler(); handler.postDelayed(runnable, 10000); } ` – Somnath Pal Oct 09 '15 at 06:48
Try writing it directly inside onCreate – Jas Oct 09 '15 at 06:50
Nope. Same result. LogCat output: SVC-Destroying service: com.example.alarmmanager.MyService@41d56728 threadid=13: exiting threadid=13: bye – Somnath Pal Oct 09 '15 at 06:59
Any other way to restart my intentservice even if the app is not opened? – Somnath Pal Oct 09 '15 at 07:01
See the updated code.This will surely work.Add it inside your onCreate() not in start() – Jas Oct 09 '15 at 07:20
You are amazing Jas. Its working. The service is getting started again now. – Somnath Pal Oct 09 '15 at 07:33
I think its working even after I've closed the app. Really u r genius man! – Somnath Pal Oct 09 '15 at 07:36
It's a Service class.Always works in background :D Do upvote also – Jas Oct 09 '15 at 08:12
