Wakelock not working at all

Question

What's missing in here? I want to wake up the device from sleep, but nothing happens. I certainly do not want to prevent sleeping.

final Handler handler = new Handler(); 
Runnable runable = new Runnable() { 
            @Override 
            public void run() { 
            try{
                wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK |  PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
                         wl.acquire();
                         wl.release();

                Log.v("INTERVAL: ", "NOW" );
                handler.postDelayed(this, 5000);
            }
            catch (Exception e) {
                        // TODO: handle exception
            }
     }

this is the log: as it was asked; hope it helps to find out whatever you need

Can you attach the logs? – mittelmania Aug 11 '14 at 16:54 — mittelmania, Aug 11 '14 at 16:54

The wl.release(); should be called only when the job is finished. If you acquire() and release() right away, nothing will happen. Try this:

 final Handler handler = new Handler(); 
 Runnable runnable = new Runnable() { 
        @Override 
        public void run() { 
            try{


                 wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
                 wl.acquire();

                //PUT HERE THE CODE YOU WANNA EXECUTE

                 wl.release();

            }
            catch (Exception e) {
                // TODO: handle exception
            } }
      };


       Log.v("INTERVAL: ", "NOW" );
       handler.postDelayed(runnable, 5000);

Also, make sure you put the permission on your manifest file:

 <uses-permission android:name="android.permission.WAKE_LOCK" />

A) tnx for the answer, B) I have the permission C) mmm, I tried your code, its not working. All I wanna do is just wake up the screen for now. – Shervin Aug 11 '14 at 16:56
actually this code 'prevents' the device from sleeping..it doesn't really wake up the screen. Where are you running it from? You should certainly need to run it from a BroadcastReceiver (scheduled to be executed (waking up the device)). You actually don't need a Handler when executing on the BroadcastReceiver...also You should probably check the types of locks: http://developer.android.com/reference/android/os/PowerManager.html – Alécio Carvalho Aug 11 '14 at 17:00
to tell you my exact goal; I want to wake up screen when my gps coords are reached to specific value, so I need to call a broadcast. right? – Shervin Aug 11 '14 at 17:09
Maybe you could consider using the http://developer.android.com/guide/topics/ui/notifiers/notifications.html waking up the screen out of the sudden might not be useful..imagine if the phone is in the pocket, nobody will see it. But with Notifications you can attach some sound and vibration and let the user decide whether or not open your app. See it here: http://developer.android.com/guide/topics/ui/notifiers/notifications.html – Alécio Carvalho Aug 11 '14 at 17:35
