AlarmManager and WakeLock

Question

I want to use an alarm manager in my activity. I set up an alarm at the onPause method of main activity like this,

Intent intent= new Intent(namaz_vakti_acti         


        

Answer 1

I was facing the same problem and the most interesting thing was that it was working on Samsung Galaxy S duos but not Galaxy Nexus. My solution was to create a static lock in Broadcast reciever onReciever() method.

private static PowerManager.WakeLock wakeLock;

public static void acquireWakeLock(Context ctx) {
    if (wakeLock != null)
        wakeLock.release();

    PowerManager pm = (PowerManager) ctx
            .getSystemService(Context.POWER_SERVICE);
    wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK
            | PowerManager.ACQUIRE_CAUSES_WAKEUP
            | PowerManager.ON_AFTER_RELEASE,
            "aqs_wake_lock");
    wakeLock.acquire();
}

public static void releaseWakeLock() {
    if (wakeLock != null)
        wakeLock.release();
    wakeLock = null;
}

call acquireWakeLock() before calling startActivity() and then in OnCreate() method of launched activity I was playing the alarm sound after some delay i.e. in onPause() and on stopping alarm sound, I am finishing the activity and releasing the wakeLock by calling releaseWakeLock().

new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            playSound(getApplicationContext(), getAlarmUri());
        }
    }, 1000);

Hope it will help for someone.
