Answer 1

PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = pm.isScreenOn();
Log.e("screen on........", ""+isScreenOn);
if(isScreenOn==false)
{
    WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE,"myApp:MyLock");
    wl.acquire(10000);
    WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"myApp:mycpuMyCpuLock");

    wl_cpu.acquire(10000);
}

Indentation

FULL_WAKE_LOCK is deprecated now. What use instead? – Noncompliance

I have the same question as Orium. – Kinky

you need WakeLock permission in manifest: <uses-permission android:name="android.permission.WAKE_LOCK" /> – Neuropathy

isScreenOn() was deprecated in API level 20. Use isInteractive() instead. – Foresaid

Thanks. You solved my issue for wake up lock. Now my app properly wake up for notifications. – Pogy

FULL_WAKE_LOCK is deprecated. Use PARTIAL_WAKE_LOCK instead. – Hostility

@KaiWang Are we supposed to use PARTIAL_WAKE_LOCK on both wl and wl_cpu instances? – Belligerency

@Belligerency I'm not sure about it. Sorry dude :) – Hostility

PARTIAL_WAKE_LOCK will not wake up a device on its own, and the Android docs state it cannot be used with ACQUIRE_CAUSES_WAKEUP – Watkins

will this code come after notification code in broadcastreceiver? – Televisor

Answer 2

Here is my solution:

createNotification(); //your implementation
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = Build.VERSION.SDK_INT >= 20 ? pm.isInteractive() : pm.isScreenOn(); // check if screen is on
if (!isScreenOn) {
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "myApp:notificationLock");
    wl.acquire(3000); //set your time in milliseconds
}
