java - How to make a screen wake up when a notification is received?

Question

For my app I'm trying to get it where the notification wakes up the screen and displays a view from the app. I can't figure how to get the app to wake up when its in a lock screen. I've tried a few things but none seem to work or they crash the app.

There 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
}
