Light up screen when notification received android

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);
}

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
}
