I am trying to turn on and off the display after a certain action happens (Lets just worry about turning the screen off for now). From what I understand from wake lock, this is what I have:
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
When I read other posts on stackoverflow and else where, they seem to tell me that PARTIAL_WAKE_LOCK will turn the screen off. But if I read the SDK it says that it will only allow the screen to be turned off. So I think this isn't right.
Any hints would be helpful! Thanks,
Mike
There are two choices for turning the screen off:
PowerManager manager = (PowerManager) getSystemService(Context.POWER_SERVICE);
// Choice 1
manager.goToSleep(int amountOfTime);
// Choice 2
PowerManager.WakeLock wl = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Your Tag");
wl.acquire();
wl.release();
You will probably need this permission too:
<uses-permission android:name="android.permission.WAKE_LOCK" />
UPDATE:
Try this method; android turns off the screen once the light level is low enough.
WindowManager.LayoutParams params = getWindow().getAttributes();
params.flags |= LayoutParams.FLAG_KEEP_SCREEN_ON;
params.screenBrightness = 0;
getWindow().setAttributes(params);
