Hi,
I'm trying to programatically turn the screen off and on, while keep
the app running.
If i try this code:
final PowerManager pm = (PowerManager)
loader.getSystemService(Context.POWER_SERVICE);
AndroidUtils.debug("creating lock");
screenLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK,
"TotalCross");
AndroidUtils.debug("lock: "+screenLock);
screenLock.acquire();
AndroidUtils.debug("acquired: "+screenLock);
... then the application stops at the "acquire" method call
("acquired" is never printed).
If i change to:
PowerManager pm = (PowerManager)
loader.getApplication().getSystemService(Context.POWER_SERVICE);
(note the getApplication()), then i get:
java.lang.SecurityException: Neither user 10030 nor current process
has android.permission.WAKE_LOCK.
Am I missing something here?
thanks
guich
