problem with KeyGuardManager

I am trying to use the KeyGuardManager to unlock the phone easily. so far no problems the phone is unlocked and all is good. However when this code is executed later I notice my phone is behaving weirdly. until a I see the following message in the Logcat file :

WindowManagerService.mKeyguardTokenWatcher: cleaning up leaked reference

meaning as far as I can tell the reference to the key-guard was leaked. I have no idea why this would happen especially as I cannot see a method which seems开发者_Go百科 to safely dispose of the keyguard lock.

The code that aquaired the lock looks like this:

// use KeyGuardManager to automaticly unlock the device
    KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    KeyguardLock kgl = kgm.newKeyguardLock("BusSnooze");

    if (kgm.inKeyguardRestrictedInputMode())
        kgl.disableKeyguard();

Anyone know why this is happening? thanks, Jason

I soulved this by using:

kgm.exitKeyguardSafely()
