Question

Currently I am working on a mobile based application using Flex 4 and action script 3. Normally for locking android phones, we need to press the lock button, but I want to lock the android phone by application.

Is there any API available for this? I need to lock the phone by running the application, which is created using Flex 4 and action script 3. Please give me some idea for this..

Answer 1

Using Flex 4 is little difficult. better you can try with native android application. There are some options are available, like

KeyguardManager mgr = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE); 
KeyguardLock lock = mgr.newKeyguardLock(KEYGUARD_SERVICE); 
lock.reenableKeyguard();

and another way is android.os.PowerManager

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
wl.acquire();
//and use 
wl.release();

The detail description about PowerManager you can find from here.
