I searched internet and got 2 codes to unlock android phone programmatically. But none of them I see,use passwords. 1>
KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
final KeyguardManager.KeyguardLock kl = km .newKeyguardLock("MyKeyguardLock");
kl.disableKeyguard();
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK
| PowerManager.ACQUIRE_CAUSES_WAKEUP
| PowerManager.ON_AFTER_RELEASE, "MyWakeLock");
wakeLock.acquire();
2>
WindowManager wm = Context.getSystemService(Context.WINDOW_SERVICE);
//Unlock
Window window = getWindow();
window.addFlags(wm.LayoutParams.FLAG_DISMISS_KEYGUARD);
//Lock device
DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE);
I tried them but could not unlock the password protected screen
