screen-lock

In my application I want to detect the shake event and I'm using SensorEventListener, the code is working fine when my activity is running in foreground. But when I press the lock button of the phone to lock the screen, the shake event can't be detected. I have tested my code on the Samsung gts5360. But the same code is working fine on sony ericssion xperia mini pro. Actually my Samsung phone is not detecting the shake events when I leave the device idle for approx. 45 seconds, after locking the device. Then I shake the phone, it does not detect the shake, but when I shake phone after several

Is there a way to lock the Android screen via the ADB? I find ways to lock the display in an apk, but I want to lock the screen from the PC via ADB, to simulate a display timeout, without having to wait for the timeout. Is it possible to do this?

I want to hide all the controls on the locked screen when an app is playing in the background. However, I want the audio related information to be displayed all the time. I read about MPRemoteCommandCenter but we can't implement the below code because when you try to disable all then the screen starts showing 3 controls (toggle button, next track, previous track) MPRemoteCommandCenter *rcc = [MPRemoteCommandCenter sharedCommandCenter]; [[rcc skipForwardCommand] setEnabled:NO]; [[rcc skipBackwardCommand] setEnabled:NO]; [[rcc nextTrackCommand] setEnabled:NO]; [[rcc previousTrackCommand]

Rather than build a passcode directly into my app and potentially require the user to enter a passcode twice (once for the device and again for my app); I thought I might out-clever myself and do something along the lines of: if (device has passcode) continue into my app else make user enter my app passcode I don't want to set the device passcode, I don't want to force a screen lock, not encrypting anything - all I really want is an API just to detect if a device passcode is in effect. Something like: BOOL notReally = [UIDevice isUserSlightlyMoreSecureBecauseTheySetDeviceLockOn]; or maybe if I

How to start an Activity on device even if screen is locked. I tried as below but it's not working. Broadcast receiver: Intent alarmIntent = new Intent("android.intent.action.MAIN"); alarmIntent.setClass(context, Alarm.class); alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); alarmIntent.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED + WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD + WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON + WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); context.startActivity(alarmIntent); You need the following permission in AndroidManifest.xml file:

Is there any one that can help me with a code to set a password to lock the screen ? thx Shaahul Use this code in your App, it works for me: DevicePolicyManager devicePolicyManager = DevicePolicyManager.getSystemService(Context.DEVICE_POLICY_SERVICE); ComponentName demoDeviceAdmin = new ComponentName(this, name of activity); devicePolicyManager.setPasswordQuality( demoDeviceAdmin,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED); devicePolicyManager.setPasswordMinimumLength(demoDeviceAdmin, 5); boolean result = devicePolicyManager.resetPassword("123456", DevicePolicyManager.RESET_PASSWORD
