lockscreen

I work on a kiosk app which can launch other android apps. It runs on top of the lockscreen. The issue I am seeing is that the lockscreen is displayed briefly between activities. We must keep the tablet locked so unlocking is not an option. I have been able reproduce this with a super simple case. Both activities are nearly identical. The application is a device administrator and can be displayed above the keyguard. I have also tried not using finish() at all but that didn't fix the issue. public class MainActivity extends Activity { private Handler h = new Handler(); @Override protected void

I'm making a custom lock screen. The lock screen is an activity which I launch by the time the screen goes off. However, I can't make the activity be both transparent & fullscreen. The Status bar keeps showing. Here's what I do in the manifest: <activity android:name=".activities.LockScreenActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/> I'm also adding these extras in activit's onCreate: requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.lock_screen); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager

I have Activity1 which is a list screen of items. Each item can be viewed in a separate Activity2 which is displayed as a popup. Activity1 can be launched from the background and displayed even when the screen is locked. Activity1 may also choose to automatically display the contents of an item in the list screen by starting Activity2 . We can bypass the lock screen because both activities have the WindowManagerFlags.DismissKeyguard enabled in the OnCreate method. Before Android Lollipop everything worked as expected. But now the popup Activity2 is not visible unless the device is manually

I'd like to be able to set the lockscreen background image programmatically. I'm aware that this is only possible for jailbroken iOS devices. Here are some things that I've tried: Place a LockBackground.png in /private/var/mobile/Library/SpringBoard/. This works but requires a hard respring. notify_post("com.apple.language.changed"); doesn't work for a soft respring. Use class-dump to dump private methods of UIKit. UIKit in 4.2 used to have a method called + (void)setDesktopImageData:(id)fp8; but it appears to be missing in 4.3 and above. Is there anything that I'm missing? I found this in the

TL;DR How can I make a notification that does some work from the lock-screen without unlocking? After clicking an action, a button on the notification or just the complete notification, I want to do an API call (without typing my unlock code) Details Goal Based on the answer on this question I tried to make a notification with an action that works on the lockscreen without unlocking the device. The action is something that doesn't need any further interface or interaction (think 'send an API request'). Status The notification and click do work with an unlocked device. However, when locked I

I checked this posting , so it was impossible to do it. But it's old posting, and somebody are saying me there is an app which can change wallpaper(lock screen). Is this allowed now? -- edit -- I'm sorry for my question was unclear. I was asked a programmatic and regular (which can be approved by Apple AppStore) way to change lock-screen wallpaper in my own app. Not for any hacked, jail-breaken devices. As far as I'm aware, you would not be able to change the wallpaper for the device through the SDK, or at least not in a way in which Apple would approve of. I suspect allowing this through the
