Thanks for the reply. Regarding the first video, when switching app, the lock screen will show up few second and disappear before i select the app. Also, at the last of the video, i am going to the home page, but AppLock still need to enter the passwcode. As for the video 2, applock locked the app when sliding down the notification, can applock have option to disable it? Those issues does not exist when i using other applock apps, they can sliding down the notification or switch between apps and lock the app again flawlessly. Maybe the lifecycleListener is not triggered correctly. Please help to investigate it.
