问题 I am using overlay permission to display certain information in my app. Running it on API 23 - 25 it works fine (asking for permission, granting, etc. according to Unable to add window android.view.ViewRoot$W@44da9bc0 -- permission denied for this window type ). (Many thanks to ceph3us!)

Any idea,

问题 I'm targetting my application to Android O. In my application I have a job service that shows a window over all other applications, so when it triggered it needs to show this window even when the screen is turned off & unlocked and turn it on. I've achieved this behaviour in preior Android versions, but in Android O it doesn't work as I expected. I've read that I need to use the flag TYPE_APPLICATION_OVERLAY and added also the permission <uses-permission android:name="android.permission

问题 My app relies on logging the battery temperature, as well as several other sensor variables, every second in a background service that can be started from the main activity and continues running in the background until it's stopped (by another button in the main activity). This works fine in Android 7.0 and below, but reading into Android 8.0, it looks like it limits background services pretty severely. Can I still do this data logging that I currently do, or is that no longer possible? 回答1:

问题 First off: I know that ConnectivityManager.CONNECTIVITY_ACTION has been deprecated and I know how to use connectivityManager.registerNetworkCallback . Furthermore if read about JobScheduler , but I am not entirely sure whether I got it right. My problem is that I want to execute some code when the phone is connected / disconnected to/from a network. This should happen when the app is in the background as well. Starting with Android O I would have to show a notification if I want to run a
