Android Pie - 9 (API 28) : Installing APK … not successfully installing

问题

Recently I have updated OS to Android 9(Pie) and found that Whenever I try to install APK from android studio it does not work.

As it just shows "Installing Apk..." and freezes at that point, After waiting too long it shows "Application Installation Failed" with "Installation failed with message null."

Did anyone else is facing this issue? If yes then help, please.

Here is the attached screenshot.

Device and Enviornment Details :

Device : MI A1

Android Studio : 3.2.1

Any Help, Idea, Suggestion will be highly appreciated.

Please follow the below steps to fix the problem..

1. Go to settings and turn off your Developer Options.
2. Restart your device.
3. Go to settings again and turn on your Developer Options back (By hitting the Build Number multiple times).

Now you are able to install APKs from your Android Studio as you were earlier. Restarting the device is optional but better do that.
