I made an Android project on Android Studio. When I ran it on test Android device which was plugged to my system using a USB cable, it ran successfully.
However, then I generated the APK and uploaded in Diawi website. When I tried to install this APK, I got following error:
App not installed.
The package appears to be corrupt.
APK file however is not corrupt at all since when I installed it manually after copying it from build
folder, it was successfully installed on the Galaxy S7.
How to fix this issue?
