Android studio keeps telling me project is in old format even though I already have it converted (2 times actually - now it says the backup will be stored in projectFilesBackup3). Clicking details reveals this:
RunConfigurations of type JUnitConfiguration will be converted to AndroidJUnitConfiguration. JUnit tests and Android Instrumented tests will work properly together.
It works but is just inconvenient. What is interesting is that all those backup directories are empty. Still, how do I resolve this permanently?
