I am having difficulty importing a project written on Android Studio 1.1 into Android Studio 2.1.2. I keep getting this error whenever the gradle is building before testing the app on a tablet. Below is a screen shot of the error. Does anyone know what the problem could be?

I have tried adb kill-server followed by adb start-server as well as some other gradle versions compatible with the project. Other than this, I have not been able to find many more suggested solutions to the problem ("session 'app': error installing APK").

Additionally, I have tried uploading a basic Hello World project which successfully built the gradle.
