Session 'app' error while installing APK

Question

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

Answer 1

In my case, my project location contained the special character.

E:\Android_Projects\T&PUIET,KUK\app\build\outputs\apk\app-debug.apk

close android studio > rename folder containing the special character(here T&PUIET,KUK ) > restart android studio.

Hope this Solution helps!
