This is my File structure

I tried to migrate this project to android studio. The Gradle file is also not generating due to this Error. So please Suggest a good way to overcome this ... Thanks in Advance

Answer 1

Change your appcompat build target to Android 5.0

Then your project too.. then rebuild it
