Android Studio import module cannot resolve symbol

Question

I'm using latest Android Studio version (2.3.1) and I imported a library to my android studio project.
But when I want to import classes :

import com.mehdikarimi.PauseResumeAudioRecorder;      

returned error :

Is any suggestion to resolve this error?

Answer 1

Check settings.gradle file, Is your module included there.

like include 'abc', 'xyz'

If yes try to Invalidate Caches/Restart and restart Android Studio.

Answer 2

I resolved the problem first Invalidate Caches/Restart and closed Android Studio and deleted *.iml files and .idea folder then I added

    compile project(path: ':audiorecordlibrary');

To app dependencies
