I have just installed Android Studio and I am a beginner in app programming. I got the following error when I first launched the Android Studio.
Rendering problems
The following classes could not be found
- android support.v7.internal.widget.ActionBarOverlayLayout (Fix_Build_Path, Edit_XML, Create_Class)
Tip: Try to build the project
What might be the cause of this error and how should I fix it?
