Answer 1

goto .idea folder open modules.xml file and see for yourself what module is there that you are not using in project currently.

Answer 2

Copy the project files from the original source and paste it somewhere and then import from the Android Studio.

Answer 3

Change the directory of the Project and re-open.

Answer 4

1. Close the project
2. Just delete the modules.xml in .idea folder.
3. Open the project again.

Answer 5

In my case settings.gradle contained invalid configuration.

I changed:

include ':app'
rootProject.name='<somthing else>'

To:

include ':app'

Error is gone. So maybe check your settings.gradle for potential errors. If this won't work try to remove cache and other tips.

Answer 6

Make sure you have added your module to the settings.gradle file:

include ':app'
include ':your-module'
