Answer 1

If you are using IntelliJ with Gradle, you may need to unlink a non-existent module in the Gradle tab.

Answer 2

The issue might also be caused by an empty 'Gradle project:' field under:

'Run'
  -> 'Edit Configurations...'
  -> 'Gradle'
  -> 'NAME OF YOUR CONFIGURATION'
  -> 'Configuration'
  -> 'Gradle project:'

Filling out this field by selecting the root directory of my application (an clicking on 'Apply') resolved the issue for me.

Answer 3

Delete .idea and .gradle folders and try to re-import the project. I had refactored my project name and I ran into the issue and deleting .idea and .gradle folders and re importing worked as it clears the meta data of project configuration for intellij or android studio.

Answer 4

Navigate to "File" and select "Invalidate Caches and Restart" from the drop down. After Android Studio restarts, your project should run.
