Solution 1

First of all you should update to Android Studio 1.2 Source: https://code.google.com/p/android/issues/detail?id=77983

Then you should go to File -> Invalidate Caches / Restart -> Invalidate Caches & Restart.

Then try to build the application again.

Solution 2

1- close the project

2- close Android Studio IDE

3- delete the .idea directory located inside the project folder

4- delete all .iml files

5- open Android Studio IDE and import the project

Solution 3

Invalidate Caches and Restart did not work for me. I also updated all my Android Studio files with no success.

The solution I found was importing the android folder by clicking "Import project (Eclipse ADT, Gradle, etc.)" rather than clicking "Open an existing Android Studio Project" or dragging the folder onto the app icon.

Apparently the problem is caused because a module in the project has an *.iml file that does not contain external.system.id="GRADLE".

When you import the project (as opposed to opening it), the iml files are completely re-written, thus removing the error.

I found the info here: https://issuetracker.google.com/issues/37008041

Solution 4

Goto .idea/modules.xml & delete the invalid/not existing path <module />. Then File => Invalidate Caches / Restart.

Solution 5

Try this if it helps File -> Invalidate Caches / Restart.

If it still doesn't help click on the button in the image. 'Sync Project with Gradle Files'
