Android IDE (AIDE) Support Forum

Attribute "android:XXXXXX" has already been defined

When I Use

implementation 'androidx.constraintlayout:constraintlayout:2.0.1'

I Always Get This Error

Any Help?
Thank You :slight_smile:

This happens when the IDE contains libraries that have the same values. For example, androidx and support libraries. Try refreshing the libraries from settings. This will delete all libraries and download the libraries that are currently in use.
