In my projects, I need to import third party jar file and Facebook SDK.
compile files(\'libs/SkinSDK.jar\')
compile \'com.facebook.android:facebook-android-
Bumped into similar situation. This is what I did, not elegant as I hoped, but it works:
Rename the jar file (SkinSDK.jar in your case): .zip instead of .jar
Go "inside" the zip file (I'm using DoubleCommander, there are many other utilities for that), or extract it to a temporary folder.
Delete the duplicate class that causes the problem. Go "outside" the zip file.
Rename (or re-pack) the file from .zip to .jar . Compile.
Hope it works...
