Gradle Exclude Module Does Not Work?

When checking for library dupplication, I ran androidDependencies and got this: +--- com.melnykov:floatingactionbutton:1.2.0 | \--- com.android.support:recyclerview-v7:21.0.2 +-

Solution 1:

For everyone who has the same problem as me (dexDebug throws Exception saying a library is already added - related to support_v4) maybe this will help you: Go to bin/dexedLibs and find the redundant libraries (in my case it is the nineoldandroids since android_support_v4 already has it) and rebuild your project. However you should do this at your own risk so remember to back up the files before attempting to delete them.
