I am not sure what this error means.
Execution failed for task \':excelSior:packageAllDebugClassesForMultiDex\'.
> java.util.zip.ZipException: duplicate
For Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug' com.android.build.api.transform.TransformException java.util.zip.ZipException duplicate entry com/google/gson/annotations/Expose.class
Here is what I did:
1) Delete the gson-2.5.jar file. 2) configurations { all*.exclude module: 'gson-2.5' }
