I have been battling this error all day in Android Studio. Project was imported from an eclipse solution. I have been trying to implement all fixes that are listed for similar posts, nothing is working. I am an Android beginner.
I will be happy to provide any further information.
Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
java.util.zip.ZipException: duplicate entry: com/google/zxing/BarcodeFormat.class
Please help!! Should I just try to get it to run in Eclipse?

Make sure you have the latest build toolds and sdk from the SDK manager. I have converted those jars
to Gradle
dependencies.
