title: duplicate entry: com/google/android/gms/common/SupportErrorDialogFragment.class
body: <p>I am creating project in android studio with multi dex support . I am getting error : java.util.zip.ZipException: duplicate entry: com/google/android/gms/common/SupportErrorDialogFragment.class . I know this issue is for duplicate class. But unable to figure out that which class is getting duplicate and how to fix it. Below are the code of my build.gradle. Please suggest. Thanks.</p>
