Finding solutions in the following links:
java.lang.NoClassDefFoundError: javax.activation.DataHandler
java.lang.NoClassDefFoundError: javax.activation.DataHandler in android
I understand that this exception is due to android not implementing java.awt.datatransfer classes. I tried the solutions but they didnt work. When i added javax.mail 1.5.5 in gradle it shows a duplicate file copied error.
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/mimetypes.default
File1: C:\Users\Taha\.gradle\caches\modules-2\files-2.1\com.sun.mail\android-activation\1.5.6\34c941857c08ff1d6af9a43a8806342883b2a8e1\android-activation-1.5.6.jar

I couldnt find any solutions for this. I tried excluding excluding file in gradle packaging options, it didnt work only throwing NoClassDefFound exception again.
Any help would be appreciated.
