Hi All,

I have already implemented the retrofit for the Rest API’s in my app and now I’m trying to implement the ZOOM sdk but after importing the zoom sdk I tried to run the app and its giving me the following error:

“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”

I tried to exclude the gson from the sdk but it didn’t work.

Hi,&nbsp;

could I get more details on how you import the project? Did you also include other libraries?

Best
