I have search many times to solve this error. My apps going well when build with no signed but it getting error when build Signed Bundle/APK. I used zoom meeting android SDK in my project with module name mobilertc and commonlib. i have included multidex depedencies and try to delete .gradle file then invalidate/restart android, but it still get error like this :

Type a.a.a.a.a is defined multiple times: C:\Users\AndroidStudioProjects\android-zoomsdk\mobilertc\build.transforms\135bfa37c7ff11bc18f4ecf26c77ccbe\jetified-mobilertc-runtime\classes.dex, C:\Users\AndroidStudioProjects\android -zoomsdk\app\build\intermediates\external_libs_dex\developmentRelease\mergeExtDexDevelopmentRelease\classes.dex

I need to generate my Signed Bundle/APK that used to upload to play store. I really appreciate your answer. Thanks.
