Hi yusong,

If you want to proguard your project, you need add zoom sdk proguard rules, please get the rules from the below link:

[https://github.com/zoom/zoom-sdk-android/blob/master/proguard.cfg](https://github.com/zoom/zoom-sdk-android/blob/master/proguard.cfg)

Thanks.

After adding all the rules for progaurd I am getting a lot of warnings. Adding some of them for reference :

Warning:Interface `us.zoom.thirdparty.login.facebook.FBAppAuthCallBack` not found. It’s needed to make sure desugaring of `com.zipow.videobox.LoginActivity$1` is correct. Desugaring will assume that this interface has no default method.

Hi goyal.arun16,  
Thanks for using Zoom SDK. You can use ‘keep’ in proguard rules to avoid having these warnings, such as `-keep com.zipow.videobox.LoginActivity`.

Let me know if you have any questions. Thanks!
