Quickblox And Pro Guard Error

I'm developing an app that uses the Quickblox SDK. If I compile it with minifyEnabled false It work's fine. But if I enable minify to obfuscate the code I get the following error:

Solution 1:

These are the proguard rules that got it working. Hope it helps someone.

Solution 2:

Above answer is not working with me case quickblox video calling , app crashing again and again then i tried another pro guard rules that working.

Go to proguard-rules.pro(app) file in app and copy and paste below all lines. its working
