I have done exactly what the thread shows. It reports this crash when app is running for the first time only. The app does not crash. It just shows this error message.

I have v10.2 and lastest SDK.

I found the solution. The Crashlytics thread should say OKHttpUtils2 library is required. I have included that library and the error is gone. I think it might be related to Crashlytics. I recently added that.
