Crashes on Android

Client Libraries

I did simple setup with c++ sdk for Android project, connect → upload/download user profile, nothing more. And get a lot of crashes, something like this, any ideas how to avoid/fix it?

To help with this we need more info;

  1. Can you please add code examples and point us to where your game crashes?
  2. Can you tell us which SDK and what version you are using?
  3. What Android SDK/NDK and what phone/version is this running on?
  4. Does it happen all the time?

Thanks
