Hi Danny,

Greetings from ShepHertz!!!!

Here are the possible reasons why you are getting  java.io.IOException: Failed to generate v1 signature.

1. Either some of assets or resource file is not valid.
2. There may be error build.gadle file.

Or may be others as well. This is not related the SDK you have integrated in your project.
