Did you follow the steps in https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-android#2-create-a-user-pool and replacing the values in https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-android#4-build-and-run-the-demo-application-using-android-studio with proper value? If not setting properly, currently the exception will cause app to crash. Thanks.
