Hello,  
I followed your tutorial at:  
[https://www.wowza.com/docs/how-to-build-a-basic-app-with-gocoder-sdk-for-android](https://www.wowza.com/docs/how-to-build-a-basic-app-with-gocoder-sdk-for-android)

My code is the same of the tutorial.

The app compiles, but I get the following crash at app startup on my Android 7 device:
