[Android] App crash on opening without internet

[MaxMichel2]

I noticed this by accident but opening the app without internet causes a crash on Android.

I'm interested in debugging and fixing this myself so I'll try to fix it in the near future.

Thanks for the bug report and sorry for the delayed response, these last 2 days have been quite something! Please feel free to open a pull request if you find the root cause of the issue. FWIW, we have a few crashes like below in the Google play console. Might be a good place to start:

Exception y9.o: A network error (such as timeout, interrupted connection or unreachable host) has occurred.

@MaxMichel2 turns out we had the issue in another repo as well. I made a tentative fix workaround in #303
