App not loading when no internet connection available

[osmose991]

Thanks for this apps, we really like it here. Better than most music apps with subsonic api.

Problem : When there's no wifi available and no data connection (cellular) The app is not loading and crash at start. (It's still works if loaded before losing internet access)

Step to reproduce :

1. Flush apps in memory
2. Turn off wifi
3. Turn off LTE
4. Open the app (Should close automatically)

Hello, could you reproduce the crash with an unsigned apk to have a more readable crashlog? I can't reproduce the problem and I've made a slight change that may affect the behavior of that part of the system.

Hi, I've been trying your app from the previous post, and it's working normally. I can't reproduce the crash with this app (app-notquitemy-debug.zip). So your slight changes seem to be working great.

Great!
