App stops working on Android 7 (NoSuchMethodError)
Describe your problem!
An Android 7 user contacted us, that after activating the statubar icon option the app crashes. Afterwards the app can no longer be started.
It seems this function is not supported.
How to reproduce?
- Use Android 7 (emulator)
- Start WhereYouGo
- Activate settings - Appearance - StatusBar Icon
- Close WhereYouGo
- Open WhereYouGo again
Actual result after these steps?
App can no longer be started but crashes on startup

Hi there just checked and there are some issues with the code in menion.android.whereyougo.utils.NotificationService. That class is using API 26+ features. I am not experienced enough in Android programming but it looks to me that at least this part of the code requires Android 8 and higher and some backport would be necessary, i guess. Kind of confusing as the gradle file indicates the project to be compatible to API 21.
Using NotificationCompat seems to fix this error, tested against API 23 (Android 6), see PR #418
