Benefits of the refactor:
- can support screen rotation when choosing an account
- reduce complexity in SendActivity
Also change the minSdkVersion to 7 so that
- in AccountChooserActivity, can just use the Android AccountManager
- in SendActivity, can use Account
- in SendActivity, can remove the Constants.GET_LOGIN callback
from the legacy AuthManager (AuthManagerOld)
to pick the Google services to send a track to.
Benefits of the refactor:
- ServicePickerActivity can easily handle screen rotation
- Reduce complexity in SendActivity
