When we receive notifications indicating that the app has changed, the
App object needs to be changed and the view updated.
These notifications can be received from two sources:
- the ContentObserver;
- onActivityResult().
Thus, the implementation should not be related to the ContentObserver
(in theory, we might want to keep only the onActivityResult()
notification). Therefore, move it to a separate method in AppDetails.
This also preventively avoids bugs when the ContentObserver is null.
