I'm considering the use of keepSynced() for some data from Firebase Realtime Database. I understand that it will automatically sync those paths. But how does that relate to Android lifecycle? If the user leaves all activities (and all normal listeners disconnect), will it stop syncing? I don't want the app to become data or battery hog.
On the other hand, I would like to update cached data when FCM notification arrives. I can launch some service which will connect to Firebase. I would like to sync all paths which are in keepSynced() and stop it when it's synced. I'm not sure how to achieve that. Create a listener to one of the paths and keep the service running for some time? After the service is finished, will it stop syncing?
