Auto install preference always runs after a sync, even if it's manual.
The names of the preference & strings have been updated to reflect this
new behaviour.
Sets preference for auto updates to true by default if device runs
Android 12 and later.
Reverts change allowing the install prompt to show up from the
background and instead require the notification on all Android versions.
Initial implementation of fully automatic updates, allowing apps to be
updated after a repo sync has been completed. It can be enabled with a
new preference in settings.
Implemented by greatly modifying SyncService to allow updates to be run
on every completed sync before notifications would be outputted. Note
that the update notification no longer appears if auto updates are
enabled.
BuildConfig.DEBUG is used to force syncing to run to completion, even if
there are no changes to the repos. This allow reliable testing by
turning the sync button into an "update all" button. This should be
removed once an "Update all" button has been implemented in the updates
tab.
Cache file checking in DefaultInstaller is now more robust.
