Subject: [PATCH] Modify conditions for preventing updated system apps from
|
||
|
|
being downgraded
|
||
|
|
|
||
|
|
Add two conditions prior to deciding whether a specific user can downgrade system apps by deletePackageX.
|
||
|
|
1.uninstalledPs must be a updated system app.
|
||
|
|
2.deleteFlags does not contains PackageManager.DELETE_SYSTEM_APP, since flag PackageManager.DELETE_SYSTEM_APP
|
||
|
|
will just mark the app as uninstalled for the specific user instead of uninstalling the update and rolling back
|
||
|
|
to the older system version.
|
||
|
|
|
||
|
|
Test: Update a system app and create some multi users; Then use command "pm uninstall --user ${userId} ${packageName}"
|
||
|
|
to uninstall the system app for a specific user; The result is that the system app is marked as uninstalled for
|
||
|
|
this specific user successfully
