| ↳ | android.content.pm.PackageManager |
| |
| abstract void | addPackageToPreferred(String packageName)
This method is deprecated. This function no longer does anything; it was an old approach to managing preferred activities, which has been superceeded (and conflicts with) the modern activity-based preferences.
|
| abstract boolean | addPermission(PermissionInfo info)
Add a new dynamic permission to the system.
|
| abstract boolean | addPermissionAsync(PermissionInfo info)
Like
addPermission(PermissionInfo) but asynchronously persists the package manager state after returning from the call, allowing it to return quicker and batch a series of adds at the expense of no guarantee the added permission will be retained if the device is rebooted before it is written.
|
| abstract void | addPreferredActivity(IntentFilter filter, int match, ComponentName[] set, ComponentName activity)
This method is deprecated. This is a protected API that should not have been available to third party applications. It is the platform's responsibility for assigning preferred activities and this can not be directly modified. Add a new preferred activity mapping to the system. This will be used to automatically select the given activity component when Context.startActivity() finds multiple matching activities and also matches the given filter.
