__**Clear Application data Screen**__

This screen allows the system user to prevent/allow the mobile user to clear an app's Data. The whitelist is the exception to the blacklist, so if a package name appears in both lists, the whitelist takes priority.



Below is the Clear Data screen.

**__Get All Apps__**

This will refresh the All Apps list which contains all the apps currently on the device.


**__Get Clear Data Blacklist__**

This refreshes the Blacklisted Packages list. It contains all the apps that have been blacklisted by the system user for that device.

**__Add Apps To C/D Blacklist__**

This sends the blacklisted apps to the device. The apps are the apps selected from the all apps list.


**__Remove Apps From C/D Blacklist__**

This sends the blacklisted apps to the device that are to be removed from the blacklist. These apps are the apps selected from the all apps list.

**__Add/remove Package Name__**

If the system user knows a package name of an app, the package name can be entered in this box. It will be added to the blacklist. 
The * (asterisk character) can be used to specify all package names. The * is a wild card character and can be used replace other characters.
For example, com.abc.def.ghi could be blacklisted by entering:

  * com.abc.def.ghi
  * com.abc.def.*
  * com.abc.*

com.abc.* would also block the following package name com.abc.xyz



**__Whitelisting__**

The same functionality applies to whitelisting any apps, but please remember a whitelisted app is the exception to a blacklisted app. So if the same app appears in both lists, the app will be whitelisted and the mobile user will still be able to clear the data.
