title: Disable clear data and uninstall update /system/app/
body: <p>I have an application that comes baked onto about 10 un-rooted device OS's. Located in /system/app. 
  We're trying to update the application and prevent the users from uninstalling a critical update or clear the data. How could we go about disabling the "Clear Data" And "Uninstall Update" in the manage applications menu.</p>
