InstalledAppDetailspublic class InstalledAppDetails extends android.app.Activity implements DialogInterface.OnClickListener, View.OnClickListener| Activity to display application information from Settings. This activity presents
extended information associated with a package like code, data, total size, permissions
used by the application and also the set of default launchable activities.
For system applications, an option to clear user data is displayed only if data size is > 0.
System applications that do not want clear user data do not have this option.
For non-system applications, there is no option to clear data. Instead there is an option to
uninstall the application. |
