ResolverActivitypublic class ResolverActivity extends AlertActivity implements CheckBox.OnCheckedChangeListener, DialogInterface.OnClickListener| This activity is displayed when the system attempts to start an Intent for
which there is more than one matching activity, allowing the user to decide
which to go to. It is not normally used directly by application developers. |
