The extra data EXTRA_CHANGED_PACKAGE_LIST contains a list of packages whose availability changed. The extra data EXTRA_CHANGED_UID_LIST contains a list of uids of packages whose availability changed. Note that the packages in this list do not receive this broadcast. The specified set of packages are now available on the system.

FLAG_ACTIVITY_TASK_ON_HOME

public static final int FLAG_ACTIVITY_TASK_ON_HOME

If set in an Intent passed to Context.startActivity(), this flag will cause a newly launching task to be placed on top of the current home activity task (if there is one). That is, pressing back from the task will always return the user to home even if that was not the last activity they saw. This can only be used in conjunction with Intent.FLAG_ACTIVITY_NEW_TASK.

See Also:: Constant Field Values

FLAG_ACTIVITY_CLEAR_TASK

public static final int FLAG_ACTIVITY_CLEAR_TASK

If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be associated with the activity to be cleared before the activity is started. That is, the activity becomes the new root of an otherwise empty task, and any old activities are finished. This can only be used in conjunction with Intent.FLAG_ACTIVITY_NEW_TASK.

This flag will only be obeyed on devices supporting API 11 or higher.

Method Detail

makeMainActivity

public static android.content.Intent makeMainActivity(android.content.ComponentName mainActivity)

Create an intent to launch the main (root) activity of a task. This is the Intent that is started when the application's is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.

The returned Intent has the given Activity component as its explicit component, ACTION_MAIN as its action, and includes the category CATEGORY_LAUNCHER. This does not have FLAG_ACTIVITY_NEW_TASK set, though typically you will want to do that through addFlags(int) on the returned Intent.

Parameters:: mainActivity - The main activity component that this Intent will launch.
Returns:: Returns a newly created Intent that can be used to launch the activity as a main application entry.
See Also:: Intent.setClass(android.content.Context, java.lang.Class), Intent.setComponent(android.content.ComponentName)

makeMainSelectorActivity

public static android.content.Intent makeMainSelectorActivity(String selectorAction,
                                                              String selectorCategory)

Make an Intent for the main activity of an application, without specifying a specific activity to run but giving a selector to find the activity. This results in a final Intent that is structured the same as when the application is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.

The returned Intent has Intent.ACTION_MAIN as its action, and includes the category Intent.CATEGORY_LAUNCHER. This does not have Intent.FLAG_ACTIVITY_NEW_TASK set, though typically you will want to do that through Intent.addFlags(int) on the returned Intent.

Parameters:: selectorAction - The action name of the Intent's selector.; selectorCategory - The name of a category to add to the Intent's selector.
Returns:: Returns a newly created Intent that can be used to launch the activity as a main application entry.
See Also:: #setSelector(Intent)

makeRestartActivityTask

public static android.content.Intent makeRestartActivityTask(android.content.ComponentName mainActivity)

Make an Intent that can be used to re-launch an application's task in its base state. This is like makeMainActivity(ComponentName), but also sets the flags Intent.FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK.

Parameters:: mainActivity - The activity component that is the root of the task; this is the activity that has been published in the application's manifest as the main launcher icon.
Returns:: Returns a newly created Intent that can be used to relaunch the activity's task in its root state.
