+/**
+ *
+ * This class represents a data model for choosing a component for handing a
+ * given {@link Intent}. The model is responsible for querying the system for
+ * activities that can handle the given intent and order found activities
+ * based on historical data of previous choices. The historical data is stored
+ * in an application private file. If a client does not want to have persistent
+ * choice history the file can be omitted, thus the activities will be ordered
+ * based on historical usage for the current session.
+ *
+ *
+ * For each backing history file there is a singleton instance of this class. Thus,
+ * several clients that specify the same history file will share the same model. Note
+ * that if multiple clients are sharing the same model they should implement semantically
+ * equivalent functionality since setting the model intent will change the found
+ * activities and they may be inconsistent with the functionality of some of the clients.
+ * For example, choosing a share activity can be implemented by a single backing
+ * model and two different views for performing the selection. If however, one of the
+ * views is used for sharing but the other for importing, for example, then each
+ * view should be backed by a separate model.
+ *
+ *
+ * The way clients interact with this class is as follows:
+ *
+ *
+ *
+ *
+ * // Get a model and set it to a couple of clients with semantically similar function.
+ * ActivityChooserModel dataModel =
+ * ActivityChooserModel.get(context, "task_specific_history_file_name.xml");
+ *
+ * ActivityChooserModelClient modelClient1 = getActivityChooserModelClient1();
+ * modelClient1.setActivityChooserModel(dataModel);
+ *
+ * ActivityChooserModelClient modelClient2 = getActivityChooserModelClient2();
+ * modelClient2.setActivityChooserModel(dataModel);
+ *
+ * // Set an intent to choose a an activity for.
+ * dataModel.setIntent(intent);
+ *
+ *

+ *
+ * Note: This class is thread safe.

+ * This is a provider for a share action. It is responsible for creating views
+ * that enable data sharing and also to show a sub menu with sharing activities
+ * if the hosting item is placed on the overflow menu.
+ *
+ * Here is how to use the action provider with custom backing file in a {@link MenuItem}:
+ *
+ *
+ *
+ *
+ * // In Activity#onCreateOptionsMenu
+ * public boolean onCreateOptionsMenu(Menu menu) {
+ * // Get the menu item.
+ * MenuItem menuItem = menu.findItem(R.id.my_menu_item);
+ * // Get the provider and hold onto it to set/change the share intent.
+ * mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();
+ * // Set history different from the default before getting the action
+ * // view since a call to {@link MenuItem#getActionView() MenuItem.getActionView()} calls
+ * // {@link ActionProvider#onCreateActionView()} which uses the backing file name. Omit this
+ * // line if using the default share history file is desired.
+ * mShareActionProvider.setShareHistoryFileName("custom_share_history.xml");
+ * . . .
+ * }
+ *
+ * // Somewhere in the application.
+ * public void doShare(Intent shareIntent) {
+ * // When you want to share set the share intent.
+ * mShareActionProvider.setShareIntent(shareIntent);
+ * }
+ *
+ *
+ *
+ *
+ * Note: While the sample snippet demonstrates how to use this provider
+ * in the context of a menu item, the use of the provider is not limited to menu items.
