35/**
36 * This example illustrates the use of the ShareCompat feature of the support library.
37 * ShareCompat offers several pieces of functionality to assist in sharing content between
38 * apps and is especially suited for sharing content to social apps that the user has installed.
39 *
40 * <p>Two other classes are relevant to this code sample: {@link SharingReceiverSupport} is
41 * an activity that has been configured to receive ACTION_SEND and ACTION_SEND_MULTIPLE
42 * sharing intents with a type of text/plain. It provides an example of writing a sharing
43 * target using ShareCompat features. {@link SharingSupportProvider} is a simple
44 * {@link android.content.ContentProvider} that provides access to two text files
45 * created by this app to share as content streams.</p>
