Android DirectShare Sample
===================================

Sample demonstrating how to show some options directly in the list of share intent candidates.

Introduction
------------

[Direct Share][1] is a feature that allows apps to show their internal options directly in the
system Intent chooser dialog. This sample is a dummy messaging app, and just like any other
messaging apps, it receives intents for sharing a plain text. When a user shares some text from some
other app, this sample app will be listed as an option. Using the Direct Share feature, this app
also shows some of contacts directly in the chooser dialog.

To enable Direct Share, apps need to implement a Service extending
[ChooserTargetService][2]. Override the method [onGetChooserTargets][3] and return a list of Direct
Share options.

In your AndroidManifest.xml, add a meta-data tag in your Activity that receives the Intent. Specify
android:name as android.service.chooser.chooser_target_service, and point the android:value to the
Service.
