Android ScreenCapture Sample
===================================

This sample demonstrates how to use Media Projection API to capture device screen in real time and
show it on a SurfaceView.

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

Media Projection API lets you capture the current screen through Surface.

To start media projection, you need to get an instance of [MediaProjection][1]. For this, you have
to call startActivityForResult with an Intent from
[MediaProjectionManager.createScreenCaptureIntent()][2]. This shows a confirmation dialog to the
user. When user confirms it, you will get a result code and data in onActivityResult, so pass those
to [getMediaProjection][3].

Once you get a MediaProjection, use [createVirtualDisplay][4] and bind it to a Surface.
