      2 Android ScreenCapture Sample
      3 ===================================
      4 
      5 This sample demonstrates how to use Media Projection API to capture device screen in real time and
      6 show it on a SurfaceView.
      7 
      8 Introduction
      9 ------------
     10 
     11 Media Projection API lets you capture the current screen through Surface.
     12 
     13 To start media projection, you need to get an instance of [MediaProjection][1]. For this, you have
     14 to call startActivityForResult with an Intent from
     15 [MediaProjectionManager.createScreenCaptureIntent()][2]. This shows a confirmation dialog to the
     16 user. When user confirms it, you will get a result code and data in onActivityResult, so pass those
     17 to [getMediaProjection][3].
     18 
     19 Once you get a MediaProjection, use [createVirtualDisplay][4] and bind it to a Surface.
