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. For this, you have to call startActivityForResult with an Intent from MediaProjectionManager.createScreenCaptureIntent(). 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.
