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.
