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