1 Android ScreenCapture Sample 2 =================================== 3 4 This sample demonstrates how to use Media Projection API to capture device screen in real time and 5 show it on a SurfaceView. 6 7 Introduction 8 ------------ 9 10 Media Projection API lets you capture the current screen through Surface. 11 12 To start media projection, you need to get an instance of [MediaProjection][1]. For this, you have 13 to call startActivityForResult with an Intent from 14 [MediaProjectionManager.createScreenCaptureIntent()][2]. This shows a confirmation dialog to the 15 user. When user confirms it, you will get a result code and data in onActivityResult, so pass those 16 to [getMediaProjection][3]. 17 18 Once you get a MediaProjection, use [createVirtualDisplay][4] and bind it to a Surface. 19 20 [1]: https://developer.android.com/reference/android/media/projection/MediaProjection.html 21 [2]: https://developer.android.com/reference/android/media/projection/MediaProjectionManager.html#createScreenCaptureIntent() 22 [3]: https://developer.android.com/reference/android/media/projection/MediaProjectionManager.html#getMediaProjection(int, android.content.Intent) 23 [4]: https://developer.android.com/reference/android/media/projection/MediaProjection.html#createVirtualDisplay(java.lang.String, int, int, int, int, android.view.Surface, android.hardware.display.VirtualDisplay.Callback, android.os.Handler) 24 25 Pre-requisites 26 -------------- 27 28 - Android SDK v21 29 - Android Build Tools v21.1.1 30 - Android Support Repository 31 32 Screenshots 33 ------------- 34 35 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 36 37 Getting Started 38 --------------- 39 40 This sample uses the Gradle build system.
