1 2Android ScreenCapture Sample 3=================================== 4 5This sample demonstrates how to use Media Projection API to capture device screen in real time and 6show it on a SurfaceView. 7 8Introduction 9------------ 10 11Media Projection API lets you capture the current screen through Surface. 12 13To start media projection, you need to get an instance of [MediaProjection][1]. For this, you have 14to call startActivityForResult with an Intent from 15[MediaProjectionManager.createScreenCaptureIntent()][2]. This shows a confirmation dialog to the 16user. When user confirms it, you will get a result code and data in onActivityResult, so pass those 17to [getMediaProjection][3]. 18 19Once you get a MediaProjection, use [createVirtualDisplay][4] and bind it to a Surface. 20 21[1]: https://developer.android.com/reference/android/media/projection/MediaProjection.html 22[2]: https://developer.android.com/reference/android/media/projection/MediaProjectionManager.html#createScreenCaptureIntent() 23[3]: https://developer.android.com/reference/android/media/projection/MediaProjectionManager.html#getMediaProjection(int, android.content.Intent) 24[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) 25 26Pre-requisites 27-------------- 28 29- Android SDK 27 30- Android Build Tools v27.0.2 31- Android Support Repository 32 33Screenshots 34------------- 35 36<img src="screenshots/main.png" height="400" alt="Screenshot"/> 37 38Getting Started 39--------------- 40 41This sample uses the Gradle build system.
