Remarks
Handle onto a raw buffer that is being managed by the screen compositor.
A Surface is generally created by or from a consumer of image buffers (such as a android.graphics.SurfaceTexture, android.media.MediaRecorder, or android.renderscript.Allocation), and is handed to some kind of producer (such as android.opengl.EGL14#eglCreateWindowSurface(android.opengl.EGLDisplay,android.opengl.EGLConfig,java.lang.Object,int[],int) OpenGL, android.media.MediaPlayer#setSurface MediaPlayer, or android.hardware.camera2.CameraDevice#createCaptureSession CameraDevice) to draw into.
<strong>Note:</strong> A Surface acts like a java.lang.ref.WeakReference weak reference to the consumer it is associated with. By itself it will not keep its parent consumer from being reclaimed.
