MediaProjection

public final class MediaProjection
extends Object

java.lang.Object
↳	android.media.projection.MediaProjection

A token granting applications the ability to capture screen contents and/or record system audio. The exact capabilities granted depend on the type of MediaProjection.

A screen capture session can be started through MediaProjectionManager#createScreenCaptureIntent. This grants the ability to capture screen contents, but not system audio.

Summary

Nested classes
`class`	`MediaProjection.Callback` Callbacks for the projection session.

Public methods
`VirtualDisplay`	`createVirtualDisplay(String name, int width, int height, int dpi, int flags, Surface surface, VirtualDisplay.Callback callback, Handler handler)` Creates a `VirtualDisplay` to capture the contents of the screen.
`void`	`registerCallback(MediaProjection.Callback callback, Handler handler)` Register a listener to receive notifications about when the `MediaProjection` changes state.
`void`	`stop()` Stops projection.
`void`	`unregisterCallback(MediaProjection.Callback callback)` Unregister a MediaProjection listener.

`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

                int height, 
                int dpi, 
                int flags, 
                Surface surface, 
                VirtualDisplay.Callback callback,

`height`	`int`: The height of the virtual display in pixels. Must be greater than 0.
`dpi`	`int`: The density of the virtual display in dpi. Must be greater than 0.
`flags`	`int`: A combination of virtual display flags. See `DisplayManager` for the full list of flags.
`surface`	`Surface`: The surface to which the content of the virtual display should be rendered, or null if there is none initially. This value may be `null`.
`callback`	`VirtualDisplay.Callback`: Callback to call when the virtual display's state changes, or null if none. This value may be `null`.
`handler`	`Handler`: The `Handler` on which the callback should be invoked, or null if the callback should be invoked on the calling thread's main `Looper`. This value may be `null`.
