Android: ScreenShot / ScreenCapture Code
Con estas líneas podemos hacer una captura de pantalla de nuestra aplicación Android. En este ejemplo la captura se guarda en la sdCard.
Del codigo, hay que tener en cuenta que se hace la captura de un View (viewToBeCaptured), que le tenemos que asignar el layout que queramos capturar.
