Hi! I have a canvas object, without a paint method, on which video is continously drawn by an underlying native DLL, via JNI interfaces. My problem is: when I click a "pause" button, the video stream is paused, and there is no more trasmission to the canvas. naturally, as soon as repaint is needed, the content immediately disappears until I click a "resume" button, that restores the streaming from the JNI, and it is shown on the canvas. My question is: How can I "copy" the content when the "pause" is pressed and show it continously on the canvas, until a "resume" is pressed and the stream continues?    More>>
