Nexus S with Android 4.0.3 is OK.
but galaxy nexus is failed.(all raw data is zero)
Can you tell me how to get fb0 on galaxy
the reason is that:the frame buffer supports page-flip(double
framebuffer).so you can't get the right address.

I study source code of screencap, and it uses
ScreenshotClient class

screenshot that

I suggest you use what I told you. Direct access to the frame buffer has
been a hack that kind-of works; it is not the correct way to take a screen
shot, and as of 3.0 the command for taking a screen shot and internal Java
implementation use a different mechanism that always qworks.

as far as I remember you need a rooted phone to have access to fb0
