Dear Sir,
I want to do screenshot on Samsung Galaxy Nexus(TI chip, ICS). I tried the method of reading screen data from framebuffer ( /dev/graphics/fb0 ), but the data was totally black. Then I used the shell command "adb pull /dev/graphics/fb0 D:\test.rgb", got the same result.
The method I wrote above normally works ok (on Moto ME863, TI chip, Gingerbread), so I want to ask that is there any difference about framebuffer between the two devices? How can I get screen data on Samsung Galaxy?
Thank you very much.
BR,
Qiao
