Which device you’re using? What happens if you’ll save file to PNG?

I have follow the source code and know the reason that the file path is not correct. the CCRenderTexture will add a getWriablePath to the file path… I want the path is : /mnt/data/xxx will be changed to /mnt/data//data/data/xxx so I modify the method and get the right path ,then it worked!
