Hi,
I am using the code below to attempt to display a bitmap, which will
act as the splash screen for a little android pacman game im creating
(learning may aswell be fun). The problem is that the JPG file is not
being displayed. I can see no reason why this is happening.
I've done a toString in the Log for mPacManMenImg, so it seems like
the following line:
mPacManMenuImg = BitmapFactory.decodeResource(res,
R.drawable.pacman_thumb);
is correctly returning a reference to the Bitmap.
I have checked and the image is listed as pacman_thumb in drawable, on
R.java.
Any ideas? (code follows)
Thanks
