Hey thanks for the reply :)
I figured out that it was on certain builds of android even when you have
images that are in the power of two, once you pull them from a stream and
pass them by reference some how theres a chance that they will be resized.
I went through and made sure that anywhere I was making a copy by reference
I used
BitmapFactory.Options ops = new BitmapFactory.Options();
ops.inScaled = false;
And this prevents the system from messing with the images.

Well there's an API calls that can easily load several different standard
graphics file formats, for example:
//Get the texture from the Android resource directory
InputStream is =
context.getResources().openRawResource(R.drawable.onlylowercasefilenameshere);
Bitmap bitmap = null;
try {
//BitmapFactory is an Android graphics utility for images
bitmap = BitmapFactory.decodeStream(is);
} finally {
//Always clear and close
try {
is.close();
is = null;
} catch (IOException e) {
}
}
If you are concerned about people replacing your image files with
something else, then you can make that more difficult by doing some sort of
checksum before using them. Otherwise, if you are concerned with people
getting exact copies of standard image files, I don't know what to tell
you. I wonder if anybody can suggest an efficient solution for that?

Im using min3d to draw 3d boxes and Im applying textures to them in the
updateScene method which works great on some devices and on others the
textures wont load. Ive tried debugging by turning on the
glflags but I dont see any errors what so ever. Ive done a lot of reading
and googling the past two days on the matter and it looks like theres no
real good answer on why opengl would work on one device and not on another.
So far Ive tried making sure the images were in the power of two and that
wasnt it.
The way that Im accessing the images to use as bitmaps is by pulling
bitmaps from images that are stored on the devices internal file system. I
read in one thread some where that instead of decoding a file to make a
bitmap
you could turn the file into a stream and then decode that as a bitmap
and that would work but I havent even tried doing that since I spent most
of my time trying to debug to find any nullpointers or anything. At first I
thought I had found some null textures but they were just textures that
hadnt initialized yet.
So as this is a common problem on android I was hoping others could help
me out by shedding some light on how they tackled the problem of opengl
textures not loading on certain devices.
