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?
