Unsupported Texture width

[orkshaman]

Hello world example gives "Unsupported Texture width" error on emulator and on HTC phone, but on my LG P500 all works ok.

Code Select Expand

Texture texture = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.icon)), 64, 64));
TextureManager.getInstance().addTexture("texture", texture);

TextureManager.getInstance().addTexture("0", new Texture(getResources().getDrawable(R.raw.zero),true));

Texture size is 64x64 not 96x96

Depending on the devices and on the Android version, bitmaps from drawable get scaled when loading. The HelloWorld example uses it's own icon as a texture. Just put some other fitting bitmap in raw and load that instead.

[orkshaman]

EgonOlsen, but icon loads properly. Error comes when it tries to load R.raw.zero texture.

[EgonOlsen]

That's because you are loading it as a Drawable. Don't do that. Drawables will be scaled by Android under some circumstances. Use either bitmaps or an inputstream instead.

Thank you EgonOlsen.
