@Anushree278 Sorry for the late reply, here is question about how to load texture properly. If correctly-loaded Bitmap object pass into TextureHelper.updateBitmap then texture will update. Also check OpenGL samples with texture processing, maybe your OpenGL build and target device gives inappropriate results.
