Part of my texture loading code looks like this:
final Bitmap bitmap =
BitmapFactory.decodeResource(context.getResources(), resId);
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);
bitmap.recycle();
Following lines should be somewhere in initialization:
// Blending Function For Translucency Based On Source Alpha Value
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE);
gl.glEnable(GL10.GL_BLEND);
