Hi I am also currently trying to get MipMaps to work and eventually this is the thread that pops up several times in the search ^^'.
The problem I have with your posted solution, it does not work for me. As soon as I try it your way I do not get any texture at all. It just stays white. What could be the problem, as it should be the normal way to to MipMaps by adding the new images to the according level. But as soon as I add a second level it stays white. I define gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); before, but still it won't work. Does anybody has a solution or a hint what could help here? Thanks in advance.
