Try to disable glBindTexture(), for use this call you have forgotten
two things:
1) gl.glEnable(GL11.GL_TEXTURE_2D); // enable
2) GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, image_data, 0); //
set data
try to remove the call for see if these things are the problem or not.
I hope it solve problem, bye
