[android-developers] Re: Multiple Texture Issues on OLGES20

Steve,

Have you tried the following?

GLES20.glActiveTexture(GLES20.GL_TEXTURE0);
GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textures[0]);
GLES20.glActiveTexture(GLES20.GL_TEXTURE1);
GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textures[1]);

I think that's what you're missing.
