Android Opengl ES: GLUtils.glTexImage2D calls GL_INVALID_ENUM

Question

I am trying to make a simple textured square on Android 2.2 using GLSurfaceView . I upload a BMP image (128x128) using BitmapFactory.decodeResource() - this seems to work. But whenever I try to put this bitmap into an OpenGL texture using GLUtils.glTexImage2D , I get an OpenGL error: glGetError() returns 1280, GL_INVALID_ENUM . What am I doing wrong? This is the code for my Renderer:

 public class MyRenderer implements GLSurfaceView.Renderer { Context context; int texId; public MyRenderer(Context c) { this.context = c; } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { gl.glEnable(GL10.GL_TEXTURE_2D); this.texId = loadTexture(gl); } int loadTexture(GL10 gl) { int[] tmp = new int[1]; gl.glGenTextures(1, tmp, 0); int id = tmp[0]; Bitmap bmp = BitmapFactory.decodeResource(this.context.getResources(), R.drawable.myimage); gl.glGetError(); GLUtils.texImage2D(id, 0, bmp, 0); int err = gl.glGetError(); if (err != 0) { // err == 1280, prints "invalid enum": System.err.println(GLU.gluErrorString(err)); } return id; } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); GLU.gluOrtho2D(gl, 0, width, height, 0); gl.glMatrixMode(GL10.GL_MODELVIEW); gl.glLoadIdentity(); } @Override public void onDrawFrame(GL10 gl) { // ... } } 

Answer 1

It should probably be something like this:

 gl.glBindTexture(GL10.GL_TEXTURE_2D, id); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bmp, 0);
