textureid Draw the vertices as triangles gl.glDrawElements GL10.GL_TRIANGLES indices.length GL10.GL_UNSIGNED_BYTE indexBuffer Pop the matrix back to where we left it gl.glPopMatrix Disable the client state before leaving gl.glDisableClientState.. to glVertexPointer and glTexCoordPointer above. Also here is the initialization of vertexBuffer textureBuffer and indexBuffer ByteBuffer byteBuf ByteBuffer.allocateDirect vertices.length 4 byteBuf.order ByteOrder.nativeOrder vertexBuffer byteBuf.asFloatBuffer.. ByteOrder.nativeOrder textureBuffer byteBuf.asFloatBuffer textureBuffer.put texture textureBuffer.position 0 indexBuffer ByteBuffer.allocateDirect indices.length indexBuffer.put indices indexBuffer.position 0 loadGLTextures gl this.context ..
