Error loading textures from resources - easy fix!

[wernerlaurence]

Hello,

Firstly, thank you to everyone involved in this project - amazing work!

I had a problem getting the lesson 08 example working, kept getting an NullPointerException on loading the resource:

(...)
public void loadGLTexture(GL10 gl, Context context) {
//Get the texture from the Android resource directory
InputStream is = context.getResources().openRawResource(l.werner.livewallpaper.hypnoclockgl.R.drawable.nehe_android);
Bitmap bitmap = null;
try {
//BitmapFactory is an Android graphics utility for images
bitmap = BitmapFactory.decodeStream(is);

        } finally {
                //Always clear and close
                try {
                        is.close();
                        is = null;
                } catch (IOException e) {
                }
        }

(...)

I found that the easiest way to fix this nullpointerexception is to modify the constructor in MyWallpaperService.MyEngine to include

renderer.setContext(getApplicationContext());

Full method:
public MyEngine()
{
super();
// handle prefs, other initialization
renderer = new MyRenderer();
setRenderer(renderer);
setRenderMode(RENDERMODE_CONTINUOUSLY);
renderer.setContext(getApplicationContext());
}

Anyways, hope this helps someone!

Thanks again to Mark F Guerra and Robert Green!
