Question

i want to load a 3d .obj file in live wallpaper and animate it. i use RAJAWALI library to load it. the problem is that the the 3d obj file is load and animate successfully but Loading background image are not loaded in some android devices. code is follow:

protected void initScene() {


    DirectionalLight localDirectionalLight = new DirectionalLight(0.0F, 0.6F, 0.4F);
localDirectionalLight.setPower(3.0F);
PointLight mLight = new PointLight();
mLight.setPosition(0, 0, 0);
mLight.setPower(13);
Plane plane = new Plane(70, 70, 1, 1, 1);
plane.addLight(mLight);
plane.setMaterial(new SimpleMaterial());
plane.addTexture(mTextureManager.addTexture(BitmapFactory.decodeResource(mContext.getResources(), R.drawable.pozadina)));  
addChild(plane);    
plane.setZ(10);

    try
    {
      ObjParser localObjParser = new ObjParser(this.mContext.getResources(), this.mTextureManager, R.raw.allah);
      localObjParser.parse();
      this.strela = localObjParser.getParsedObject();
      this.strela.addLight(localDirectionalLight);
      if (this.tekstura == null)
      {
        BitmapFactory.Options localOptions2 = new BitmapFactory.Options();
        localOptions2.inPurgeable = true;

        this.strela.setColor(Color.WHITE);
      }
      this.strela.setScale(2.0F);
      addChild(this.strela);
      this.mCamera.setPosition(0.0F, 0.0F, -50.0F);
      this.mCamera.setFarPlane(1000.0F);
      Number3D localNumber3D = new Number3D(0.0F, 1.0F, 0.0F);
      localNumber3D.normalize();
      this.mAnim = new RotateAnimation3D(localNumber3D, 360.0F);
      this.mAnim.setDuration(10000L);
      this.mAnim.setRepeatCount(-1);
      this.mAnim.setTransformable3D(this.strela);

      return; 
    }
    catch (Exception localException)
    {
      while (true)

This is tested and working on Galaxy S3. So it should work for you as well. I use it in my wallpapers. Try this:

    SimpleMaterial localSimpleMaterial = new SimpleMaterial();
    Bitmap localBitmap = BitmapFactory.decodeResource(this.mContext.getResources(), R.drawable.image);
    localSimpleMaterial.addTexture(this.mTextureManager.addTexture(localBitmap));
    Plane localPlane = new Plane(10.0F, 10.0F, 1, 1);
    localPlane.setRotZ(-90.0F);
    localPlane.setScale(3.7F);
    localPlane.setPosition(0.0F, 0.0F, 10.0F);
    localPlane.setMaterial(localSimpleMaterial);
    addChild(localPlane);

Just make sure that your image is power of two, i.e., 256x256, 512x512, etc. Let me know how it works for you.

Edit: Also make sure you import rajawali.primitives not rajawali.math

i will check it. if it work for me then i will mark the answers as correct. — ibad ur rahman, Apr 26 '13 at 10:13

Is the issue solved? What are those devices on which the plane is not rendered? Are those Samsung? Also please tell me is it rendered in grey color or not rendered at all?

I am asking because I ran into same problem where the solution was to adjust the mip-mapping. It took time as I was a beginner then, but there was a very simple solution:

Textures are not displayed on the sphere for Samsung Galaxy SL
