Hi,  I had change my code to this:
GIFHandlerJPCTAE.addTexture( "Bottom", activity.getResources().openRawResource( R.raw.twobuf ), true );
and no error. But after i installed it into my phone, the app close unexpectedly.
Why is this happen?

Thanks.

Below is my code in ImageTargetsRenderer.java, but I have an error :- The method getResources() is undefined for the type ImageTargetsRenderer

Code: [Select]

public ImageTargetsRenderer(ImageTargets activity){
        this.mActivity = activity;
        TextureManager.getInstance().flush();
        world = new World();
world.setAmbientLight(20, 20, 20);

sun = new Light(world);
sun.setIntensity(250, 250, 250);

// Create a red texture, for debugging purposes (TODO: remove)
Texture texture = new Texture( 8, 8, new RGBColor( 255, 0, 0) );
TextureManager.getInstance().addTexture( "texture", texture );

// Load some animated GIF files to use:
GIFHandlerJPCTAE.addTexture( "Front", getResources().openRawResource( R.raw.twobuf ), true );

plane = Primitives.getPlane(20, 30);
plane.calcTextureWrapSpherical();
plane.setTexture("texture");
plane.strip();
cube.build();

world.addObject(plane);

/* cube = Primitives.getCube(100);
cube.calcTextureWrapSpherical();
cube.setTexture("texture");
cube.strip();
cube.build();

world.addObject(cube);*/

        cam = world.getCamera();
        //cam.moveCamera(Camera.CAMERA_MOVEOUT, 50);
        cam.lookAt(plane.getTransformedCenter());

SimpleVector sv = new SimpleVector();
sv.set(cube.getTransformedCenter());
sv.y -= 100;
sv.z -= 100;
sun.setPosition(sv);
MemoryHelper.compact();

Hi, I had read this: http://www.paulscode.com/forum/index.php?topic=9.0 , this is awesome. Can this be implement into AR world. I want to render a gif on a plane on a marker.
