lazy loading of textures

In VideoPlack sample we are loading textures in onCreate method with following method before updateApplicationStatus(APPSTATUS_INIT_APP);

private void loadTextures()

    {

        mTextures.add(Texture.loadTextureFromApk("VuforiaSizzleReel_1.png",

                getAssets()));

        mTextures.add(Texture.loadTextureFromApk("VuforiaSizzleReel_2.png",

                getAssets()));

        mTextures.add(Texture.loadTextureFromApk("play.png",

                getAssets()));

        mTextures.add(Texture.loadTextureFromApk("busy.png",

                getAssets()));

        mTextures.add(Texture.loadTextureFromApk("error.png",

                getAssets()));

    }

What if I want to load textures after downloading them from internet? What should I do? If I simply add texture to mTextures array then it is not loaded since we have to load textures in cpp file as well.
