  You can set the Texture of the Image2D using the Image2D setImage(Texture) API.

  To create a Texture, you can use the TextureBuilder API. 
  For example:

        mBitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), Uri.parse(mUrl));
          ...
          mBitmap = BitmapUtils.flip(mBitmap);
  
          int[] data = BitmapUtils.bitmapToPixelArray(mBitmap);
          data = BitmapUtils.swizzleARGBToRGBA(data);
  
          ByteBuffer byteBuffer = ByteBuffer.allocate(data.length * 4);
          IntBuffer intBuffer = byteBuffer.asIntBuffer();
          intBuffer.put(data);
  
          GraphicsFormat format = GraphicsFormat.GraphicsFormatR8G8B8A8_UNORM;
          BitmapImage images[] = {
                  new BitmapImage(mBitmap.getWidth(), mBitmap.getHeight(),
                          format, byteBuffer.array(), "AlbumArt")
          };
  
          TextureBuilder builder = new TextureBuilder()
                  .setName("AlbumArtTexture")
                  .setWidth(mBitmap.getWidth())
                  .setHeight(mBitmap.getHeight())
                  .setImages(images)
                  .setFormat(format);
  
          mTexture = builder.build(mDomain);

  If you need to use URI such as "content://" with Kanzi, you need to introduce a custom protocol handler. 
  
  The BitmapUtils class can be found here:

  As well as the 
  Android\Resource_import project
