One way to do this is to upload “logo” as an asset, then:

Get the Bitmap from the asset:

If the icon is stored in the extension, you can use Form’s openAssetForExtension in combination with MediaUtil’s getBitmapDrawable to obtain a BitmapDrawable. Extensions do not support using Android-style resource files at this time.
