Android: The *_from_file() functions now check the assets folder. Also try all the loadable file extensions that I am aware of for images. Not sure if I should try absolute paths too or just leave it only assets. Create an "assets" folder under main and put file.png and folder.png in. Create a subfolder "image" and put test.png in. This will create an app with the required images.
