GoogleGlass : Add image in background : unsupporte

问题:

I have a problem when i try to set an image URL on a Card.

Here is the error log : unsupported image scheme: http

com.example.cupofnewsglass.MainActivity.processFinish(MainActivity.java:112)

Here is my code :

// Get img of article, it return an string like : http://img.
String imgUrl = articles.get(i).getImage();
// Get Publication Date
String pubDate = createDateForGlass(articles.get(i).getPubDate());
// Convert imgUrl to an Uri
Uri imgUri = Uri.parse(imgUrl);
// Set main text in card
card.setText(title + " ago");
// Set Footer text in card
card.setFootnote(pubDate);
// Image will be in Fullscreen mode
card.setImageLayout(Card.ImageLayout.FULL);
// Set background image in card
card.addImage(imgUri);

This is working as intended, the only supported schemes for the Card builder class are file and android.resource.

This feature request is tracking support for web images in the Card builder class.
