Android Drawable Images from URL

Question

I am presently using the following peice of code to load in images as drawable objects form a URL.

Drawable drawable_from_url(String url, String src_name) throws java.net.MalformedURLException, java.io.IOException {
        return Drawable.createFromStream(((java.io.InputStream)new java.net.URL(url).getContent()), src_name);

    }

This code works exactly as wanted, but there appears to be compatibility problems with it. In version 1.5, it throws a FileNotFoundException when I give it a URL. In 2.2, given the exact same URL, it works fine. The following URL is an sample input I am giving this function.

How would I load in images in a way that is compatible across the board from a URL?

Answer 1

I'm not sure, but I think that Drawable.createFromStream() is more intended for use with local files rather than downloaded InputStreams. Try using BitmapFactory.decodeStream(), then wrapping the return Bitmap in a BitmapDrawable.

Answer 2

Solved it myself. I loaded it in as a bitmap using the following code.

Bitmap drawable_from_url(String url) throws java.net.MalformedURLException, java.io.IOException { Bitmap x;

HttpURLConnection connection = (HttpURLConnection)new URL(url) .openConnection();
connection.setRequestProperty("User-agent","Mozilla/4.0");

connection.connect();
InputStream input = connection.getInputStream();

x = BitmapFactory.decodeStream(input);
return x;

}

It was also important to add in the user agent, as googlebooks denies access if it is absent
