Throw the exceptions from the getBitmap method instead and let the client (Activity) handle the exceptions, in this case either you receive a Bitmap or an exception and can skip the return null bitmap and do the according "default bitmap loading" in the catch blocks, for the exception/error case instead (since this is the null case now).

public Bitmap getBitmap(final String src) throws FileNotFoundException,
        OutOfMemoryError, IOException, MalformedURLException {
    URL url = new URL(src);
    URLConnection connection = url.openConnection();
    InputStream input = connection.getInputStream();
    return BitmapFactory.decodeStream(input);
}
