Note that in Android, Uri's are different from Java URI's. Here's how to avoid using hardcoded strings, and at the same time, create a Uri with just the path portion of the http URL string encoded to conform to RFC2396:

Sample Url String:

String thisUrl = "http://lapi.transitchicago.com/api/1.0/ttarrivals.aspx?key=[redacted]&mapid=value"

method:

private Uri.Builder builder;
public Uri getUriFromUrl(String thisUrl) {
    URL url = new URL(thisUrl);
    builder =  new Uri.Builder()
                            .scheme(url.getProtocol())
                            .authority(url.getAuthority())
                            .appendPath(url.getPath());
    return builder.build();
}

To handle query strings you will need to parse the url.getQuery() as described here and then feed that into builder. appendQueryParameter().
