How To Create A Android.net.uri From A Java.net.url?

I would like to use intent.setData(Uri uri) to pass data obtained from a URL. In order to do this, I need to be able to create a Uri from a URL (or from a byte[] I read from the U

Solution 1:

Use URL.toURI() (Android doc) method.

Example:

URLurl=newURL("http://www.google.com"); //Some instantiated URL objectURIuri= url.toURI();

Make sure to handle relevant exception, such as URISyntaxException.

Solution 2:

I think your answer can be found from here..

Uri.Builder.build() works quite well with normal URLs, but it fails with port number support.

The easiest way that I discovered to make it support port numbers was to make it parse a given URL first then work with it.

Uri.Builderb= Uri.parse("http://www.yoursite.com:12345").buildUpon();

b.path("/path/to/something/");
b.appendQueryParameter("arg1", String.valueOf(42));

if (username != "") {
  b.appendQueryParameter("username", username);
}

Stringurl= b.build().toString();

From How to create a Uri from a URL?

Uriuri=  Uri.parse( "http://www.facebook.com" );

Solution 4:

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:

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

method:

privateUri.Builder builder;
publicUrigetUriFromUrl(String thisUrl) {
    URL url = newURL(thisUrl);
    builder =  newUri.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().

Solution 5:

URI uri = null;
URL url = null;

// Create a URItry {
    uri = new URI("www.abc.com");
} catch (URISyntaxException e) {
}

// Convert an absolute URI to a URLtry {
    url = uri.toURL();
} catch (IllegalArgumentException e) {
    // URI was not absolute
} catch (MalformedURLException e) {
}

// Convert a URL to a URItry {
    uri = new URI(url.toString());
} catch (URISyntaxException e) {
}
