How to create a android.net.Uri from a java.net.URL?

Question

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 URL, or a ByteArrayInputStream I create from the byte[], etc). However, I cannot figure out how this is supposed to be done.

So, is there anyway to create a Uri from data obtained from a URL without first writing the data to a local file?

Answer 1

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

Example:

URL url = new URL("http://www.google.com"); //Some instantiated URL object URI uri = url.toURI(); 

Make sure to handle relevant exception, such as URISyntaxException.

Answer 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.Builder b = 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); }  String url = b.build().toString();
