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?
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.
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(); Source : http://twigstechtips.blogspot.com/2011/01/android-create-url-using.html
yourUrlVariable.toString() instead.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().
try { uri = new URI(url.toString()); } catch (URISyntaxException e) { }
