Turning a string into a Uri in Android
Uri.parse(STRING);
See doc:
String: an RFC 2396-compliant, encoded URI
Url must be canonicalized before using, like this:
Uri.parse(Uri.decode(STRING));
Uri myUri = Uri.parse("http://www.google.com");
Here's the doc http://developer.android.com/reference/android/net/Uri.html#parse%28java.lang.String%29
