As i have came here looking for an Android-Java-Answer i am going to do a short summary:

1. Use java.net.Authenticator as shown by James van Huis
2. Use Apache Commons HTTP Client, as in this Answer
3. Use basic java.net.URLConnection and set the Authentication-Header manually like shown here

If you want to use java.net.URLConnection with Basic Authentication in Android try this code:

URL url = new URL("http://www.mywebsite.com/resource");
URLConnection urlConnection = url.openConnection();
String header = "Basic " + new String(android.util.Base64.encode("user:pass".getBytes(), android.util.Base64.NO_WRAP));
urlConnection.addRequestProperty("Authorization", header);
// go on setting more request headers, reading the response, etc
