Basic authentication to access assembla rest apis from android

Question

I want to use assembla apis from android environment for my project. I am trying to do basic authentication as follow :

String authentication = "username:password";
String encoding = Base64.encodeToString(authentication.getBytes(), 0);    

     URL url = new URL("https://www.assembla.com/");

        conn = (HttpURLConnection) url.openConnection();

        conn.setRequestMethod("GET");

        conn.setRequestProperty("Authorization", "Basic " + encoding);
        conn.setDoOutput(true);

        conn.connect();
        System.out.println(conn.getResponseCode());

        System.out.println(conn.getResponseMessage());

I am getting 400 and Bad Request in output. is there something wrong with URL that i am using or some other thing is going wrong?

It looks like the question was answered here. You need to use Base64.NO_WRAP flag when encoding username-password pair:

String encoding = Base64.encodeToString(authentication.getBytes(), Base64.NO_WRAP);

By default the Android Base64 util adds a newline character to the end of the encoded string. This invalidates the HTTP headers and causes the "Bad request".

The Base64.NO_WRAP flag tells the util to create the encoded string without the newline character thus keeping the HTTP headers intact.
