You can use droidQuery to perform async restful requests with authentication. Look at the AjaxOptions documentation for adding a username and password to a request. – Treasatreason

Basic Http authorization looks like the next header:

Authorization: Basic dXNlcjp1c2Vy

where dXNlcjp1c2Vy is your user:password string in Base64 format, word "Basic" means the authorization type.

So you need to set the request header named Authorization.

To do this you need to override getHeaders method in your request class

The code will look like this:

@Override
public Map<String, String> getHeaders() {
    Map<String, String> params = new HashMap<String, String>();
    params.put(
            "Authorization",
            String.format("Basic %s", Base64.encodeToString(
                    String.format("%s:%s", "username", "password").getBytes(), Base64.DEFAULT)));
    return params;
}

Extend the volley request class of your choice and overwrite getHeaders(). Return a Map with the authentication information there (headers.put('Authorization', 'authinfo...'))
