How does one use Basic Authentication with Volley on Android?

I'm looking through examples and code but I don't see anything implemented. Is this possible at this stage?

For a proxy authorization (like squid) use this header :

String credentials = proxyUsername + ":" + proxyPassword;
String auth = "Basic "  + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);                
headers.put("Proxy-Authorization", auth);

Yes it's possible. You need to override Request.getHeaders(). I'm lazy and I used HttpHeaders and HttpAuthentication from Spring for Android but you can just build the auth header and return it from the method. From getHeaders() you can return the auth header for basic auth. This is a sample request with basic auth. 

public class GetUser extends Request<User> {

    private static final String TAG = GetUser.class.getName();

    private Response.Listener<User> mListener;
    private ObjectMapper mMapper = new ObjectMapper();

    public GetUser(Response.ErrorListener errorListener, Response.Listener<User> listener){
        super(Method.GET, PoisUtils.BASE_URL + "/users", errorListener);

        mListener = listener;
    }

    @Override
    protected Response<User> parseNetworkResponse(NetworkResponse response) {
        String jsonString = new String(response.data);
        try {
            User result = mMapper.readValue(jsonString, User.class);
            return Response.success(result, getCacheEntry());
        } catch (IOException e) {
            Log.d(TAG, e.getMessage());
        }
        return null;
    }

    @Override
    protected void deliverResponse(User response) {
        mListener.onResponse(response);
    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        return AuthUtils.buildAuthHeaders().toSingleValueMap();
    }
}

And here is how I build the auth headers

public static HttpHeaders buildAuthHeaders(){

    if(UserUtils.isUserLogged()){
        HttpHeaders requestHeaders = new HttpHeaders();
        User user = PoisApplication.get().getUser();

        HttpAuthentication auth = new HttpBasicAuthentication(
                user.getUsername(), user.getPassword());
        requestHeaders.setAuthorization(auth);

        return requestHeaders;
    }
    return null;
}

For those who don't want to use Spring for Android just for that, here's how to do it.

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    HashMap<String, String> params = new HashMap<String, String>();
    String creds = String.format("%s:%s","USERNAME","PASSWORD");
    String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
    params.put("Authorization", auth);
    return params;
}

Note that you may have to use Base64.NO_WRAP instead of Base64.DEFAULT for this to work. As pointed in the comments.
