How does one use Basic Authentication with Volley on Android?

by

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.
