How do I use Http Digest Auth with volley on Android

I want to use Http Digest with Volley. So far I have used the following code:

@Override
public Map<String, String> getHeaders() throws AuthFailureError {

    HashMap<String, String> params = new HashMap<String, String>();
    String creds = String.format("%s:%s","admin","mypass");
    String auth = "Digest " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
    params.put("Authorization", "Digest " +auth);
    return params;

}

So far I get a response from server as wrong credentials which means that authentication is working but only wrong credentials are getting passed. But my credentials are right.

You use Base64 encoding which is fine for Basic Auth but this is not how digest works. Digest & Basic Auth specs can be found here: https://www.rfc-editor.org/rfc/rfc2617

the newer Digest Specs can be found here: https://www.rfc-editor.org/rfc/rfc7616

And nice extra explanation on wikipedia here: https://en.wikipedia.org/wiki/Digest_access_authentication

For Volley implementation of Digest Auth you can use: http://www.java2s.com/Open-Source/Android_Free_Code/Framework/platform/com_gm_android_volleyHttpDigestStack_java.htm

You will just need to pass this http stack when you create your Network which you then use to create your RequestQueue:

    RequestQueue requestQueue;
    requestQueue = new RequestQueue(
            new DiskBasedCache(rootDir),
            new BasicNetwork(new HttpDigestStack())
    );
    requestQueue.start();
