Answer 1

i solved it my self... This code will get you an auth-token, with the username and password you provide, and then that token will be put in the header to get data from the server...

public void vollyRequestGetAuthToken()
{
    RequestQueue queue  = Volley.newRequestQueue(this);
    StringRequest request =  new StringRequest(Request.Method.POST  , "https://example.com/get-auth-token/", new Response.Listener<String>() {

        @Override

    public void onResponse(String response) {
        Toast.makeText(MainActivity.this, "RESPONSE: " + response, Toast.LENGTH_SHORT ).show();
        System.out.println("RESPONSE:          >>> " + response + "<<<");
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Toast.makeText(MainActivity.this, "ERROR: " + error, Toast.LENGTH_SHORT ).show();
    }
}) {
    @Override
    protected Map<String,String> getParams(){
        Map<String,String> params = new HashMap<String, String>();
        params.put("username","*****");
        params.put("password","*****");
        return params;
    }
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        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)));
        params.put("username" , "*****" );
        params.put("password" , "*****" );
        return params;
    }
};
    queue.add(request);
}

and now when you have the auth-token, use the following code to send auth-token to get data

@Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                HashMap<String, String> headers = new HashMap<String, String>();
                headers.put("Authorization", "Token <token>");
                return headers;
            }

Answer 2

This is caused when the request is declined/blocked from the API End Point. The reason could be a malformed request for that,

• Check your request type [GET/POST/ANY OTHER]
• Check the request Header and Body
