Android NTLM getting HTTP/1.1 401 Unauthorized

Question

I am try to get data from share point server. Following is my code.

    DefaultHttpClient httpclient = new DefaultHttpClient();

    httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
    httpclient.getCredentialsProvider().setCredentials(new AuthScope("masconsult.eu", -1),
            new NTCredentials(username, password, "", ""));
    HttpGet httpGet = new HttpGet(webserviceUrl);
    httpGet.addHeader("Content-type", "application/json");
    httpGet.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
    // HttpResponse response="";
    String responseXML = "";
    HttpResponse response = httpclient.execute(httpGet);
    response.getStatusLine().getReasonPhrase();
    responseXML = EntityUtils.toString(response.getEntity());
    Toast.makeText(this, responseXML, Toast.LENGTH_LONG).show();

I have got response HTTP/1.1 401 Unauthorized. Even I have added all right credential. In Chrome browser It working fine with same credential. plz suggest me any change in code.

You might not need any changes in your code. In IE, under Tools > Advanced, ensure that you have enabled "Integrated Windows Authentication", under Tools > Security > Local Intranet zone > Sites > Advanced, ensure the target web site is listed. Clear cookies and restart IE. — T-Heron, Nov 23 '16 at 12:19

Now its working. I modified my code with headers.

 DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
    httpclient.getCredentialsProvider().setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), new NTCredentials(username, password, "", ""));
    HttpGet httpGet = new HttpGet(webserviceUrl);
    httpGet.addHeader("accept", "application/json;odata=verbose");
    httpGet.addHeader("content-Type", "application/json;odata=verbose");
    httpGet.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
    HttpResponse response = httpclient.execute(httpGet);
    System.out.println("Responseeee" + response.getStatusLine());
    responseXML = EntityUtils.toString(response.getEntity());
    new JSONObject(responseXML).toString();
