Android HTTP Authentication error

Question

final HttpClient hClient = new DefaultHttpClient();
final HttpPost hPost = new HttpPost(
        "http://xxx.xxx");
try {
    hPost.setHeader("Accept", "application/json");
    hPost.setHeader("Content-type",
            "application/json");
    hPost.setEntity(new StringEntity(JSON));
    // execute request
    final HttpResponse response = hClient
            .execute(hPost);
    final HttpEntity entity = response.getEntity();

Android returns 05-16 20:02:52.784: W/DefaultRequestDirector(15642): Authentication error: Unable to respond to any of these challenges: {} and I don't know how to fix it. Where is the problem and how can I fix it?

Answer 1

Try setting the Http parameters as following:

HttpParams myParams = new BasicHttpParams();

HttpConnectionParams.setSoTimeout(myParams, 10000);
HttpConnectionParams.setConnectionTimeout(myParams, 10000); // Timeout

DefaultHttpClient httpClient = new DefaultHttpClient(myParams);

For the http post and response you can try the following code. Kindly customize according to your needs (for example set your string parameters)

HttpResponse response;
httpClient.getParams().setParameter("Your String", "YourStringValue");
localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(YOurURL);

Log.e("URL", URL); //just to check 

httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY,CookiePolicy.RFC_2109);

StringEntity tmp = null;

httpPost.setHeader("Accept", "application/json");

tmp = new StringEntity(inputJObject.toString(), "UTF-8");

httpPost.setEntity(tmp);

response = httpClient.execute(httpPost, localContext);


Log.i(TAG, response.getStatusLine().toString()); // Examine the response status


HttpEntity entity = response.getEntity();  // Get hold of the response entity
