Logcat printing "interface name: null" during each DefaultHttpClient execution method call - android

I am contacting a web service multiple times to get a JSON String via HttpGet and DefaultHttpClient.
...
DefaultHttpClient defaultHttpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = (HttpResponse)defaultHttpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
...
I find that LogCat is printing interface name: null with tag System.out for each time HttpResponse httpResponse = (HttpResponse)defaultHttpClient.execute(httpGet); is executed.
Am i establishing this http connection properly with HttpGet? Is there a different way?
How can i create this connection and not get interface name: null LogCat messages from the System.out tag?


Are you using the DefaultHTTPClient Asynchronously? I had a similar error in the past (Android 2.x) and found once I made a singleton for the DefaultHTTPClient and put my web request inside an AsyncTask this error went away.


Use these;
HttpClient client = new DefaultHttpClient();

I am making a simple login check application

when i am trying to run my application through an android device i gets the error as
Error in http connection org.apache.http.conn.HttpHostConnectException: Connection to http://192.168.0.105 refused.
I am using same network for my computer and device.
in my mainactivity i have
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://"+ip+"//Zeditsho_app/login.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
and my ipconfig activity is
public class IpconfigActivity {
public static String ip="192.168.0.105";
}
could anyone help me to sort out this?

Android HTTP PUT request probably differs from Post, because it doesnt work?

Here is how I use POST and it works:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
inputStream = httpEntity.getContent();
And I didnt know how to use PUT, so I got this code and I changed every "Post" to "Put"
but I dont think it works:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPut httpPut = new HttpPut(url);
httpPut.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPut);
HttpEntity httpEntity = httpResponse.getEntity();
inputStream = httpEntity.getContent();
When I try updating a user's account using this implementation ot PUT I get errors from the server. - "No session. Unauthorized."
When I use Chrome's postman with the same parameters, I get no problem, so I think my PUT implementation doesnt work.

You need to use the same DefaultHttpClient to make all the calls, because your session information is stored in the instance object.
If you need to use different instances, you may be able to do that getting the cookies from the login request and add them in the next requests using getCookieStore/setCookieStore.

Android - Error in http connection java.net.UnknownHostException:

Im trying to connect mysql with android but it throw me an error.
Error in http connection java.net.UnknownHostException:
Below is my code:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.pherma.net84.net/admin/getAllPeopleBornAfter.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
But the URL s working fine. Please copy n paste the url.

I forget to put network permission in manifest. Working fine now.

Response is fires an Exception though the url and request codes are correct

In code to connection
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI(url));
HttpResponse response = client.execute(request);
when it comes to response execute it's just fires an exception
java.lang.nullPointerException
i checked every thing i.e
"url receiving and passing to request.setURI() method, the url is ok but it still crashes on response Line"

// send a request and get response (if needed)
InputStream responseStream = client.execute(post).getEntity().getContent();

here you can get an good example Executing a HTTP POST Request with HttpClient
