[android-developers] Re: HttpClient GC_Concurrent freed

Have you tried analyzing your app with tools like ddms?

Hello.

Iam having trouble with memory leak it will finaly cause the app to force close.

I have stripped down my code just to find where the problem is and i located it to my httpclient.

When i run this code iam geting many GC_Concurrent freed.

if i add a Thread.sleep(1000); then i will ofcourse get less warnings but my guess is that there is still some problem with the code i run.

Is there a way i could prevent the problem.

Here is the code:

Thread c = new Thread() {

       @Override

public void run() {

                                String xml;

        UsernamePasswordCredentials creds = new UsernamePasswordCredentials("username", "password");

        HttpGet httpGet;

        HttpClient httpClient;

        HttpResponse httpResponse;

        HttpEntity httpEntity;

        while (RunThread) {

        try {

        httpClient = HttpClientFactory.getThreadSafeClient();

        httpGet = new HttpGet("http://ipaddress/list?format=xml");

        httpGet.addHeader(new BasicScheme().authenticate(creds, httpGet));

        httpResponse = httpClient.execute(httpGet);

        httpEntity = httpResponse.getEntity();

        xml = EntityUtils.toString(httpEntity, "UTF-8");

       

       

        } catch (Exception e) {

        e.printStackTrace();

       

        } 

            }

   };

   c.start();

   }

And here is the class HttpClientFactory

public class HttpClientFactory {

    private static DefaultHttpClient client;

    public synchronized static DefaultHttpClient getThreadSafeClient() {

  

        if (client != null)

            return client;

         

        client = new DefaultHttpClient();

        

        ClientConnectionManager mgr = client.getConnectionManager();

        

        HttpParams params = client.getParams();

        params.setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);

params.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);

        client = new DefaultHttpClient(

        new ThreadSafeClientConnManager(params,

            mgr.getSchemeRegistry()), params);

  

        return client;

    } 

}

Have a made some huge mistage in the code that is causing this issue?
