Android Invalid use of SingleClientConnManager: connection still allocated

问题

Please note this question is unique for my HTTP call.

I have look around and some ppl say httpResponse.getEntity().consumeContent();

but I can use it, because I need to provide a return data.

I call my API doInBackground.... as return api.post("analytics", params);

How can I fix the invalid SingleClientConnManager into this http post :

public String post(String url, List<NameValuePair> params) {
    HttpPost request = new HttpPost(BASEURL + url); 
    HttpResponse response;

    try {
        request.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
        response = client.execute(request);
        HttpEntity entity = response.getEntity();            

        return EntityUtils.toString(entity);
    } 
    catch(ClientProtocolException e) {            
        return e.toString();
    } 
    catch(IOException e) {           
        return e.toString();
    }       
}//end post

This is the error I am getting :

回答1:

After searching, I found this solution

HttpResponse httpResponse = httpClient.execute(httpPost);

//instead of httpClient use getThreadSafeClient() method.
HttpResponse httpResponse = getThreadSafeClient().execute(httpPost);

public static DefaultHttpClient getThreadSafeClient() {
        DefaultHttpClient client = new DefaultHttpClient();
        ClientConnectionManager mgr = client.getConnectionManager();
        HttpParams params = client.getParams();
    client = new DefaultHttpClient(new ThreadSafeClientConnManager(params,
                mgr.getSchemeRegistry()), params);
   
        return client;
    }
