如果http调用失败或无法在android中访问，则终止或停止后台线程

我在下面做，但如果服务器不可访问或不可用，它不会在2-3秒后将控制权交还给线程。10-15秒后打印完成请求。你知道为什么吗

public JSONArray makeHttpRequest(String url) {

    // Making HTTP request
    try {

        HttpParams httpParameters = new BasicHttpParams();
        // Set the timeout in milliseconds until a connection is established.
        // The default value is zero, that means the timeout is not used. 
        int timeoutConnection = 2000;
        HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
        // Set the default socket timeout (SO_TIMEOUT) 
        // in milliseconds which is the timeout for waiting for data.
        int timeoutSocket = 2000;
        HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

        DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);           

        HttpPost httpPost = new HttpPost(url);
        HttpResponse httpResponse = httpClient.execute(httpPost);
                    Log.d("error_trace", "Done making request");
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();

    } catch (Exception e) {
        e.printStackTrace();
        errorFlag = true;
    }

这可能是由数据连接中的延迟引起的。看看通过无线连接和非无线连接是否有区别。不，基本上我关闭了无线和4G，然后看到控制在10秒以上后恢复到线程状态。
