Android连接超时异常

下面是代码，我得到例外（超时），请提供任何解决方案或教程相同。在4.0.4 api级设备上使用

 HttpClient client = new DefaultHttpClient();

HttpPost request = new HttpPost(url);

 List<NameValuePair> params = new LinkedList<NameValuePair>();

> param has some values and a string of bitmap.

 HttpResponse response = client.execute(request);

StringBuilder receivedData = new StringBuilder();

BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

String line = null;

while ((line = reader.readLine()) != null) 
{

receivedData.append(line);

}

HttpClient=newdefaulthttpclient（）；
HttpPost请求=新的HttpPost（url）；
List params=new LinkedList（）；
>param有一些值和一个位图字符串。
HttpResponse response=client.execute（请求）；
StringBuilder receivedData=新建StringBuilder（）；
BufferedReader=new BufferedReader（new InputStreamReader（response.getEntity（）.getContent（））；
字符串行=null；
而（（line=reader.readLine（））！=null）
{
receivedData.append（行）；
}

试试这个：

HttpConnectionParams.setConnectionTimeout(httpParams,
        TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);

首先，您需要了解什么是connectiontimeoutexception：

连接到HTTP服务器或等待来自HttpConnectionManager的可用连接时超时

因此，这意味着您的设备的internet无法与HTTP服务器建立连接，并且请求超时。您可以做以下两件事来避免这种情况：

在使用以下方法进行HTTP调用之前，请检查是否存在活动的internet连接：

public static Boolean checkActiveInternet(Context activity) {
ConnectivityManager cm = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = cm.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnectedOrConnecting()) {
        return true;
    } else if (netInfo != null&& (netInfo.getState() == NetworkInfo.State.DISCONNECTED|| netInfo.getState() == NetworkInfo.State.DISCONNECTING|| netInfo.getState() == NetworkInfo.State.SUSPENDED || netInfo.getState() == NetworkInfo.State.UNKNOWN)) {
        return false;
    } else {
        return false;
    }

}

按如下方式为HTTP请求设置更大的超时：

公共静态字符串连接（字符串url）引发IOException{

HttpGet httpget = new HttpGet(url);
HttpResponse response;
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 60 * 1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
int timeoutSocket = 60 * 1000;

HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
try {

    response = httpclient.execute(httpget);

    HttpEntity entity = response.getEntity();
    if (entity != null) {
        InputStream instream = entity.getContent();
        result = convertStreamToString(instream);
        // instream.close();
    }
} catch (ClientProtocolException e) {
    Utilities.showDLog("connect", "ClientProtocolException:-" + e);
} catch (IOException e) {
    Utilities.showDLog("connect", "IOException:-" + e);
}
return result;

}

使用AsyncTask并在中执行所有流程background@zalajanaksinh：这对我不起作用，先生……开始用谷歌搜索bgprocee的例子吧，它用的也是wotk亲爱的。
