我在我的应用程序中使用Retrofit库,我想将超时设置为60秒.Retrofit有办法做到这一点吗？

我这样设置Retrofit:

RestAdapter restAdapter = new RestAdapter.Builder()
    .setServer(BuildConfig.BASE_URL)
    .setConverter(new GsonConverter(gson))
    .build();

如何设置超时？

我对android开发比较陌生.我正在开发一个Android应用程序,我正在向Web服务器发送请求并解析json对象.我经常java.net.SocketTimeoutException: Connection timed out在与服务器通信时遇到异常.有时它会毫无问题地完美运行.我知道这个问题在很多时候都被提出过.但我仍然没有得到任何满意的解决方案来解决这个问题.我正在下面发布我的logcat和app-server通信代码.

public JSONObject RequestWithHttpUrlConn(String _url, String param){

    HttpURLConnection con = null;
    URL url;
    String response = "";
    Scanner inStream = null;
    PrintWriter out = null;
    try {
        url = new URL(_url);
        con = (HttpURLConnection) url.openConnection();
        con.setDoOutput(true);
        con.setRequestMethod("POST");
        if(param != null){
            con.setFixedLengthStreamingMode(param.getBytes().length);
        }
        con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        out = new PrintWriter(con.getOutputStream());
        if(param != null){
            out.print(param);
        }
        out.flush();
        out.close();
        inStream = new Scanner(con.getInputStream());

        while(inStream.hasNextLine()){
            response+=(inStream.nextLine());
        }
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch …

我在运行Android 4.3的仿真器上使用Retrofit时遇到问题，并且设备在Android 4.4.2上运行，而相同的代码在运行Android 7.1.1的另一个仿真器上正常运行

每次尝试执行get请求时，都会收到一个超时异常。
