TrueTime 有时不给值

Question

我在我的应用程序中实现了 Truetime。它工作正常，但有时当我打开我的应用程序时，我没有得到价值。我已经设置了每天的奖励方法，但是如果发生了那将是一个大问题。

这是代码，我通过它获得时间：

class GoogleTime extends AsyncTask<Void,Void,Void> {
        @SuppressLint("CheckResult")
        @Override
        protected Void doInBackground(Void... voids) {

            try {
                TrueTime.build().initialize();

                TrueTimeRx.build()
                        .initializeRx("time.google.com")
                        .subscribeOn(Schedulers.io())
                        .subscribe(date -> {
                           java.util.Date da = TrueTimeRx.now();
                            Log.w("PPPPP", "TrueTime was initialized and we have a time: " + da);

                            String mm= String.valueOf(da);

                            String name   = mm.substring(0, mm.lastIndexOf("GMT+06:00"));
                            String yyy   = mm.substring(mm.length()-4);

                            String f = name+yyy;
                            String []strArray=f.split(" ");

                            Month = getMonthInIntFormat(strArray[1]);
                            String dd = strArray[2];
                            String yy = strArray[4];


                            String  Datw = dd +""+Month+""+yy;


                            TotalDate =Integer.parseInt(Datw);

                            Log.w("PPPPP", "TrueTime was initialized and we have a time: " + TotalDate);


                        }

                        , Throwable::printStackTrace);


            } catch (IOException e) {
                e.printStackTrace();
            }

            return null;
        }


    }

我已经在创建时执行了 class。我在 .subscribe(date -> { 上也遇到了错误。它的说法 Resultof Single.subscribe() 被忽略了。

使用 HttpGet、客户端和响应，我设法从响应日期 Header 获取服务器的当前时间。我可以随时调用它，并且会得到自信的响应（Google 几乎 100% 可用，我可以相信获得正确的日期和时间）

try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpResponse response = httpclient.execute(new HttpGet("https://google.com/"));
        StatusLine statusLine = response.getStatusLine();
        if(statusLine.getStatusCode() == HttpStatus.SC_OK){
            String dateStr = response.getFirstHeader("Date").getValue();
            //Here I do something with the Date String
            System.out.println(dateStr);

        } else{
            //Closes the connection.
            response.getEntity().getContent().close();
            throw new IOException(statusLine.getReasonPhrase());
        }
    }catch (ClientProtocolException e) {
        Log.d("Response", e.getMessage());
    }catch (IOException e) {
        Log.d("Response", e.getMessage());
    }
