java - 适用于 Android 的 Microsoft Translate API 出现 UnknownHostException

Question

我已尝试使用以下代码来使用 Microsoft Translator API 库实现翻译应用程序，发现 here 。我有一个有效的互联网连接，并且已经生成了有效的客户端 ID 和密码，但每当我尝试运行代码时，我都会收到 java.net.UnknownHostException。

我的代码:

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
             StrictMode.setThreadPolicy(policy);
             Translate.setClientId("Screened for the question"); //Change this
               Translate.setClientSecret("I have screened the client secret to ask in SO"); //change

               final TextView  text = (TextView) findViewById(R.id.textView1);
               Button Trans1 = (Button)findViewById(R.id.trans);
               Trans1.setOnClickListener(new View.OnClickListener(){
               public void onClick(View view) {
                   String word = "Hello";
                   try {
                   translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN);
                      // text.setText(translatedText);
                   } catch (Exception e) {
                       e.printStackTrace();
                   }
               }
               });

我在使用这个 api 时也遇到了同样的问题，它在更改行后有效

translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN); 至

translatedText = Translate.execute(word, Language.GERMAN);
