異常RestAdapter處理器

-2

我有一個Android應用程序都崩潰了，因爲我不明白的錯誤...異常RestAdapter處理器

  String TEST_URL = "http://10.0.2.2:8080"; 
      PersonSvcApi personService = new RestAdapter.Builder() 
        .setEndpoint(TEST_URL).setLogLevel(LogLevel.FULL).build() 
        .create(PersonSvcApi.class); 

      Person person = new Person(); 

      String id = "234"; 
      person.setAge("21"); 
      person.setName("Test"); 
      person.setId(id); 
      boolean ok = personService.addPerson(person); 
      Collection<Person> people = personService.getPersonList();

出現在最後兩行的錯誤，好像我做錯了什麼與連接，但我沒有得到它。我有Web服務器工作，我已經嘗試過使用它，它使用一個簡單的Java代碼。當我與Android做，我得到這樣的：

[NetworkOnMainThreadException]的可能重複（http://stackoverflow.com/questions/5150637/networkonmainthreadexception） – njzk2 2014-10-27 14:53:45

當您看到「產生的原因：android.os.NetworkOnMainThreadException」，這意味着你正試圖使主（UI）線程的網絡電話。網絡調用可能需要很長或很長時間才能執行，因此您不希望讓用戶等待（凍結UI /讓應用程序不響應）。

我猜測你使用Retrofit進行的網絡調用是在onCreate中，或者是由某個事件監聽器觸發的。您將希望在一個單獨的線程（Thread，AsyncTask）上進行此調用。
