Yandex API Translator不能在Android應用程序上工作

Question

我想在我的Android應用程序中使用Yandex翻譯器，但它給出錯誤。在Java應用程序（主要）中測試時，它可以很好地工作。我的問題是什麼？

主要代碼：

import com.rmtheis.yandtran.language.Language; 
import com.rmtheis.yandtran.translate.Translate; 
import com.veryinteligent.jarvas.R; 

import com.veryinteligent.jarvas.activity.WordCommands; 

import android.app.Activity; 
import android.os.Bundle; 

public class YandexTranslator extends Activity{ 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.wordcommands); 
     Translate.setKey(WordCommands.myKey); 
     String term = "obrigado por me ajudar"; 
     try { 
      term = Translate.execute(term, Language.PORTUGUESE, Language.ENGLISH); 
     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     System.out.println(term); 
    } 
} 

import com.rmtheis.yandtran.language.Language; 
import com.rmtheis.yandtran.translate.Translate; 

public class TranslationTester { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     Translate.setKey("trnsl.1.1.20160515T173032Z.cb8002677c95725e.93f4f996a1647d5d0c6e336758723a8bb1bb41b4"); 

     String term = "abrir vá"; 
     try { 
      term = Translate.execute(term, Language.PORTUGUESE, Language.ENGLISH); 
     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     System.out.println(term); 

    } 

} 

錯誤：

Answer 1

我使用此代碼here，它爲我

1正常工作：添加json_simple-1.1.jar到您的項目Tutorial

2：從複製班級代碼到項目

3：將在ApiKeys.java

4 API密鑰：把這個行文本翻譯：

Translate.setKey(ApiKeys.YANDEX_API_KEY); 

    String translatedText = Translate.execute("Hola, mundo!", Language.SPANISH, Language.ENGLISH); 

5：如果你android.os.NetworkOnMainThreadException錯誤是因爲這將引發異常當應用程序試圖執行它的主線程聯網操作，解決方案：

- 添加此行您YandexTranslatorApi.java

static class RetrieveResponse extends AsyncTask<URL,Void,String>{ 

     @Override 
     protected String doInBackground(URL... params) { 
      String result = ""; 
      try { 
       result = retrieveResponse(params[0]); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
      return result; 
     } 
    } 

- 在retrievePropString和retrievePropArrString方法改變這一行：

final String response = retrieveResponse(url); 

本：

final String response = new RetrieveResponse().execute(url).get(); 

編輯： 添加<uses-permission android:name="android.permission.INTERNET" />您AndroidManifest.xml 好運^ _^
