Android, NetworkOnMainThreadException google 드라이브

Question

Android에서 NetworkOnMainThreadException 문제가 있습니다.

Google API를 사용하여 Java 응용 프로그램을 구축합니다.

developers.google.com/api-client-library/java/apis/drive/v2 

내가 구글 libs와 같은 자바 코드에서 작동하는이 내 코드

String code = data.getStringExtra("code"); 
     GoogleTokenResponse response; 
     try { 
      response = drive_flow.newTokenRequest(code).setRedirectUri(DRIVE_REDIRECT_URI).execute(); 
      GoogleCredential credential = new GoogleCredential.Builder() 
      .setTransport(httpTransport) 
      .setJsonFactory(jsonFactory) 
      .setClientSecrets(DRIVE_CLIENT_ID, DRIVE_CLIENT_SECRET) 
      .build() 
      .setFromTokenResponse(response); 
      //Create a new authorized API client 
      drive_service = new Drive.Builder(httpTransport, jsonFactory, credential).build(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } //catch (NetworkOnMainThreadException e){ 

     //} 

(내가 잡을 때 NetworkOnMainThreadException의 drive_service가 null이됩니다)입니다

AVD 플랫폼 2.3.3 매우에 내 응용 프로그램 실행 좋아,하지만 4.1.1 (genymotion에서) 작동하지 않는다. 내 나쁜 영어에 대한

AsyncTask 시도 비동기 작업 내부

try { 
     response = drive_flow.newTokenRequest(code).setRedirectUri(DRIVE_REDIRECT_URI).execute(); 
     GoogleCredential credential = new GoogleCredential.Builder() 
     .setTransport(httpTransport)

사용하여 한 OnCreate에서이 코드() 메소드

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
.detectAll() 
.penaltyLog() 
.build(); 
StrictMode.setThreadPolicy(policy); 

참조 또는 AsyncT 내에서 Http 호출 사용 청하다.
