谷歌JSON解析問題

可能重複：
android.os.NetworkOnMainThreadException谷歌JSON解析問題

我決定使用google api client。我從this example得到一個解析JSON的類，它在android 2.2上工作正常。然而，當我在android 3.x或4.x上測試它崩潰。如何解決它？

public class GooglePlaces { 

    /** Global instance of the HTTP transport. */ 
    private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport(); 

    // Google API Key 
    private static final String API_KEY = "AIzaSyCRLa4LQZWNQBcjCYcIVYA45i9i8zfClqc"; 
    private static final String PLACES_SEARCH_URL = "https://maps.googleapis.com/maps/api/place/search/json?"; 
    private static final String PLACES_SEARCH_GEOPOINT_URL = "http://maps.googleapis.com/maps/api/geocode/json?"; 
    private static final String PLACES_TEXT_SEARCH_URL = "https://maps.googleapis.com/maps/api/place/search/json?"; 
    private static final String PLACES_DETAILS_URL = "https://maps.googleapis.com/maps/api/place/details/json?"; 
    private static final String DIRECTION_URL = "https://maps.googleapis.com/maps/api/directions/json?"; 
    private double _latitude; 
    private double _longitude; 
    private double _radius; 
    public String test = new String(""); 

    public PlacesList search(double latitude, double longitude, double radius, String types) throws Exception { 

     this._latitude = latitude; 
     this._longitude = longitude; 
     this._radius = radius; 

     try { 

      HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT); 
      HttpRequest request = httpRequestFactory.buildGetRequest(new GenericUrl(PLACES_SEARCH_URL)); 
      request.getUrl().put("key", API_KEY); 
      request.getUrl().put("location", _latitude + "," + _longitude); 
      request.getUrl().put("radius", _radius); // in meters 
      request.getUrl().put("sensor", "false"); 
      if (types != null) 
       request.getUrl().put("types", types); 

      PlacesList list = request.execute().parseAs(PlacesList.class); 
      // Check log cat for places response status 
      Log.d("Places Status", "" + list.status); 
      return list; 

     } catch (HttpResponseException e) { 
      Log.e("Error:", e.getMessage()); 
      return null; 
     } 
    } 


    public static HttpRequestFactory createRequestFactory(final HttpTransport transport) { 
     return transport.createRequestFactory(new HttpRequestInitializer() { 
      public void initialize(HttpRequest request) { 
       GoogleHeaders headers = new GoogleHeaders(); 
       headers.setApplicationName("AndroidHive-Places-Test"); 
       request.setHeaders(headers); 
       JsonObjectParser parser = new JsonObjectParser(new JacksonFactory()); 
       request.setParser(parser); 
      } 
     }); 
    } 
}

這是庫我的輸入：

google-api-client-1.10.3-beta.jar 
google-api-client-android2-1.10.3-beta.jar 
google-http-client-1.10.3-beta.jar 
google-http-client-android2-1.10.3-beta.jar 
google-oauth-client-1.10.1-beta.jar 
gson-2.1.jar 
guava-11.0.1.jar 
jackson-core-asl-1.9.4.jar 
jsr305-1.3.9.jar 
protobuf-java-2.2.0.jar

這是logcat的

使用GSON它比任何其他json庫好多了！ – binnyb

這不是一個JSON/GSON問題。這個問題，你是在UI線程上進行網絡調用。這是早期版本的Android中的一個警告 - 並且在更高版本的SDK中更改爲編譯錯誤（我認爲是3.0）。

底線，移動您的網絡調用關閉UI線程（使用AsyncTask）來解決這個問題。
