Question

Facebook SDKを統合した後、近くのイベントを表示する方法は、AndroidのFacebookログインを意味しますか？ FacebookのSDKとの統合のコールバックメソッドのonsuccessに

AccessToken tok; 
tok = AccessToken.getCurrentAccessToken(); 
// login_button.setReadPermissions(Arrays.asList("user_location", "user_birthday", "user_likes", "user_events", "read_stream")); 

String id = tok.getUserId(); 
// String id=getResources().getString(R.string.facebook_app_id); 
Log.d("--id", id); 

new GraphRequest(
    AccessToken.getCurrentAccessToken(), "/"+id+"/events", null, HttpMethod.GET, 
    new GraphRequest.Callback() { 
     public void onCompleted(GraphResponse response) { 

      /* handle the result */ 
      Log.e("--result", response + ""); 

     } 
    } 
).executeAsync();

は、私はこのコードを書かれています。

しかし、それは見せている：

result: {Response: responseCode: 200, graphObject: {"data":[]}, error: null}
