使用Facebook注册后第二次打开我的android应用时，如何从第二次获取更新的用户数据？

Question

I tried to get updated data from Graph API using accessToken but it always showing Logout button screen.

accessTokenTracker = new AccessTokenTracker() {
            @Override
            protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
                accessToken = newAccessToken;
            }
        };

@Override
protected void onDestroy() {
    super.onDestroy();
    if(isFromFb){
        accessTokenTracker.stopTracking();
    }
}
if(accessToken != null) {

            GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.d("TestLog user : " , object.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday,picture.type(large),friends");
            request.setParameters(parameters);
            request.executeAsync();
        }

Answer 2

Sorry I did a small mistake there final I got the answer. I need to get current accessToken first. But earlier I taken only when onCurrentAccessTokenChanged method.

accessToken = AccessToken.getCurrentAccessToken();
accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
            accessToken = newAccessToken;
        }
    };

@Override
protected void onDestroy() {
    super.onDestroy();
    if(isFromFb){
        accessTokenTracker.stopTracking();
    }
}

if(accessToken != null) {

            GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.d("TestLog user : " , object.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday,picture.type(large),friends");
            request.setParameters(parameters);
            request.executeAsync();
        }
