android - VKSdk.authorize() 后的 VKRequest 抛出错误 "invalid user id"。相继？

Question

我通过单击 Button 请求获取用户个人资料信息。我进行了调试，当我刚刚打开应用程序并单击按钮 onError 回调时，它显示“无效的用户 ID”。如果我第二次按 Button 它工作正常。从实验中我了解到应用程序没有完成授权，这就是请求被拒绝的原因。通过按下 Button 使用此代码调用方法:

VKSdk.authorize(VKScopes.EMAIL);
VKRequest request = VKApi.users().get(VKParameters.from(VKApiConst.FIELDS,
    "user_id,first_name,last_name,sex,bdate,city,photo_200_orig"));
request.secure = false;
request.useSystemLanguage = true;
request.executeWithListener(new VKRequest.VKRequestListener() {
     @Override
     public void onComplete(VKResponse response) {
         super.onComplete(response);
         //do some stuff
     }
     @Override
     public void attemptFailed(VKRequest request, int attemptNumber, int totalAttempts) {
          super.attemptFailed(request, attemptNumber, totalAttempts);
          Log.d("VkDemoApp", "attemptFailed " + request + " " + attemptNumber + " " + totalAttempts);
    }
    @Override
    public void onError(VKError error) {
         super.onError(error);
         Log.d("VkDemoApp", "onError: " + error);
    }
    @Override
    public void onProgress(VKRequest.VKProgressType progressType, long bytesLoaded, long bytesTotal) {
         super.onProgress(progressType, bytesLoaded, bytesTotal);
         Log.d("VkDemoApp", "onProgress " + progressType + " " + bytesLoaded + " " + bytesTotal);
    }
});

我尝试添加 if(VKSdk.wakeUpSession()) ，但它只是通过了，因为用户尚未获得授权。我在示例回调 onTokenExpired 中发现作为 listener 的一部分，如果需要我会在其中授权用户，但是当我添加它时说“从未使用过”。

我如何才能等到 VKSdk.authorize() 完成工作并仅在发送请求之后？提前致谢!

这是 onCreate() 中的行

VKSdk.initialize(sdkListener, activity.getResources().getString(R.string.vk_app_id));
VKUIHelper.onCreate(this);

VKSdkListener

VKSdkListener sdkListener = new VKSdkListener() {
    @Override
    public void onAcceptUserToken(VKAccessToken token) {
    }

    @Override
    public void onReceiveNewToken(VKAccessToken newToken) {
        //requesting the code at the top (request)
        //excluding the line VKSdk.authorize(VKScopes.EMAIL);
    }

    @Override
    public void onRenewAccessToken(VKAccessToken token) {
    }
    @Override
    public void onCaptchaError(VKError vkError) {
    }
    @Override
    public void onTokenExpired(VKAccessToken vkAccessToken) {
    }
    @Override
    public void onAccessDenied(VKError vkError) {
    }
};

在 onClick() 中有一行 VKSdk.authorize(VKScopes.EMAIL);

注意 VkSdkListener 的回调不是在initialize() 之后调用，而是在authorize() 之后调用。我不知道为什么，这种行为很糟糕。很高兴看到包含已获取用户的电子邮件和上面列出的其他内容的工作示例。

我可能是错的，但请尝试将“user_id”更改为“id”。第二个问题(授权后如何获取数据)的答案很简单。VKsdk 有一个带有抽象方法的监听器，您可以(并且应该)覆盖这些方法。
