Android: InstanceID deleteToken范围

Question

我在一个应用程序中实现了Google消息传递。首先，我使用InstanceID获取令牌，下一步是在我的服务器上注册设备，并得到一个HttpResponse。根据此响应，我希望删除令牌并在我的服务器中注销设备。这是代码：

// [START register_for_gcm]
            InstanceID instanceID = InstanceID.getInstance(this);
            final String token = instanceID.getToken(manager.getSenderID(),GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            // [END get_token]
            Log.i(TAG, "GCM Registration Token: " + token);
            final Context context = ApplicationContextProvider.getContext();
            mRegisterTask = new AsyncTask<Void, Void, Void>() {
                @Override
                protected Void doInBackground(Void... params) {
                    HttpResponse response = manager.registerDevice(context, App.getInstance().getAppId(), token, null, null);
                    // At this point all attempts to register with the app server failed, so we need to unregister the device from GCM - the app will try to register again when
                    // it is restarted. Note that GCM will send an unregistered callback upon completion, but GCMIntentService.onUnregistered() will ignore it.
                    if (String.valueOf(response.getStatusLine().getStatusCode()).equals(200)==false){
                        instanceID.deleteToken(token, scope);
                        manager.unregister(context);
                    }
                    return null;
                }

                @Override
                protected void onPostExecute(Void result) {
                    mRegisterTask = null;
                }
            };
            mRegisterTask.execute(null, null, null);

我正在寻找安卓开发者谷歌开发者InstanceID，然后我找到了deleteToken(String authorizedEntity, String scope)。authorizedEntity是在getToken()方法中获得的令牌，但我不知道作用域是什么。有人能帮我吗？

范围是"GCM“或常量。

GoogleCloudMessaging.INSTANCE_ID_SCOPE

authorizedEntity是您的项目编号。这是参考链接
