How to use v6 with updated msal authentication library for Android

The Microsoft Graph sample Android app
https://github.com/microsoftgraph/msgraph-sample-android
no longer compiles with msgraph-sdk-java version 6.

There is an updated msal authentication library for Android
https://github.com/AzureAD/microsoft-authentication-library-for-android
and that works: I can sign in and out in a single account client application. But I have no idea how to connect to this library Microsoft Graph SDK for Java

Particularly: the old project had a class AuthorizationHelper that bridged for getting updated tokens between the signed in ClientApplication and the GraphServiceClient.

Any example or documentation on how build that connection with this v6 library?

先比較 msgraph-sample-android 專案與更新後的 Microsoft Authentication Library for Android 以及 msgraph-sdk-java v6 整合。閱讀 issue 中對舊版 AuthorizationHelper 的參考，並確認已登入的用戶端應用程式如何連線至 GraphServiceClient。當範例具有清楚的指引或可編譯的範例，並支援登入、權杖使用和登出時，即表示完成。
