アンドロイドスタジオのGoogleマップで、1人のユーザーの現在地を他の場所に表示するにはどうすればよいですか？

Question

私はGoogleマップを使用してアプリを開発していますが、私は彼の管理者に現在のドライバを表示します。彼の管理者にドライバの現在地をどのように表示するのですか？どのように私はドライバの現在の場所を追跡し、彼の管理者に表示するのですか？

次のコードはドライバの現在の位置のみを表示しています。このドライバの現在の位置を管理者に表示するにはどうすればよいですか？

Answer 1

これが解決策の一つ
1.ユーザの現在位置を取得して、サーバー上でそれを更新している可能性があります。
2.バックエンドサーバーにFirebaseを使用します。これにより、多くの作業が簡単になります。ユーザーの場所をfirebaseに保存します。
3.管理パネルで、firebaseからユーザーの場所を取得します。
通知を使用して、ユーザーがfirebaseで更新したら、そのユーザーの現在の場所についてadminに通知できます。
