用户在同一Android设备上注销时如何生成新的令牌FCM？

Question

我试图发出触发令牌的通知。我还创建了onNewToken，但它始终仅在我的应用程序首次安装时生成。因此，如果用户注销我的设备并使用另一个帐户登录，它将不会生成新令牌。

我已经知道文档中的这种引用

• 该应用程序删除实例ID
• 该应用已在新设备上还原
• 用户卸载/重新安装应用程序
• 用户清除应用数据。

我的成就是，当用户在同一设备上注销时，它将在另一个用户登录时生成新令牌。

这是我的服务代码   公共类myFirebaseInstanceTokenID扩展了FirebaseMessagingService {

    private static final String TAG = "FirebaseMessagingServce";
    private static final String TAG2 = "MyFirebaseIIDService";


    FirebaseAuth mAuth = FirebaseAuth.getInstance();
    FirebaseUser user = mAuth.getCurrentUser();


    @Override
    public void onNewToken(String token) {
        Log.d(TAG2, "Refreshed token: " + token);

        if(user != null){
            Log.d(TAG2, "user ada: " + token);
        }else{
            Log.d(TAG2, "user tidak ada: " + token);
            SharedPreferences.Editor editor = getSharedPreferences("token_shared", MODE_PRIVATE).edit();
            editor.putString("token", token);
            editor.apply();
        }

    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {


        if (remoteMessage.getData().size() > 0) {
            Log.e(TAG, "Message data payload: " + remoteMessage.getData());
            Map<String, String> data = remoteMessage.getData();

            String data_type = data.get("data_type");
            Log.e(TAG, "data_type: " + data_type);

            if(data_type.equals("pengumuman")){
                String body_notif_pengumuman = data.get("body");
                String title_notif_pengumuman = data.get("title");
                sendNotificationPengumuman(body_notif_pengumuman, title_notif_pengumuman);
                Log.e(TAG, "body pengumuman: " + body_notif_pengumuman);
                Log.e(TAG, "title pengumuman: " + title_notif_pengumuman);
            }else if(data_type.equals("tugas")){
                Log.e(TAG, "masuk tugas: ");
                String body_notif = data.get("body");
                String title_notif = data.get("title");

                Log.e(TAG, "title: " + title_notif);
            }else if(data_type.equals("nilai")){
                Log.e(TAG, "masuk nilai");
                String judul_nilai = data.get("judul");
                String title_nilai = data.get("title");
                if(user != null) {
