如何保存android通知并在重启时恢复它们

<receiver android:name=".NotificationReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

public class NotificationReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 获取之前保存的通知数据
        String notificationData = getSavedNotificationData();

        // 重新创建通知
        if (notificationData != null) {
            NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "channel_id")
                    .setSmallIcon(R.drawable.notification_icon)
                    .setContentTitle("Notification Title")
                    .setContentText("Notification Text")
                    .setPriority(NotificationCompat.PRIORITY_DEFAULT);

            // 设置通知的其他属性

            Notification notification = builder.build();
            notificationManager.notify(notificationId, notification);
        }
    }

    private String getSavedNotificationData() {
        // 从持久化存储中获取保存的通知数据
        // 返回通知数据的字符串形式
    }
}

private void saveNotificationData(String notificationData) {
    SharedPreferences sharedPreferences = getSharedPreferences("notification_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();

    editor.apply();
}

private void showNotification() {
    // 创建通知
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
            .setSmallIcon(R.drawable.notification_icon)
            .setContentTitle("Notification Title")
            .setContentText("Notification Text")

    String notificationData = convertNotificationDataToString(notification);
