如何在android中每天定时自动更新firebase实时数据库？

public class MyService extends Service {
    private static final long INTERVAL = 24 * 60 * 60 * 1000; // 24小时

    private AlarmManager alarmManager;
    private PendingIntent pendingIntent;

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 创建定时任务
        alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Intent alarmIntent = new Intent(this, MyService.class);
        pendingIntent = PendingIntent.getService(this, 0, alarmIntent, 0);

        // 设置每天定时执行的时间间隔
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY, 0); // 设置小时
        calendar.set(Calendar.MINUTE, 0); // 设置分钟
        calendar.set(Calendar.SECOND, 0); // 设置秒钟

        // 设置定时任务
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), INTERVAL, pendingIntent);

        // 执行定时任务
        updateFirebaseDatabase();

        return START_STICKY;
    }

    private void updateFirebaseDatabase() {
        // 在这里执行更新Firebase实时数据库的操作
        // 例如，你可以使用Firebase Realtime Database的API来更新特定节点的数据
        // DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference();
        // databaseRef.child("your_node").setValue("your_value");
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

<service
    android:name=".MyService"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</service>
