Android 前台调用API并提取数据

我正在创建一个应用程序，将数据从服务器拉入应用程序的本地数据库。即使在设备屏幕被锁定的情况下，应用程序也应该提取数据。我们只针对安卓10。我发现最好的选择是使用前台服务。设备RAM和电池使用对我们来说不是问题

下面的类创建一个前台服务。我想知道我在类中的何处编写代码来调用API以从服务器获取最新数据

public class MyService extends Service {

    private static final int ID_SERVICE = 101;

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, flags, startId);
        return START_STICKY;
    }

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

    @Override
    public void onCreate() {
        super.onCreate();

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        String channelId = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? createNotificationChannel(notificationManager) : "";
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId);
        Notification notification = notificationBuilder.setOngoing(true)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("Foreground Service")
                .setContentText("Always running...")
                .build();

        startForeground(ID_SERVICE, notification);
    }

    @RequiresApi(Build.VERSION_CODES.O)
    private String createNotificationChannel(NotificationManager notificationManager){
        String channelId = "my_service_channelid";
        String channelName = "My Foreground Service";
        NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
        channel.setImportance(NotificationManager.IMPORTANCE_NONE);
        channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        notificationManager.createNotificationChannel(channel);
        return channelId;
    }

}

我想您可能需要

onStartCommand
