如何使用小型系统的service

华为文档里有，楼主可以参考下https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ability-service-creating-0000000000044464

public class ServiceAbility extends Ability {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
    }

    @Override
    public void onCommand(Intent intent, boolean restart, int startId) {
        super.onCommand(intent, restart, startId);
    }

    @Override
    public IRemoteObject onConnect(Intent intent) {
        return super.onConnect(intent);
    }

    @Override
    public void onDisconnect(Intent intent) {
        super.onDisconnect(intent);
    }

    @Override
    public void onStop() {
        super.onStop();
    }
}
