HarmonyOS应用开发-Page Ability启动Service Ability

Page Ablity响应交互，从而调用Service Ability是鸿蒙开发中最常用的交互方式，在Page Ablity使用startAbility(intent)启动Service Ability，Service Ability端在onCommend做出响应。
Page Ablity：

Operation operation = new Intent.OperationBuilder()
        .withDeviceId("")
        .withBundleName("mytest.app")
        .withAbilityName("com.example.album.Ability.service.PlayServiceAbility")
        .build();
intent.setOperation(operation);
intent.setParam("item",item);
// 启动Service
context.startAbility(intent,0);

Service Ability：

protected void onCommand(Intent intent, boolean restart, int startId) {
    super.onCommand(intent, restart, startId);
    HiLog.info(TAG, "发布公共事件");
    //这里写响应内容
  
}
