[md]启动后台长时任务需要在module.json5文件中配置长时任务权限ohos.permission.KEEP_BACKGROUND_RUNNING、同时为需要使用长时任务的ability声明相应的后台模式类型。

> "module": {
> "abilities": [
> {
> "backgroundModes": [
> "dataTransfer",
> "location"
> ], // 后台模式类型
> }
> ],
> "requestPermissions": [
> {
> "name": "ohos.permission.KEEP_BACKGROUND_RUNNING" // 长时任务权限
> }
> ]
> }

参考官网文档：

ServiceAbility组件配置：
