cl.ability.1 应用组件启动规则变更
元能力子系统应用组件启动规则在如下场景中存在变更:
- 应用位于后台启动应用组件
- 跨应用启动invisible应用组件
- 跨应用启动FA模型的serviceAbility与dataAbility
- 使用startAbilityByCall接口
开发者需要根据以下说明对应用进行适配。
变更影响
若未适配新规则,在上述场景下将无法启动应用组件
> 注意,启动应用组件是指一切启动或连接Ability的行为:
1. 启动Ability,如使用startAbility、startServiceExtensionAbility、startAbilityByCall等接口。
2. 连接Ability,如使用connectAbility、connectServiceExtensionAbility、acquireDataAbilityHelper、createDataShareHelper等接口。

适配指导
不同场景下的启动规则说明如下:
- 应用后台启动应用组件
- OpenHarmony 3.2-beta3 版本规则:
- 应用位于后台时,启动应用组件不受任何限制。
- OpenHarmony 3.2-beta4 版本新规则:
- 当应用位于后台时,启动应用组件需鉴权,需申请的权限如下:
- json
{
"name": "ohos.permission.START_ABILITIES_FROM_BACKGROUND",
"grantMode": "system_grant",
"availableLevel": "system_basic",
"provisionEnable": true,
"distributedSceneEnable": false
}
> 注:
1. 即使启动同应用的组件,也受该规则限制。
2. 对于API8以及之前的SDK,启动serviceAbility和dataAbility不受此规则限制。
跨应用启动invisible应用组件
- OpenHarmony 3.2-beta3 版本规则:
- 对于APL为normal的应用,无法跨应用启动invisible的应用组件
- OpenHarmony 3.2-beta4 版本新规则:
- 所有应用,若需要跨应用启动invisible的应用组件,需鉴权,需申请的权限如下:
json { "name": "ohos.permission.START_INVISIBLE_ABILITY", "grantMode": "system_grant", "availableLevel": "system_core", "provisionEnable": true, "distributedSceneEnable": false }
- OpenHarmony 3.2-beta3 版本规则:
跨应用启动FA模型的serviceAbility与dataAbility
- OpenHarmony 3.2-beta3 版本规则:
- 可任意跨应用启动serviceAbility与dataAbility
- OpenHarmony 3.2-beta4 版本新规则:
- serviceAbility与dataAbility的提供方应用需配置关联启动,否则无法被跨应用拉起。(普通应用无法配置关联启动)
- OpenHarmony 3.2-beta3 版本规则:
startAbilityByCall接口
OpenHarmony 3.2-beta3 版本规则:
- 可任意进行Call调用
OpenHarmony 3.2-beta4 版本新规则:
不支持同应用startAbilityByCall调用
跨应用startAbilityByCall调用需鉴权,需申请的权限如下:
-
{ "name": "ohos.permission.ABILITY_BACKGROUND_COMMUNICATION", "grantMode": "system_grant", "availableLevel": "system_basic", "provisionEnable": true, "distributedSceneEnable": false }
注:
使用startAbilityByCall接口同时也受上述后台启动、跨应用启动invisible规则的限制。
cl.ability.2 跨设备应用组件启动规则变更(仅支持系统应用)
元能力子系统跨设备应用组件启动规则在如下场景中存在变更:
- 应用位于后台启动应用组件
- 跨应用启动invisible应用组件
- 跨应用启动FA模型的serviceAbility
开发者需要根据以下说明对应用进行适配。
变更影响
若未适配新规则,在上述场景下将无法启动应用组件
> 注意,启动应用组件是指一切启动或连接Ability的行为:
1. 启动Ability,如使用startAbility、startAbilityForResult、startAbilityByCall等接口。
2. 连接Ability,如使用connectAbility等接口。

- 关联启动配置

- OpenHarmony 3.2-beta3 版本规则:
cl.ability.3 API异常处理方式变更
元能力部分接口使用业务逻辑返回值表示错误信息,不符合OpenHarmony接口错误码规范。
变更影响
基于此前版本开发的应用,需适配变更接口的错误信息返回方式,否则会影响原有业务逻辑。
关键接口/组件变更
为适配统一的API异常处理方式,对元能力相关接口进行废弃(下表中 原接口 列内容,其中的API9接口将被删除,API8及以前的接口将被标注为废弃),并新增对应接口(下表中 新接口 列内容)。新增接口支持统一的错误码异常处理规范,功能上与原接口保持一致。

适配指导
如上所述,仅将老接口平移到了新的namespace中,所以可以通过修改import来解决适配问题:
如原先接口使用了@ohos.application.missionManager
import missionManager from '@ohos.application.missionManager';
可以通过直接修改import,来切换到新的namespace上:
import missionManager from '@ohos.app.ability.missionManager';
此外还需要适配异常处理,具体参考新接口的接口文档。
