HarmonyOS getDefaultCellularDataSlotIdSync接口在平板上无法使用？

Question

import data from '@ohos.telephony.data';

let slotId: number = data.getDefaultCellularDataSlotIdSync();

设置deviceType包括tablet时，就会有如下编译告警：

The default system capabilities of devices default,tablet do not include system capability of 'getDefaultCellularDataSlotIdSync'. Configure the capabilities in syscap.json. It may cause your application crush in some devices. Attention: Such illegal interface call will lead to compilation error in the future version!

Answer 1

平板可能不支持SIM卡，因此tablet.json中不默认配置这个权限，编译告警是为了提示开发者要关注运行时校验，开发者可使用canIUse隔离。
