HarmonyOS 申请APP\_TRACKING\_CONSENT权限无反应，麦克风权限能正常申请？

Question

public reqPermissionsFromUser(permissions: Array<Permissions>, context: common.UIAbilityContext): void {
  let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
  // requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
  atManager.requestPermissionsFromUser(context, permissions).then((data) => {
  let grantStatus: Array<number> = data.authResults;
  let length: number = grantStatus.length;
  for (let i = 0; i < length; i++) {
  if (grantStatus[i] === 0) {
  // 用户授权，可以继续访问目标操作
} else {
  // 用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限
  return;
}
}
// 授权成功
}).catch((err: BusinessError) => {
  console.error(`Failed to request permissions from user. Code is ${err.code}, message is ${err.message}`);
})
}


voicePermissions: Array<Permissions> = ['ohos.permission.MICROPHONE'];
oaidPermissions: Array<Permissions> = ['ohos.permission.APP_TRACKING_CONSENT'];

Answer 1

OAID权限在beta1版本之后被默认禁止（模拟器并没有这个限制），目前该权限暂时不开放了，是默认禁止状态。再申请授权后，如果需要用到该权限，可以引导用户打开此权限，只有在用户requestPermissionsFromUser这个接口之后，并且用户选择是否授予权限之后，才会在应用详情页显示该权限开关

参考demo

import WebView from '@ohos.web.webview';
import { abilityAccessCtrl, common, Permissions } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { identifier } from '@kit.AdsKit';
import { hilog } from '@kit.PerformanceAnalysisKit';

    // requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
    atManager.requestPermissionsFromUser(context, permissions).then((data) => {
      let grantStatus: Array<number> = data.authResults;
      let length: number = grantStatus.length;
      for (let i = 0; i < length; i++) {
