  private mAtManager: abilityAccessCtrl.AtManager
  private mTokenId: number
  private mContext?: Context
  private mPermissions: ArrayList<Permissions> = new ArrayList()

  constructor() {
    this.mAtManager = abilityAccessCtrl.createAtManager()
    let bundleInfo = bundleManager.getBundleInfoForSelfSync(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION)
    this.mTokenId = bundleInfo.appInfo.accessTokenId
  }

  public static init(context: Context): PermissionUtil {
    PermissionUtil.sUtil.mContext = context
    return PermissionUtil.sUtil
  }

  public addPermissions(permission: Permissions): PermissionUtil {
    this.mPermissions.add(permissio
