权限被拒绝使用Xamarin.Mobile访问联系人列表xamarin.form

Question

嗨，美好的一天每个人我使用Xamarin.Mobile，但我的权限被拒绝错误我已经在AndroidManifest中添加了READ_CONTACTS，并且还在运行时添加权限。如何解决这个问题？

方法

public async Task<IEnumerable<MobileUserContact>> GetAllContacts() 
    { 
     if (_contacts != null) return _contacts; 

     var contacts = new List<MobileUserContact>(); 
     await _book.RequestPermission().ContinueWith(t => 
     { 
      if (!t.Result) 
      { 
       Log.Debug("PERM", "Permission Denied!"); 
       return; 
      } 
      foreach (var contact in _book.Where(c => c.Emails.Any())) // Filtering the Contact's that has E-Mail addresses 
      { 
       var firstOrDefault = contact.Emails.FirstOrDefault(); 
       if (firstOrDefault != null) 
       { 
        contacts.Add(new MobileUserContact() 
        { 
         ContactFirstName = contact.FirstName, 
         ContactLastName = contact.LastName, 
         ContactDisplayName = contact.DisplayName, 
         ContactEmailId = firstOrDefault.Address, 
         ContactNumber = contact.Phones.ToString() 
        }); 
       } 
      } 
     }); 

     _contacts = (from c in contacts orderby c.ContactFirstName select c).ToList(); 
     return _contacts; 
    }

貌似找你不能要求用户权限来访问他们的联系人。

看看这里：https://github.com/jamesmontemagno/PermissionsPlugin ，我会建议使用这一个了：https://github.com/jamesmontemagno/Xamarin.Plugins/tree/master/Contacts
