I created a simple project based on your scenario, to get the contact in Android.

In this project, I use ContactsContract.Contacts as the data contract that is used to interface with contact data. The code queries contacts at the Uri defined by ContactsContract.Contacts.ContentUri, returning the columns selected from ContactsContract.Contacts.InterfaceConsts. The Items property in ViewModel is set with the result of List<string> instance from ReadContacts() method.

For more detail, please check the code in sample project which can be downloaded from here. Hope this help.
