单声道为Android - Android.OS和Android.Provider程序集？

Question

我正在使用mono for android 4.6，试图获取设备信息。我见过的样品在下面，但我不确定要添加什么参考才能获得这些样品？

var device = Android.OS.Build.Device; //type or namespace OS does not exist...(missing  assembly?) 
var id = Android.Provider.Settings.Secure.GetString(ContentResolver, Android.Provider.Settings.Secure.AndroidId); //type or namespace 'Provider' does not exist..(missing assembly?) 

Answer 1

http://androidapi.xamarin.com/?link=P%3aAndroid.OS.Build.Device

它在Mono.Android.dll

Answer 2

定义试试这个方法：

using Android.OS; 
using Android.Provider; 
using Android.Content; 
using Android.App; 

var device = Build.Device; 
var id = Settings.Secure.GetString(Application.Context.ContentResolver, Settings.Secure.AndroidId);
