How to know the current OS / platform of the executing code (Android / iOS)

Question

Using Xamarin.Android and Xamarin.iOS, I need to now the current OS in a shared code section. Be it an enum, an int or a string, it doesn't matter.

I tried this:

System.Environment.OSVersion 

Which is always "Unix" with some kernel version informations.

There are info on Android for example like

Android.OS.Build.VERSION 

But it needs to be in the Android specific code section. Is there any way of knowing the current OS in a common library?

Answer 1

You can also try this and its probably the best solution I found :

if(Device.RuntimePlatform == Device.iOS) {     //iOS stuff } else if(Device.RuntimePlatform == Device.Android) {  } 

Answer 2

I'm using DeviceInfo plugin. It supports Android, iOs, Windows Phone Silverlight, Windows Phone RT, Windows Store RT, Windows 10 UWP and it works perfectly.

It can be used in PCL like this (you must add the plugin to the platform projects and to PCL):

var platform = CrossDeviceInfo.Current.Platform;     switch(platform){         case Platform.iOS:             // iOS             break;         case Platform.Android:             // Android             break;      } 

This kind of code isn't a good practice in PCL, its better to use Dependency Injection (this plugin use that) to customize platform specific behaviour.
