Description Mark McLemore 2016-10-14 22:17:28 UTC
Entered the following sample code in a Workbook (Windows 10):

  using Android.App;
  using Android.Widget;
  using Android.OS;

  var rootActivity = StartedActivities.First ();
  Switch mySwitch = new Switch (rootActivity);
  mySwitch.ShowText = true;

When I try to run it, I get the error: "(7,10): error CS1061: 'Switch' does not contain a definition for 'ShowText' and no extension method 'ShowText' accepting a first argument of type 'Switch' could be found.

However, Switch.ShowText is supported by Xamarin.Android:


Also, I can instantiate a Switch and access its ShowText property without error in Visual Studio.
Comment 1 Sandy Armstrong [MSFT] 2016-10-14 23:12:21 UTC
Although Xamarin docs claim that Switch.ShowText is available as early as API 14 (ICS, 4.0.3), Android's docs reveal the truth: it is not available until API 21 (Lollipop, 5.0).

Currently, the Xamarin Workbooks Android app is built using API 19 (KitKat, 4.4), and does not have access to newer APIs.

This decision was based on what device images were available for Xamarin Android Player, as well as what devices it seemed likely developers would already have installed.

Leaving this open as a feature request. Perhaps we could ship a version built against latest stable Android as well, and let the user get that if they have set up a device for it. Every app we add to Workbooks adds a big hit to install size though.
