Sample Android Xamarin Forms project exhibiting crash on API level 15 on startup

Creating a simple Xamarin Forms project using a TabbedPage and then updating it with Material Design stylings (ref: https://blog.xamarin.com/material-design-for-your-xamarin-forms-android-apps/) causes a startup crash on a Galaxy Note 1 running Android 4.0.4. The issue does not occur targeting API level 16 or API level 22, but does for Galaxy Note 1 running API level 15 - repro project attached.

Exception details:

Comment 1 Roger Peters 2016-01-18 19:33:50 UTC
To clarify, I should not have used the word 'targetting' - I meant selecting different devices to run against. The project properties are set to their defaults, which is having API level 15 as the minimum Android version, and API level 23 as the target Android version. All I am doing is changing what it is deploying to - and it crashes when deploying to a level 15 device.
Comment 2 James Montemagno [MSFT] 2016-01-18 22:11:47 UTC
Confirmed here, current work around is to target API 16+ when using material tabs.
Comment 3 Rui Marinho 2016-01-20 11:41:57 UTC
Should be fixed in 2.1.0-pre1
Comment 4 Parmendra Kumar 2016-02-04 17:39:22 UTC
I have checked this issue with Xamarin.Forms 2.1.0.6508-pre3 and its working fine.

Hence closing this issue.
