Xamarin.Forms 1.3.2

Important Note For Upgrading

This release updates several of the nuget packages referenced by Xamarin.Forms to support the latest GooglePlayServices. To ensure your projects are compatible, make sure your AndroidSDK is fully up to date (API 21 must be installed, as well as latest build tools), GooglePlayServices is up to date in the SDK manager, and that the Compile and TargetFramework of your android application is set to either Latest or 21 (if you use VS, 21 is probably better as you wont get nuget package errors, but both will work once the packages are installed).

So to wrap up, the following things are required:

  • Latest Android SDK installed. (Might take several runs of SDK Manager to get fully up to date)
  • Latest verison of GooglePlayServices installed
  • Android App Project set to TargetFramework 21, Minimum 15, Compile 21.
  • Nuget packages updated (should happen automatically when updating Forms)

Enhancements

  • Add implicit Xaml conversion for System.DateTime
  • Nuget package deps updated to latest version. This update is mandatory to maintain compatibility with GooglePlayServices 22.
  • Android now uses the correctly styled AlertDialog to display an ActionSheet
  • Minor performance improvements
