Xamarin.Forms 4.0 brings new enhancements to the platform that has Xamarin Developers excited. My favorite new feature is Xamarin Shell which creates simple APIs for building powerful apps that include Tab Bars, Flyout Menus and more! The tooling builds an Application Shell and let's the developer focus on buidling their application.

Xamain.Forms contain many Animations API that is accessible in the shared code. Most animation sequences can be leveraged in the shared code reducing the need to implement any platform specific code to handle animations. Scaling animations can add a lot of context to your sequences that provide context to your animations.

Expandable Menus are an easy way to add different modes or context to a screen without taking up very little screen space. An expandable menu places a small icon or the screen as an overlay and when the user taps on it the menu expands to show many options. An easy way to include a complex set of modes without cluttering up the entire page. This is common when the user interacts with the page differently depending on the mode.

Xamarin.Forms provides a simple control for adding tabs to any application but the standard implementation has some limitations. With a little knowledge of how iOS and Android work you can start creating beautiful Tabs in your Xamarin.Forms applications that support custom colors and custom text.

When adding custom animations to your Xamarin Applications don't immediately jump to the custom renderers and platform specific code, it is not needed. Often overlooked the Xamarin.Forms Animation APIs can usually handle your mobile apps animation needs. The APIs are built right into the platform so you can be confident your code will work across the platforms your application is being built for.

Xamarin.Forms 3.2.0 released a new feature that is sure to be a favorite among many developers. The TitleView allows developers to quickly customize the Navigation Bar like they never had to before. You can easily add custom images, controls, content, etc. Before the TitleView it was a very long process of creating a custom renderer and platform specific implementations.

AppCenter Push Notifications is an exciting new technology for handling Push Notifications in any mobile app. I use AppCenter quite a bit with my Xamarin projects so using AppCenter was a natural choice.

This is Part 2 in a 3 part blog series discussing AppCenter Push Notifications

Recently I was working on a Xamarin.Forms app that required push notifications for both iOS and Android. I started implementing Azure Notification Hub and was recommended by my friend James Montemagno that App Center supports push notifications. James quickly produced an amazing blog post that documents push notification and your options in Xamarin.

In Xamarin.Forms or Xamarin Android your project might get to a point where you run into issues with the java build failing for what appears to be no reason. At first glance the OutOfMemoryException may make no sense at all, but toggling some simple settings will get you back up and running.
