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.

When building Xamarin Apps there is no easy out of the box mechanism to control your enviornmental settings such as web service url as your app migrates through the different environments such as Development, Staging and Production. With a little work we can add a configuration file very similar to how you would update a web.config or appsettings.json in an ASP.NET or ASP.NET Core application

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.

Let’s talk about using your Kindle Fire as a development device for Xamarin. It is running Android OS so you should be able to develop and test your apps on it just like any other android device. I was able to get the Xamarin Live Player working on my Kindle Fire with a simple workaround since the regular pairing was not working.

The single biggest problem I have seen while developing any type of mobile app is how do we handle offline sync? On most projects I have worked on this has been punted as a problem that isn’t worth the devs time until we are close to release. While this is a bad idea in my opinion, the team does not need to freak out about handling offline sync. It is easier than we make it for ourselves, today’s take away is “Don’t freak out, mobile sync is easy”
