Opt-out of Dark Mode on iOS, Android, UWP, and macOS

Everyone can't stop talking about dark mode now that iOS 13 and Android 10 are officially released. To my surprise I have actually really been enjoying dark mode on my desktop and mobile devices. I really want to go through all my apps and add proper dark mode support, however I just haven't had the time. When running apps on iOS 13 or macOS and flipping on dark mode can make your app look.... not so great: This can depend on the framework you are using, hard coded values, or a bunch of other…

Add ASP.NET Core's Dependency Injection into Xamarin Apps with HostBuilder

Dependency injection(DI) and inversion of control (IoC), have been a recurring theme in questions that I have received over the last six years. Sometimes it is around using constructor injection(), simple service containers, and often around full frameworks such as Prism or MVVM Light. I will be honest with you, I have never been a fan of DI/IoC when building mobile apps. My main reason is that there has never been any official pattern or recommendations from Google or Apple (or Microsoft/Xamari…

Control Text Size on Android Bottom Navigation View

It seems as though my obsession with the Android Bottom Navigation View aka Bottom Tabs will never end! This time I got a question about controlling the size of the text when the user taps on a tab. The default behavior is to zoom in on the text: Inside of your Android project's Resources/values folder create a new file called dimens.xml if it doesn't exist. Then add the following XML to override the size of the text when it is active and not active: James Montemagno

Xamarin.Forms: Fully Customize Bottom Tabs on Android & Turn Off Shifting

It seems as if the BottomNavigationView aka Bottom Tabs on Android is one of the top things that I write about on my blogs. There was an introduction post [https://blog.xamarin.com/exploring-androids-bottom-navigation-view/], how to use reflection to remove shifting on native Xamarin.Android [https://montemagno.com/remove-shifting-bottomnavigationview-android/], official support in Xamarin.Forms [https://montemagno.com/xamarin-forms-official-bottom-navigation-bottom-tabs-on-android/] , and most…

Xamarin.Forms: Drop Shadow/Elevation on Android Bottom Navigation TabbedPage

It is a tale as old of time fighting with Android elevation and drop shadows. First it was the Toolbar [https://montemagno.com/xamarin-forms-drop-shadows-on-navigation-toolbar/] on a Navigation page and now it is the new fancy bottom tabs [https://montemagno.com/xamarin-forms-official-bottom-navigation-bottom-tabs-on-android/] that we got in Xamarin.Forms 3.1. I know what you are thinking... another custom renderer... NOPE! You just have to know to set a few different properties correctly. H…

Enhanced Mobile App Versioning in Azure DevOps (VSTS) with Mobile Tasks

A little over a year ago, I introduced my Mobile App Tasks Extensions for iOS and Android [https://montemagno.com/introducing-vsts-mobile-build-tasks-extension/] into the Azure DevOps (VSTS) marketplace. For iOS and Android developers it made the tasks of versioning and adjusting package names a breeze. They were written completely in TypeScript with VS Code [https://montemagno.com/building-vsts-tasks-with-typescript-and-vs-code/] and of course are open source on GitHub [https://github.com/james…

Unique Device & App Installation Identifiers for Mobile Apps

One common query I get all the time from developers is how to get a unique device or application identifier [https://github.com/xamarin/Essentials/issues/61] for their mobile app. After deciding to not include an API for this in Xamarin.Essentials we heard a lot of different use cases for it including: * Client/Server Communication * Login Validation * In-App Purchase Verification * Licensing Purposes The next obvious question that you may have is why didn't we include it in Xamarin.Essen…

Android Emulators On Hyper-V Are Pretty Awesome

I have been a mobile developer for 7 years now and since the day I started one of my largest complaints has been the Android emulator. From the very start we had just ARM emulators that were a complete joke to work with as they moved at a snail's pace. From there a bunch of companies attempted to fix the problem by using custom built solutions on top of Virtual Box or Hyper-V. Google has done a lot of work in the last few years to improve the Android emulators with Quick Boot, more customization…
