What Xamarin Developers Ought to Know to Start in 2017

Inspired by Scott Hanselman’s recent blog on what .NET Developers ought to know to start 2017 [http://www.hanselman.com/blog/WhatNETDevelopersOughtToKnowToStartIn2017.aspx] I thought I would take it a step further to create a small guide for Xamarin developers creating iOS, Android, and macOS apps in .NET. So I sat down with Chris Hardy [http://twitter.com/chrisntr] and put together a list of Xamarin specific terms and resources. Before we start, you should totally go read Scott’s awesome bl…

How to Build & Ship an App in a Week with Xamarin.Forms

TLDR; I built an app in a few days over the holidays to keep track of board game and sport scores called Scoreboard, which is available now on iOS [https://itunes.apple.com/us/app/scoreboard-game-score-keeper/id1191033523?ls=1&mt=8] and Android [https://play.google.com/store/apps/details?id=com.refractored.scoreboard]! Over the holidays I didn’t expect to sit down and write an entire app for iOS and Android from scratch, but I did. It all started when Heather and I were playing Qwirkle [ht…

Going Serverless with Azure Functions: SendGrid

A while back I wrote an app called MyShoppe [https://github.com/jamesmontemagno/MyShoppe], which served as a sample application that would enable any business owner with multiple locations to build an app to help their customers get store information and leave feedback. This was more than just a sample application as I built the original application for my brother who has several stores in Texas. The Old Backend The app isn’t overly complex. I leveraged Azure Mobile Apps (at the time Mobile Ser…

Xamarin.Forms: Google Admob Ads in iOS

Xamarin.Forms: Google AdMob Ads in Android

I have been recently experimenting with integrating ads into my applications as an experiment. Not really to make money, but to just get it setup and working. I recently experimented with both Facebook Ads and Google AdMob for my iOS app “Social Post” and the results have been pretty good. I discussed this strategy a few weeks back on the Merge Conflict [http://mergeconflict.fm] podcast with Frank on Monitization. Now, it is time to go a step further and add some ads into my Xamarin.Forms ap…

Setting Up Android x86 HAXM Emulators

I have recently had tons of questions about my recommended settings for Android x86 Emulators on Windows or on Mac. I have recently moved away from they Hyper-V Android Emulators for VS [https://www.visualstudio.com/vs/msft-android-emulator/] (which are awesome), just so I have all of the Google APIs around. So here we go. 1. Install the Intel x86 Emulators from Intel [https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager] 2. When installing make…

Xamarin.Forms: Java.Lang.IllegalStateException

Since this one keeps coming up time and time again I figured I would write a quick blog about it. The dreaded: Java.Lang.IllegalStateException: Can not perform this action after onSaveInstanceState. that keeps crashing your application. What is it, why is it happening, and how do you fix it. This actually can happen in non-Xamarin.Forms Android applications, but it seems to keep coming up in the Forums and in GitHub due to the heavy use of async/await, plugins, and developers attempting to nav…
