We are planning on using the master-detail view for the Android version of the app while following the material design guidelines. For iOS the app will use a tabbed bar along the bottom of the screen and a settings icon in the navigation bar.
I had made this decision after I had put together a proof-of-concept app using the master-detail view, slapped a nice coat of material design paint on it and paraded it around to a few people for some feedback. It looked really nice, shiny…at least in Android, but not to worry, I could make some OS specific adjustments for iOS. It seemed like a good direction.
Yesterday, I took my proof-of-concept app, picked out the pieces I needed and rolled them into my actual app. The Android app was to have a navigation drawer (master) which slid over the tab page (detail). I spent the morning pulling everything together, applying the theme, adjusting colours, testing, then finally, I implemented the tabs in the detail page. This is what the result looked like:
Where I expected the master navigation drawer to slide over the toolbar and tabs, it instead only slid over the detail page. This is particularly problematic since not all of the detail pages use tabs.
I found numerous posts of this behaviour and a Xamarin bug report. Apparently it’s expected behaviour and will not be fixed.
I guess it’s back to the drawing board for the navigation…sigh.
We had the sprint retro for our first 2 week iteration and did not have much to show for it. The learning curve of Xamarin, plus time for planning and time stolen by other projects caused the velocity to make a major hit. Only 4 of 8 story points were completed in sprint 1, the remaining 4 story points were pushed into sprint 2. Nevertheless, we did have something to show for it, a working app, themed to meet the client’s needs with login and data retrieval functionality which was integrate with the real life backend.
There is quite a bit of learning left to do. We are working to find a good navigational flow for the app while ensuring it is visibly pleasing and meets the UI guidelines of both iOS and Android.

A couple of notes here. I am constantly working between a “test project” and a real project. The test project gives me the opportunity to experiment with various UI changes such as styles, controls, flows without impacting/polluting the real project, a way to make mistakes with little cost. Second, I have ran into this build issue with the default Xamarin.iOS project multiple times and thought it would be a good idea to share it.
Over the past 4 days, I have been working with Xamarin here and there. I’m starting to get the lay of the land, and I may actually have some things of value to share. Here’s a quick braindump:
When creating your Visual Studio solution/projects, start with “Blank App (Xamarin.Forms.Shared)”, this will create your “core” project containing all your common code, it will also create a project for iOS, Android and Windows Phone 8.1
If you have chosen to use a Hackintosh, like me, you will not be able to run the Windows Phone 8.1 emulator as it requires Hyper-V and Hyper-V does not play nicely with VirtualBox
When you create your Xamarin.Forms projects, you will need to manually edit the iOS project file as described here: https://kb.xamarin.com/customer/portal/articles/2006832-why-does-my-ios-build-fail-with-%22no-valid-iphone-code-signing-keys-found-in-keychain%22-
ALWAYS ensure your Mac build machine is running and ready BEFORE opening Visual Studio
Visual Studio Online supports Xamarin build, but it will not work with a trial license
That’s about it for now, just some quick tips from the trenches.
I’m a little late to the mobile game…like 9 years late, but I really haven’t been motivated to create anything for the mobile space. I have daydreamed about creating a fantastic mobile app for the iPhone and Android and it has remained just that, a daydream. When I put in after hours time, for hobby projects or training, it generally needs to be directly tied to my short to medium term career goals.
Now, I finally have an opportunity to create a mobile app at work.
This is exciting and I’m really looking forward to the journey!
I decided to start this blog as a structured brain-dump. Generally, I make notes in Onenote and it stays hidden from the universe, this time I want to try something different.
Here we are at ground 0, sprint 0, whatever you want to call it. I’m ramping up on Xamarin, starting with 3 Pluralsight courses:
I don’t have a Mac, and I don’t wish to have one or deal with one, so I’m going to be using Visual Studio Online (TFS 2015) and the built in Xamarin build capabilities to build my iOS app (see Brian Harry’s post).
