In this webinar, Xamarin Developer Evangelist James Montemagno provides a complete overview of the exciting new features and changes in Android Marshmallow. He also discusses the latest enhancements in Google Play Services and the Android Support Libraries. This webinar includes technical demos and a Q&A at the end.
In this webinar, Xamarin Developer Evangelist Mike James provides an overview of the top new and updated APIs in the latest iOS 9 release, including Multitasking, Search and more.
We’ve all heard about the various ways to build mobile apps such as web vs. hybrid vs. native…but what does that mean for .NET developers who enjoy the rich feature set of Visual Studio? Do we need to invest in (insert web framework of the month), expensive native platform developers or a shiny new Mac? In this session from TelerikNEXT, I covered your options as a .NET developer and showed several approaches to write apps that run on iOS, Android and Windows Phone. I looked at using Cordova (with Telerik AppBuilder), Windows Universal and Xamarin, as well as ASP.NET. This session offers you the information you need to make the best choice for you or your organization.
The post Building Mobile Apps with Visual Studio (Session Recording) appeared first on Telerik Developer Network.
via Creating a lightweight API wrapper with Refit | Jerrie Pelser.
With the explosion of web APIs it becomes much more common for applications to integrate in some fashion with external APIs. These APIs are typically RESTful APIs, and normally there will be an official wrapper available for a wide range of programming languages and platforms to allow other developers to more easily integrate with the API.
Sometimes however this may not be the case. It may be that the service in question simply do not see providing a .NET API wrapper as a priority, or that the official wrapper may be targeting the full .NET Framework, and you may be looking for something that you can use from WinRT, Xamarin or PCL libraries in general.
It may also be that you simply do not want to include a large external dependency in your application, or you may actually need an API wrapper for one of your own APIs.
In all of these cases you may be required (or tempted) to write you own wrappers. Writing API wrappers can however be a tedious process.
In these sort of situations I revert to using Refit, which is an open-source PCL library developed by Paul Betts, and it works across just about every flavour of the .NET framework – Xamarin, WinRT, Windows Phone 8, UPW, etc.
Learn how Xamarin and Azure App Services create native iOS, Android, and Windows mobile apps with a single toolset and codebase, enabling developers to innovate and get results faster than ever before. Together in this webinar we’ll help you solve the top challenges in creating mobile apps today, including:
* Secure authentication and single sign-on
* Data sync for immediate information access with backend data stores
* Connecting to Web APIs and existing services in the cloud and on-premises
* Coding for fast innovation and frequent releases
via Dotnet by Example: Using a full-size none-stretched background image in a Xamarin.Forms app.
I always like to use a kind of a translucent background image to my app’s screens, that makes it look a bit more professional than just a plain single-colored screen – a trick I learned from my fellow MVP Mark Monster in the very early days of Windows Phone development. Now that I am trying to learn some Xamarin development, I want to do the same thing – but it turns out that works a bit different from what I am used to.
via Blindsist – Assisting Visually Impaired People using IBM Bluemix Visual Recognition | Abdul Muhaymin – Being Student!.
This blog post will cover how I developed Blindsist app for Xhacknight.
The app was developed using Xamarin.Forms, targeting 3 major platforms (iOS, Android and Windows Phone) same time.
Blindsist is a simple one page application. Objective of the application is taking a photo using Smartphone, The photo is then uploaded to IBM Bluemix using REST Api. IBM Bluemix returns the data in Json format, which will be parsed and spoken out using Native Text to Speech services.
