Microsoft has open sourced JUniversal, a tool for writing cross-platform mobile applications in Java.
amarin last week announced version 8.6 of its iOS SDK (Xamarin.iOS), the first non-beta release to include the company's Unified API for iOS and Mac. The Unified API replaces the 32-bit MonoTouch and MonoMac APIs, enabling code re-use across both platforms and adding 64-bit support.
HipByte released RubyMotion 3, which for the first time supports Android and Apple's WatchKit. A new pricing model attempts to better satisfy the developers needs.
Xamarin is encouraging developers to begin adding 64-bit support to their iOS apps. The request comes only two months before Apple’s February deadline for new app submissions to be built against the iOS 8 SDK with support for the 64-bit architecture.
Garrick Toubassi, Google Inbox engineering director, has recently explained how his team could get to "sharing roughly two-thirds of their client code" across three platforms: iOS, Android, and the web. The key is a clear separation of concerns between UI code and UI-independent logic, and a couple of tools that Google developed through the years.
research2guidance has published a study (PDF) comparing the top 40 cross-platform (CP) tools by asking 2,188 developers from 5 continents to name and rate their satisfaction with the tools they are using.
Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects.
Motorola RhoMobile 5.0 comes with a new licensing model, support for the latest iOS and Android versions, a set of new or improved cloud services – Build, Synchronization, Push Notification –, Zebra Printing support, and others.
F# has supported both iOS and Android native programming through Xamarin since at least Xamarin 4.8 and can be efficiently used to create native apps on both platforms. Let's give a look at some experience reports.
Google has published a number of guidelines and boilerplate code for cross-platform responsive website design.
Cordova/PhoneGap 3.5.0 no longer support iOS 5, 3.6.0+ will not support WP 7, and future updates will come through npm.
Up until now one could write with Xamarin cross-platform native mobile applications that shared 80% of the code on average with the rest of 20% representing UI code that had to be written separately for each platform. The latest release, Xamarin 3.0, introduces Xamarin.Forms, a MVVM library for writing a single UI code in C# being executed natively on iOS, Android or Windows Phone.
Dropbox developers have recently given some talks describing how they support both iOS and Android in their apps without having to recode everything on each platform. Let's review the reasons that led to their approach, the benefits it brings, and some key points learned through the process.
