Last year at the Build conference, Microsoft announced what was called Project Astoria, a bridge that will allow developers to port their existing Android apps easily to Windows 10. The feature eventually disappeared from Windows 10 builds that came out after that, which caused some people to wonder what was happening with the feature. Microsoft has now confirmed that it will no longer be working on that.
Microsoft stated that the company will instead focus only on the iOS Bridge that allows developers to port their iOS apps to Windows, instead of having one each for iOS and Android as "having two Bridge technologies to bring code from mobile operating systems to Windows was unnecessary, and the choice between them could be confusing."
Microsoft also recently acquired the company Xamarin that lets developers write their apps in one language and then customize it for different platforms. Microsoft thinks these two methods, along with the Web Bridge (for porting web apps) and Project Centennial (for porting existing Win32 and .NET apps) will be enough options for developers looking to port their apps to Windows 10 platforms.
