The BlackBerry operating system is proprietary; releases beginning with BlackBerry 10 include support for applications written for the Android platform. As such, developers can use almost any programming language that can be used for other smartphones, including Java, Adobe Air, .NET and HTML5/JS (via an app packaging framework like PhoneGap) .
