Android software development is the process by which applications are created for devices running the Android
operating system. Google states that "Android apps can be written using Kotlin, Java, and C++ languages"
using the Android software development kit (SDK), while using other languages is also possible. All non-JVM
languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be
supplied by tools, likely with restricted API support. Some programming languages and tools allow
cross-platform app support (i.e. for both Android and iOS). Third party tools, development environments, and
language support have also continued to evolve and expand since the initial SDK was released in 2008. The
official Android app distribution mechanism to end users is Google Play; it also allows staged gradual app
release, as well as distribution of pre-release app versions to testers.
