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 and distribution of pre-release app versions to testers.
