Android is an open source operating system for mobile devices like smartphones, tablets, and computers. The operating system is developed by the company Android which was then taken over by Google. Android is based on the programming languages Linux and Java. Google continues to develop Android, so there are several versions that all get a number and a working title. For example, titles like KitKat, Marshmallow and Nougat are given to their respective versions.
The Android operating system is now being integrated into mobile devices by a large number of brands. Some of these well-known brands are Samsung, Huawei, Sony, and LG. All devices are fully powered by Android, which means that when applications are being developed, they are built specifically for Android.
Building apps or applications for Android can be accomplished in the open source development environment SDK (Software Development Kit) or Android Studio. This environment is fully accessible for everyone, with a simple download anyone can start developing applications.
Apps are constantly updated for new versions of Android for security reasons. Additionally, applications are updated to improve user-friendliness, for example by modifying the interface or updating modules. The version number can be found in the app or the Google Play Store, where all applications for Android can be found.
