Android is a popular mobile operating system developed by Google, and it is written in the programming language Java. However, it’s not just Java that is used in Android development; C and C++ are also important components. Java is used for the development of the Android framework and the Android app development, while C and C++ are used for the development of the lower level components, such as the Android kernel, the Android libraries, and the device drivers.
