Now for every operating system, some applications can run on it to perform specific tasks. Similarly, for Android Devices, we have Android Apps that can run on them to perform specific tasks. - -Evident enough that the software engineering field for developing such apps is known as Android App Development. -The official language for Android development is Kotlin, but Java is still used in many famous courses and many projects, so you are free to use any of them. - -## Installation - -### Android Studio - -Android Studio is the official Integrated Development Environment (IDE) for Android app development.
