Mobile apps on Android devices work by using the Android operating system’s APIs to access the device’s hardware and software resources. Android apps are typically written in Java and run on the Dalvik or Android Runtime (ART) virtual machine, which provides the necessary runtime environment for executing the app’s code.
When an app is launched on an Android device, the operating system creates a process for the app and allocates memory for it to run. The app then interacts with the device’s APIs to access its various features, such as the camera, GPS, network connectivity, and more. The app can also make use of services provided by the Android framework, such as background tasks, notifications, and inter-app communication.
Overall, Android provides a comprehensive and flexible platform for developing and running mobile apps, enabling developers to create a wide range of apps for different purposes.
