Android is a mobile operating system made by Google. It is available for devices with a CPU that can run the Android OS and a display that supports graphics. Some common devices that use Android are smartphones, tablets, and smart TVs.
Android apps are written in the Java programming language. They use the Android platform to interact with hardware, display content, and manage resources.
Android uses the APK (Android Package) ormat to distribute applications. APK files are compressed and designed to work with Android devices.
Android uses the Android Runtime (ANR) o help applications run on devices that do not have the same software version as the device on which they are running.
Android uses the Dalvik Virtual Machine to run applications. The Dalvik Virtual Machine is a runtime environment that runs Android applications on devices with an ARM processor.
Android uses the Build Type feature of the Gradle build system to control how the Android application is built and deployed. The build type can be set to debug, release, or profile.
