Obtaining, Installing, and Removing of Mobile phone Application
Mobile device apps are obtained from an outside source such as Google Play, Apple’s App Store (or through iTunes), Microsoft Store, Amazon’s Appstore for Android, and a host of other content sources. There are other ways to get an app: manually install (side load), use a USB cable (commonly requires a file management app), use your storage media and a media reader, use an app such as Bump to transfer an application (or photos), or use a quick response (QR) code between two devices. Note that whatever method you use to install an app, you must ensure that the app is from a trusted source or a trusted app developer. Be sure to see what permissions are given when an app is installing.

Because Android is open source, the exact steps may vary. Also, Apple IOS and Windows for mobile devices are constantly being updated/upgraded.
Two important terms related to Android apps are APK and SDK. An Android application package or APK is the file format used to distribute and install Android apps. So if you download an app, it is an APK file. A software development kit (SDK) is a set of tools (application programming interfaces [APIs], documentation, programming tools, analytic tools, sample code, etc.) used to develop an app for a specific mobile OS or platform.
