Android Activity Class

Android Activity Class


An Android activity is a self-standing component of an Android application that can be started, stopped, paused, restarted, or reclaimed depending on various events including user-initiated and system-initiated ones [Ref. 4]. An Activity class is a special Java class and every Android app must have at least one. It is the part of the code where our app will start when it is launched by the user, and this also handles any interaction with the user. But who or what is calling onCreate!? The answer to this mystery is that Android itself calls onCreate in response to the user clicking on the app icon to run the app [Ref. 1].
