These are: onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy(). Therefore, ensure that you select Java as your preferred programming language.Īn Android activity goes through six major lifecycle stages or callbacks. In this tutorial, we will use Java to build an Android application. Then create a new project using the empty activity template. Let’s now dive in and discuss different Android application life-cycles and see how we can implement them.įirst, ensure that Android Studio is running on your computer. Prior knowledge on how to run and use Android Studio Logcat.A good understanding of Android application development.This application will be life-cycle aware to understand which callback is being executed. We will develop an Android app that showcases where various activity lifecycle callbacks take place. We will discuss all the states that apply in an android activity lifecycle. In this tutorial, we will explain different Android application lifecycle callback states. This allows you to implement the right callback to handle the situation. In this case, you have to know about the activity lifecycle. Let’s say your application is running in the background, and you wish to save some data. You can override these methods to do a particular operation to give the right output to users. It crosses through various stages from when a user opens and exits an application.Īn application’s state helps you manage when a user opens an activity, pauses, resumes, stops, and destroys it.Ĭallback methods manage these states. As a result, we can do proper operations at the right time and avoid crashes and other bugs.Īn Android application has a lifecycle. The Android lifecycle helps developers understand which states activities go through when a user navigates through an app.
