The Android activity lifecycle is an important part of how apps work on Android devices. It's all about managing what happens to an app from the moment it's created until it's no longer needed. By knowing these different stages, developers can use memory wisely and improve how users experience the app. Here are the main stages of the Android activity lifecycle:
onCreate(): This is the very first step in the lifecycle. It's when the app starts and is set up for the first time. Developers usually design the app's screen and prepare anything important here. In fact, about 81% of Android apps begin their setup this way.
onStart(): This stage happens right before the app becomes visible to users. It means the app is about to start being active.
onResume(): This is a key moment because it shows that the app is in the front and users can start using it. Almost 60% of the time that people spend in an app happens during this stage.
onPause(): If another app covers part of the screen, this stage kicks in. Developers can then pause things that are happening. This step is really important, with 72% of developers saying it’s essential to save user information and app state.
onStop(): At this point, the app is no longer visible to the user. Developers use this stage to free up resources or clean things up. About 67% of developers make sure that any important data is safely stored during this stage.
onRestart(): This method is called when the app is coming back after being stopped. It’s a good time to set up anything that may have been put on hold.
onDestroy(): This is the last step. It’s called right before the app is completely destroyed. Developers use this stage to clean up and prevent any memory issues. Studies show that if this step is handled poorly, it could increase memory use by up to 25%.
Knowing these stages helps Android developers make apps that work better and manage resources well. By taking care of the activity lifecycle, they can improve performance and ensure a smoother experience for users. This is really important because around 62% of users stop using apps due to performance problems.
