Description: The ‘onDestroy’ method in Android is a crucial component of an activity’s lifecycle. It is invoked when the activity is about to be destroyed, which can occur for various reasons, such as the user finishing the activity or the operating system needing to free up resources. This method provides an opportunity to perform cleanup tasks, such as releasing resources, saving data, or stopping background processes that are no longer needed. It is important to note that ‘onDestroy’ is not always called, as the system may destroy an activity without invoking this method if memory needs to be freed. Therefore, developers must be careful when implementing logic in this method, ensuring that any critical tasks are performed in earlier lifecycle methods, such as ‘onPause’ or ‘onStop’. In summary, ‘onDestroy’ is essential for ensuring that activities in mobile applications are managed efficiently and that resources are released properly, thus contributing to the stability and performance of applications.
