Android hot 'n' read - #1 : Preserving your android app state

Many developers know how to survive screen rotations using ViewModel or rememberSaveable, but the bigger questions remain: Why does state get lost in the first place? Why is ViewModel often the go-to solution, and is it the only one? What about other scenarios, like process death or user-initiated closures?

Unlike desktop or web environments, Android apps run on a wide range of devices with different hardware capabilities, varying screen sizes, and limited resources like memory and battery. Moreover, the Android operating system is designed to be highly dynamic, frequently creating and destroying activities and fragments to optimize resource usage and preserve battery life. This means that your app's state can be lost or reset at almost any time if not managed properly.

In this first release of Android Hot and Ready, Preserving Your Android App State, we share insights and practical strategies for managing state in your Android apps. From handling configuration changes to preparing for process death, we've covered a range of solutions to keep your app’s state alive and ensure a great user experience.
