Any Android app could lose its UI state due to activity or process recreation. This loss of state can occur due to events such as Configuration changes (The activity is destroyed and recreated unless the configuration change is handled manually) or System-initiated process death -The app is in the background and the device frees up resources (like memory) to be used by other processes. In this session we will learn how to handle process death in Android, being able to remain user activity even after the app was killed in the background by the system.
