GetAppLifecycle class

States that an application can be in.

The function below describe notifications from the operating system. Applications should not expect to always receive all possible notifications. For example, if the users pulls out the battery from the device, no notification will be sent before the application is suddenly terminated, along with the rest of the operating system.
