Cordova (the underlying framework that Icenium uses currently) does nothing special to preserve the application state. It works the same way as any Android application. If state is not preserved it means that the device you are using removes the application from its operating memory.
If you need to preserve anything you can use this event to record any information you need into local storage and then on this event to load it back into memory.
I hope this helps.
All the best,
