might want to take a look at iOS too, all phone OS behave similarly, closing an app does not purge it from the memory, it goes into a sort of hibernation mode, it ensures when the app is relaunched it starts up quicker, humans are habitual people, the majority of peeps will only ever use a handful of apps, the app is only really purged when the memory is full and needs more room for a new app launch, and you have actually no control over the prioritization of which is purged and which is not, well anyways thats how the developers saw it....
