yeah. its one of those buttons that if you used it. you loved it because it was the only easy way to simulate real process death. all other dev options on the device itself are kinda wonky (process limit, activity limit, etc)
In the meantime I've been using the venom library as it has a notification where you can click to kill your process.
its kinda funny. i took a bunch of courses on android dev, and even the udacity google/android courses. and all of them let you know about process death and how you can't guarantee that your app will survive once its backgrounded. and like. someone no one cares that this is a thing. maybe i shouldn't either? /shruggie
