从钛DOC ：
不保留活动在开发人员选项菜单。当此 启用选项，Android操作系统将尽快销毁活动 它被停止。它的目的是帮助开发人员调试他们的应用程序。对于 例如，它可以模拟的机器人会杀死活动的情况下， 在由于内存pressure背景。在正常使用时，它是不 建议打开该选项，因为这可能会导致意外 对应用程序的问题，如死机，强行关闭和重新启动。
Don't keep activities under the Developer Options menu. When this option is enabled, the Android OS will destroy an activity as soon as it is stopped. It is intended to help developers debug their apps. For example, it can simulate the case that Android will kill an activity in the background due to memory pressure. In normal use, it is not recommended to turn this option on because this may lead to unexpected issues on the apps, such as freezes, force closes and reboots.
这听起来像它基本上可以帮助测试确定性如何在操作系统将其关闭你的应用程序的行为，由于某种原因（内存不足等）。
It sounds like it basically helps testing deterministically how your app behaves when the OS shuts it down due to any reason (out of memory and so on).
所以，这回答了点1点2：是的，我想：）
So, this replied to point 1. Point 2 is: Yes, I guess :)
