一句话：系统研究 Android 应用对抗进程查杀以延长存活时间的方法及其在真实世界中的普遍程度。
手机厂商采用多种方法杀死 Android 应用进程以降低电池消耗，这促使开发者设法延长应用的存活时间，论文将此类应用称为 diehard apps。尽管已有博客和文章介绍实现这一目的的方法，但此前缺乏针对该现象的系统性研究，更重要的是，人们对其在真实世界中的普遍程度知之甚少。本文围绕这一问题展开系统调查，梳理开发者可用来实现“不死”的手段，并评估此类应用在真实生态中的流行情况。摘要未报告具体方法细节与定量结果。
Smartphone vendors are using multiple methods to kill processes of Android apps to reduce the battery consumption. This motivates developers to find ways to extend the liveness time of their apps, hence the name diehard apps in this paper. Although there are blogs and articles illustrating methods to achieve this purpose, there is no systematic research about them. What's more important, little is known about the prevalence of diehard apps in the wild.
