如何做机器人＆QUOT;程序锁＆QUOT;应用程序的工作？ [英] How do android "app lock" applications work?

问题描述

我尝试使用Google，并期待在计算器一样好，但我似乎无法找到任何令人满意的答案，如何在应用程序锁应用程序（例如：ZDBox，应用程序锁等）工作。 是否有在后台运行，不断轮询，以查看是否应用程序启动并试图杀死它的服务？或者是有没有办法拦截推出意图为新的活动？

I've tried googling, and looking on stackoverflow as well, but I can't seem to find any satisfying answer as to how the "App lock" applications(eg: ZDBox, App Lock, etc..) work. Is there a service that runs in the background continuously polling to see if the app is launched and tries to kill it? Or is there a way to intercept launch intents for new activities?

推荐答案

有在后台运行，以读取活动堆栈的服务。如果发现新的活动，将启动passwordActivity

there is a service running in the background to read the activity stack. if find new activity, will start the passwordActivity
