Also, an event like onInit() would be useful in my scenario, as I just want to have the action start at first. onDestroy() is not called until other apps need more memory. 回答1: If your activity is the last in the stack then detecting a back button with onKeyDown would solve 1/2 of this The home key is a little trickier, there is no absolute method but you could do something

Android启动模式分为四种，分别为：standard、singleTop、singleTask、singleInstance stander 标准启动模式: 这是Activity默认的启动模式，也是逻辑最简单的一种，只要Activity使用这种模式进行启动，系统会不管三七二十一，直接create一个Activity实例出来，然后加入到Task顶。 2. singleTop: 这中启动模式和standard的最大区别，就是它在启动时会检查Task顶部是否已经存在该Activity实例，if 存在 则重用已经存在的实例，else 重新创建一个activity实例并加入task顶部。 3.singleTask 这种启动模式相对于上面两个，就比较复杂。如果activity以这种模式启动，会执行下面的流程： a)系统会先为这个Activity加上Flag_new_task 的标签 b)获取该activity的 taskAffinity属性（该属性默认为应用程序的包名） c)检查系统中是否已经存在taskAffinity属性值所对应的Task： ！)如果存在该Task：则先检查该Task中是否有目标Activity的实例，if存在，则清空该实例以上所有的Activity实例，将该Activity实例放在Task顶部。如果不存在，则重新创建一个该Activity的实例，并且加入到该Task中
