以上结论有错误，onPause和onStop一般都是成对出现，锁屏会同时调用，非全屏dialog弹出时，两个都不会调用

以上的结论有错

是呀挺好记的。

基本上可以分3对，ocreate对应ondestroy 销毁跟创建， onStart对应onStop 可见与不可见都不能操作，onResum对应onPause 都可见 前者可操作后者不可操作。

说得通俗一点就是：onPause就是你看得见，但是无法操作；onStop就是你看都看不见。

Generally, you should not use onPause() to store user changes (such as personal information entered into a form) to permanent storage. The only time you should persist user changes to permanent storage withinonPause() is when you're certain users expect the changes to be auto-saved (such as when drafting an email). However, you should avoid performing CPU-intensive work during onPause(), such as writing to a database, because it can slow the visible transition to the next activity (you should instead perform heavy-load shutdown operations during onStop()).
