以上結論有錯誤，onPause和onStop一般都是成對出現，鎖屏會同時調用，非全屏dialog彈出時，兩個都不會調用

以上的結論有錯

是呀挺好記的。

基本上可以分3對，ocreate對應ondestroy 銷毀跟創建， onStart對應onStop 可見與不可見都不能操作，onResum對應onPause 都可見 前者可操作后者不可操作。

說得通俗一點就是：onPause就是你看得見，但是無法操作；onStop就是你看都看不見。

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()).
