onCreate在onActivityResult之前调用 - 启动新活动总是导致之前的acitity完成

Question

(我不是新手!,记忆力已足够.)

我正在研究android ICS(SDK 4.0),当我调用startActivityResult时,ai得到了奇怪的活动生命周期.

先前的每次都会破坏!!

当另一个活动被召唤到前面并重叠时,每次重叠活动 - 后面的活动 - 都会破坏,而不是在姜饼中看到(2.3.3).

下面的日志只是Activity1调用Activity 2的程序,并且只在Activity 2中按下后退键时返回结果.intent没有任何标志.这是我修改过的日志..

左边是在ICS(Gal Nex)中运行,右边是在Gingerbread(Nex one)中运行

Log when runned in GingerBread

 - Start ActivityStackTest1 and launched ActivityStackTest2 immediately.

_ActivityStackTest1 _ onCreate_calling new activity.. - starting activity for result

 - Pressed Back Key and returned to ActivityStackTest1.

_ActivityStackTest2 _ onPause_called..

_ActivityStackTest1 _ onActivityResult_returned somehow.

_ActivityStackTest1 _ onStart_called..

_ActivityStackTest1 _ onResume_called..

_ActivityStackTest2 _ onStop_called..

我在想错吗？是不是之前的活动应该等到孩子活动结束,而不是自己完成？

是否有任何问题改变了ICS后的生命周期？当你对它有所了解时,请注意我,这非常令人头疼.

解决了.确保"选项 - 开发 - 不要保持活动"未经检查.除非,你所做的所有活动都会变得奇怪.
