Android Activity启动模式分析

最近看了android activity的启动模式，四种启动模式各有不同，写了份test测试不同启动模式activity生命周期的变化。

模式1、正常连续启动standard activity

  main-->standard-->standard

10-29 00:02:50.929: I/System.out(22132): BaseActivity---->onCreate**
10-29 00:02:50.959: I/System.out(22132): BaseActivity---->onStart**
10-29 00:02:50.959: I/System.out(22132): BaseActivity---->onResume**
10-29 00:02:53.119: I/System.out(22132): BaseActivity---->onPause**
10-29 00:02:53.149: I/System.out(22132): Standard1---->onCreate**

10-29 00:02:54.369: I/System.out(22132): Standard1---->onStop**

模式2、连续启动singleTop activity

main-->singleTop-->singleTop

模式3、交替启动singleTask activity
main-->singleTask-->standard-->singleTask
