http://blog.csdn.net/luoshengyang/article/details/6689748

简要整理：

context.startActivity()
|
Activity.java.startActivity()
|
Instrumentation.java.execStartActivity()
|
{当前应用程序主线程（context）—>binder,RemountBinder}
|
-------------通过binder，流程进入activityManagerService--------------------------
|binder
ActivityManagerNative.java
|
ActivityManagerService.java.startActivityMayWait()
|
{通过packageManger获得目标Activity的package，classnane}
|
ActivityStack.java.startActivityLocked()
|
ActivityStack.java.startUncheckedLocked()
|
{检查是否需要返回（即是否startActivityForResult()？），检查task是否存在（LauncherMode==Single_instance?）}
|
{新建TaskRecord.java}
|
{检查目标activity是否已经Resumed}
|
否，将当前Resumed界面标记为pause
|
ActivyThreadNative.java.ApplicationThreadProxy.schedulePaused()
|
ActivityThread.java.schedulePauseActivity()
|
ActivityThread.java.performPauseActivity()-->Activity.onPause()
|
ActivityManagerNative.activityPause()（通知am暂停界面）
|binder
ActivityManagerService.java.activityPause()
|
ActivityStack.java.activityPause()
|
ActivityStack.java.startSpecificActivitylocked()
|
{查询进程信息}
|
AcivityManagerService.startProcessLocked()-->fork()新进程
|
ActivityThread.java.main()
|
ActivityStack.realstartActivitylocked()
|
ApplicationThreadNative.java
|
ApplicationThread.java
|
ActivityThread.java.handleLaunchActivity()
|
ActivityThread.java.performLaunchActivity()
|
Activity.onCreate()
