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--------------------------|binderActivityManagerNative.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）|binderActivityManagerService.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()
