从中我们不仅能看出问题出在哪儿，而且还可以借此了解下应用程序初始化执行流程，因为这个问题是在应用刚启动的时候出现的，重点执行流程是：

（为便于阅读，我已经将日志顺序倒过来，和执行顺序保持一致）

com.android.internal.os.ZygoteInit.main(ZygoteInit.java:629) com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:739)java.lang.reflect.Method.invoke(Native Method)  android.app.ActivityThread.main(ActivityThread.java:5438) android.os.Looper.loop(Looper.java:148) android.os.Handler.dispatchMessage(Handler.java:102)android.app.ActivityThread$H.handleMessage(ActivityThread.java:1349) android.app.ActivityThread.access$900(ActivityThread.java:153)android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2483) android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2376)android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1108)android.app.Activity.performCreate(Activity.java:6303)com.swipefresh.MainActivity.onCreate(MainActivity.java:17)

可以看出程序是从ZygoteInit.main 629行开始，最终到MainActivity.onCreate。这样比首先在源码里直接分析流程快多了。

那么有其他方法可以帮助我们分析应用启动流程吗，答案是有的, Thread.dumpStack()。
