为了更直观的看到window的添加，我在WindowManagerService.java中添加如下log，这样可以看到每次添加窗口的细节
+++ b/base/services/core/java/com/android/server/wm/WindowManagerService.java@@ -1424,7 +1424,13 @@ public class WindowManagerService extends IWindowManager.Stub public int addWindow(Session session, IWindow client, int seq, LayoutParams attrs, int viewVisibility, int displayId, Rect outFrame, Rect outContentInsets, Rect outStableInsets, Rect outOutsets, DisplayCutout.ParcelableWrapper outDisplayCutout, InputChannel outInputChannel) { /********************************/ win.attach(); mWindowMap.put(client.asBinder(), win);-+ android.util.Log.v("lishuo","*** ADD client.asBinder :" + client.asBinder().toString());+ android.util.Log.v("lishuo","*** ADD windowState :" + win.toString());+ for(IBinder key:mWindowMap.keySet())+ {+ android.util.Log.v("lishuo","client.asBinder :" + key.toString());+ android.util.Log.v("lishuo","windowState :" + mWindowMap.get(key).toString());+ } win.initAppOpsState();一，重启抓取log。

二，进入应用时窗口的添加，实际操作是在桌面点击设置，观察窗口的添加动作
（1）点击-->进入一级设置界面。
可以看到此处有两次的添加，第一次为“Splash Screen com.android.settings”，第二次就是真正显示的设置界面“com.android.settings/com.android.settings.Settings”

三，Dialog和Toast的添加
（1）Dialog,此时添加的是“将屏幕投射到设备上”的dialog
