Android StatusBar and Notification View Summary

Brief overview of the history of the status bar and notification view(quick settings for 4.2+) in android.

Status Bar history:

1.5 – 2.2.2: com.android.server.status.StatusBarView

2.3 -2.3.7: com.android.systemui.statusbar.StatusBarView

4.0.1 – 4.2.2:             com.android.systemui.statusbar.phone.StatusBarWindowView(from 4.1.1) -> com.android.systemui.statusbar.phone.PhoneStatusBarView

there is also


Notification +  Quick Settings View history:

1.5 – 2.2.2: com.android.server.status.StatusBarService.ExpandedDialog
2.3 – 2.3.7: com.android.systemui.statusbar.StatusBarService.ExpandedDialog
4.0.1 – 4.1.2 :         com.android.systemui.statusbar.phone.PhoneStatusBar.ExpandedDialog
4.2 – 4.2.2: com.android.systemui.statusbar.phone.NotificationPanelView  + com.android.systemui.statusbar.phone.SettingsPanelView
so basically before 4.2 the status bar and notification view were 2 different root views.
From 4.2 we have only com.android.systemui.statusbar.phone.StatusBarWindowView as a root view and then both notification and settings on different child views.
For non tablets it can be that we don’t have com.android.systemui.statusbar.phone.SettingsPanelView but on top of NotificationPanelView we can have:
->  com.android.systemui.statusbar.phone.QuickSettingsContainerView
->  com.android.systemui.statusbar.phone.QuickSettingsTileView (for every item)
