 I had written landscape app. which use surface view and camera.
It works fine mostly.

However, The weird thing is that the app sometimes (once a 5~6 times)
freezes when I started it.
The DDMS spits out following log.

09-02 10:58:29.191: WARN/WindowManager(1132): App freeze timeout
09-02 10:58:29.201: WARN/WindowManager(1132): Force clearing freeze:
AppWindowToken{43b4ea00 token=HistoryRecord{4386bcc0 {}}}
09-02 10:58:29.251: WARN/SurfaceFlinger(1132): timeout expired
mFreezeDisplay=1, mFreezeCount=0

The following lines are added in the manifest.xml


I have struggled but have no progress.

Any Ideas?
Thnks in advance.

 What is your app doing in the debugger?  That message is saying that the
window manager gave up waiting for the app to draw all of its windows before
unfreezing the screen in the new orientation, so for some reason you aren't
getting your windows/surfaces drawn.

 I had checked my app. again and I found that the onCreate function
sometimes take more than 5 sec. to complete.
After modify the onCreate function, the problem is gone.

I installed Eclipse with ADT plugin (latest version). Doing so, I now
end up in a no longer working Eclipse. It states
"An error has occurred. See the logfile..."

2. Unable to figure out what WindowManagerservice and PhoneWindowManager difference

Possibly separate Policy from Mechanism

WindowManagerService extends IWindowManager.Stub: System private
interface to the window manager.

WindowManagerPolicy interface: supplies all UI-specific behavior of
the window manager.  An instance of it is created by the window
manager when it starts up, and allows customization of window
layering, special window types, key dispatching, and layout.
