I am trying to login into the app but after the login is success and it is about to go to next screen, it restarts. Following is the exception that I guess would have caused this, as there is no other exception. 

11-14 15:09:54.841: W/WindowManager(643): Failed looking up window

11-14 15:09:54.841: I/WindowManager(643): WIN DEATH: null

Can anyone tell, what does it mean and if possible how to correct it.

This may be caused by calling a system API that is not available on your target device. I ran into this issue then trying to call ActivityManager.MemoryInfo.totalMem on a 4.0.x device. I didn't get any compile errors as I was targeting 4.2.2 and ActivityManager.MemoryInfo.totalMem was added in API16 (4.1)
