Why does my apk app crash with the upgraded Unity?

While I was building my android mobile app, everything was working just fine. For some reason, since I’ve upgraded to the newest version of Unity(version 4.5.3f3), my app crashes constantly. It stays running for about 1 to 2 minutes before it crashes. Sometimes I get the error “An unexpected error has occurred,” but that is rare. Can anyone please help me because it’s making it impossible to beta test.

I saw two problems when I looked through your logcat file. The big one is this:

E/NativeActivity( 2054): channel '40a3d758 com.facebook.VoyageAroundTheWorld/com.unity3d.player.UnityPlayerNativeActivity (client)' ~ Failed to receive dispatch signal. status=-11

There’s a message thread discussing this problem, and a potential solution is at this link. I can’t guarantee it will work, but it’s a start.

The smaller problem is the lines that state “The referenced script on this Behaviour is missing”. Presumably you have a few missing scripts. Hopefully these wouldn’t cause Unity to crash, but they’d be worth fixing anyway.
