[android-developers] instantiation of main activity

2012-07-27 Thread peter gottlieb
I have gone through several stages in the development of an app, compiling 
and executing just fine.  After my latest increment of code the app builds 
fine, but crashes with the following message in the Log:

unable to instantiate ActivityComponentinfo {}: 
java.lang.NullPointerException.

My conclusion is that all of a sudden the Android system code is crashing 
before even getting to any of my code, which is also supported by the  
fact  that if  I comment out all of my app-specific code in the onCreate 
function, I still get the crash.  However, testing several of my other apps 
shows them building and executing just fine.

Please help.
