Note: The problem described here seems to be only for Mac OSX & JDK 7 is installed.
After failing to upgrade Android SDK tools to version 23 because of dependency issue (documented at https://code.google.com/p/android/issues/detail?id=72912), I was searching for a solution for the following error message.
One suggestion was to download a fresh copy of eclipse directly from http://www.eclipse.org, and do a fresh install of Android SDK tools (from repository : https://dl-ssl.google.com/android/eclipse/)
After downloading eclipse, and installing Android SDK, I decided to create a basic "HelloWorld" android app, to see if everything is working fine - and came across the following error, when clicking "Finish" button on android project creation wizard:

Errors running builder 'Android Resource Manager' on Project java.lang.NullPointerException
Clicking "Ok" will still create the project, but will not have any activity code generated.
To resolve the issue, do the following:

To resolve the issue, do the following:
- Go to your eclipse directory and find "Eclipse.app" file. Just to be on safe side, back up this file somewhere (Just the Eclipse.app file).
- Right-Click on "Eclipse.app" file, and select "Show Package Contents"
- Once inside package, go to Contents-->MacOS, and open "eclipse.ini"
- Just before the "-vmargs", add the following:
-vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Commands/java - Here is my "Before" and "After" eclipse.ini file
Before After - Run eclipse again, and you should be able to create the project without any problems.
