It is also possible that you have a JAR file located somewhere in your project folders
(I had copied the Admob JAR file into my src folder)
and THEN added it as a Java Path Library.
It does not show up under the Package Explorer, so you don't notice it,
but it does get counted twice, causing the dreaded Dalvik error 1
