Unable to execute dex: Multiple dex files define
Conversion to Dalvik format failed with error 1
UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lcom/cyberwalkabout/common/DistanceUtils;
We have been using multiple project libraries for months, but now including them causes a problem as some of them are referenced more than once.
SOLUTION is listed here: http://ukitech.blogspot.com/2012/06/javalangillegalargumentexception.html
Other problems encountered:
Updates (Android ADT 14) in Eclipse Indigo that introduced these problems:
switch() to if-then
Among many, many things that went wrong today this one was was annoying because of many places I had to change, but at least quick to fix.
Android ADT 14 decided that it does not like to use R.id.reference as a parameter to switch statement and it had to me changed to if-then.
So all of the switch statements had to be converted to if-then. Thankfully there is a shortcut for that (command-1).
