Android/Java referenced library issues - NoSuchMethodError

I have been getting a NoSuchMethodError from an external library that I am using in Eclipse. I'm trying to run a parser that gets VCard data and decodes it, using this library, which ships with all its dependencies (including the packages mentioned in the logcat below). I have added all of the dependencies to my References Libraries in Eclipse via Build Path -> Add External JARs. However whenever I run my code, I get:

Thing is, I have checked the org.apache.commons.codec.binary package in my References Libraries and the Base64.decodeBase64 method certainly exists. What gives?

From the answers to other similar questions, it would appear that Android includes the 1.2 commons codec library which must appear first on the classpath. That version does not include the byte[] version of the decodeBase64 method.

One possible solution would be to change the EZVCard source (since it is open source) to call the String based method instead.
