does exporting the libraries have something to do with JIT and compiling it into dex at runtime? I'm trying to make sure that my Android application has the smallest possible binary so that upgrades are not to big. Maybe someday Google will make upgrades partial instead of the whole APK.
Just now noticing these questions as the new ADT 22 has you manually export the "Android private libraries" now which used to be the libs folder and it would automatically export it anyway.
