This is a recently problem with the new SDK for Android.
Now Android SDK uses the ANT convention when import external jars to the apk package, the external jars must be on the "lib" folder and the SDK ever will export the jars from that folder. My problem is when i add my jars and run my project i get this message: trouble processing "javax/transaction/HeuristicCommitException.class": > > Ill-advised or mistaken usage of a core class (java.* or javax.*) when not > building a core library. > > This is often due to inadvertently including a core library file in your > application's project, when using an IDE (such as Eclipse).

But i can't found that Android.jar, except the Android librar that can't be removed. This issue about import libraries to android it's making me mad because my application was working very good. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
