Re: [android-developers] Re: how to add --core-library to Eclipse ?
Hi Marco, Could you share the details of your solution with me ? I'm trying to build a very specific that is intended to run on only one device. I need the javax.naming classes required by a library... and whatever the warning I just want to give it a try ;) Thanks, Thomas.

It seems like there's a lot of legacy code that wants to use java.beans, since we regularly hear about people wanting to import something-or-other that depends on it. The problem is that you put us out here in a bind: we can't use your classes (because they are not in the SDK) and you won't let us use our edition of those classes. I sympathize with your cause, but there are solutions: In the short term, I recommend repackaging the classes in question so they are in your app's package namespace. It's a minor pain, I admit, but it will solve the problem. You might also investigate whether you can excise the references to java.beans entirely from the code you import. In the long term, Android should probably provide at least a partial implementation of java.beans. I don't believe it is feasible to provide a full implementation, as some classes in java.beans reference UI classes in java.awt that aren't reasonable to have on Android within the foreseeable future. I would recommend the --core-library dx error message have a link to some documentation page where this gets spelled out, so we know what to expect. In particular, a list of the prohibited namespaces would be handy, so we don't have to just guess what we can and cannot use. Glibly, java.* and javax.*. dx is actually somewhat lenient with regard to javax, since the nominal mandate for that top-level package is that it is for extensions which are often packaged separately from the runtime. However, I would always err on the side of repackaging. That said, you can find the actual list of verboten javax packages in the source for dx. And *that* said, for your convenience, here is the list as it currently stands: accessibility crypto imageio management naming net print rmi security sound sql swing transaction xml I ended up augmenting the error message yesterday (in an Android- internal branch for longer-term work, not Cupcake), though it perhaps could still use a bit more work.

I managed to work around with activitycreator and ant scripts (build.xml), but this way it takes too long. Where can I configure this? As far as I know, it is not currently configurable. Given that you posted this to android-developers, I assume you are trying to develop an application and are not working on the platform code per se. If so, then --core-library is almost certainly *not* what you want to do. This aspect of dx is written to protect app developers from inadvertently introducing platform incompatibilities which will cause their apps to fail to operate. In particular, dx rejects the definition of classes in namespaces which are already used by classes in the standard boot classpath or are likely to be defined in future incarnations of the platform. Maybe if you can be a bit more specific about what you're actually trying to accomplish, someone here can provide you a suitable alternative. To save the curious some trouble, here's the error message Marco got: Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the --core-library option to suppress this error message. If you go ahead and use --core-library but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message. Maybe it needs some further wordsmithing. -dan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
