I would suggest using the Android framework to create applications for it. The J2ME runner is incomplete and will always be incomplete. Google is not going to guarantee that this J2ME project is supported in future releases, and it may just stop working with any firmware update.
Keeping this issue aside, you'd better use the completely different and better elements of the applications that Android provides than limit yourself to what is provided with this J2ME runner.
