I’m ideally looking for someone to correct or enlighten me here, so please do!

The basic premise I want to put forward is that user interface components and libraries developed for the Android platform are not as easily reusable as standard Java Swing-based UIs. As opposed to simply linking a JAR file as you would in a J2SE or J2ME application, an Android developer must deal with the following files:

• An XML layout definition
• An entry in the R.java resource file
• The class definition(s)

It isn’t just the variety of files, but the process of integrating the third-party code into your application in a clean way that I am concerned with.

Am I missing something here? Is there an easy to just import a JAR into your lib, and load all of this up at once, possibly referencing a resource file and a separate set of layout XMLs within that JAR?

Maybe I need to go back and re-read the Building Custom Components section of the Android Developer Guide. Hmm.
