For something like that, it's not terribly special. Here is the recipe I use: Step #1: Create an Android project for the reusable library. Step #2: Create the library, plus a sample app for testing. Step #3: Add a "jar" task to the Ant script to package up the compiled classes in JAR format. Step #4: Reuse that JAR the same way you would reuse any JAR in Android (i.e., put it in libs/ of the target project, and if using Eclipse add it to the build path).
