Yup, you're right - there are indeed Eclipse files inside the folders. I guess I was confused by the different names in [1] than those that result [2] from importing to an Eclipse workspace - after which I see 13 projects in both cases. So please ignore my previous remark. I don't think introspection is a good solution, hence you will need to > change how the sca reads the info about each service and also services > implemented for JVM would need to be adapted to run on Android.

Thanks for the advice it helps me to focus in the right direction :-) Now, a summary of what I've done up to now: Per the reply I received on the Android Developers list [3] I started using retrotranslator on JAR's instead of class files. For this I created a big JAR file with all the Tuscany modules (including those you modified for Android). I translated this big JAR (around 15MB) with retrotranslator [4]. Then I created a new workspace with only calculator-android and android-jdk-classes as projects and added the translated JAR as an external library for both projects. This resulted in errors [4] from the Android build process. To work around these errors I decided to take a different approach and copy all the jar files contained in the individual modules to a separate folder and then run retrotranslator on each JAR. The jars are found inside the target folder of each module and are named as shown below: tuscany-<NAME>-incubating-SNAPSHOT.jar >From this I found that only the SCA modules have these JAR files inside their respective target folders, whereas the Android modules I downloaded from [1] don't have these files at all. So I decided to keep the Android modules [2] and add the translated JARs as libraries where needed to have the workspace build with no problems. If I get this running I would look into creating JAR files from the Android modules and then return to only having calculator-android and android-jdk-classes as projects and the rest as JAR's added as external libraries. If this works out I could then look into seeing which JAR's are important and which are not, in this way reducing the total memory footprint and coming up with a "lightweight mobile SCA core/runtime." Please let me know your thoughts on these efforts.
