I have an android library in the form of an eclipse project that I want to integrate with unity3d. I know I can make a jar from eclipse and drop it in unity's plugins/android folder. However as I understand it that necessarily strips out the resources from the project.

If I export the unity game to an eclipse project, I can right-click and add the android project as a library. However I don't like this approach because it doesn't fit with our current automation process - which basically just script's unity's build dialog.

I'd like a way to tell unity that I want this eclipse project linked as an android library on export. Does anyone know a way to do that, or how to pack the resources into the jar or another way of getting this stuff to talk?

One possible way to go is using Unity's Build Player Pipeline. Depending on the platform you are working on you then have to set up a shell script or do your stuff in C#.

It's some year ago that I were a Java/Eclipse expert as I am working on iOS now. The Android Developers page shows some way to manipulate projects via command line.

Maybe the better way to go is using Eclipse switches like --import (s. 1st answer in Create an Eclipse project on the command line? and the link provided) but on the other hand I can't find the switch in the help pages.

Well, not really a bounty answer but maybe some inspiration :-)

The only real answer I've found is that in 4.2, you can drop an eclipse project in plugins/android and it will be linked correctly. Just have to hang on I suppose. :-/

  • ...and now we're on 4.3 and this process works fine.

  • can you elaborate what you do? Do you drop your entire project into the plugins/android folder (so that you have a structure plugins/android/MyProject/res, for example), or do you copy the res folder straight into the /plugins/android folder (so that you have a plugins/android/res structure)?

  • the former. the entire project into the plugins folder.
