*- I've made the jar approach work before, and intuitively statically linked code shouldn't really be doing anything as long as you're not making references to the resources classes. * I was hoping someone would say this. Thankyou. I will try to paste the code I was trying in a while and then hopefully you could identify any changes. And yes I'm certainly not using resources.
*- Why do you think you have to distribute code with an Android library project? You can just remove (everything in) the src/ directory and distribute it that way, no source required. * - Now given that you have got the jar approach to work, I will hold on to the Android Library approach for the moment.
