Thanks for that info, it might help me to achieve what I want. The IM app after discovering all the plugins by using the strategy you mentioned on your first reply, caches the resources of each plugin on ImProvider. I would like to transfer the responsibility of caching from IM to plugins in order to save some time and memory. I have to think a little bit more. but I'm considering of turning plugins also into content providers. I guess I am asking too much if I can know/control in what order content providers running in the same process are started :)
