What I'my trying to do is to load already deployed smart contract and interact with it. The problem is that after my credentials are being created properly, the error is being catched but the message is empty. I' m new to adnroid, and totally don't know how to make it work. I will upload more infos but don't actually know what are exactly needed. I would be very greatfull for help.
The problem was actually not with the Project.load method but with .send() when using Web3j on android you have to use sendAsync().get() to make it work. So the problem is solved.
