Is there a way to bind 2 java libraries with same namespace, same function names but different functionalities

Question

I am creating an android App to read BLE devices of specific manufacturer. I have 2 jar libraries for 2 different BLE devices, but since the manufacturer is same for both the devices, I don't know why, but they have kept the namespace same for both the libraries. Over and above the name of the functions are same but they behave differently. So the problem is when I use both the libraries together, either in same android java binding project or different, they clashes. Is there any way to force the libraries to get accessed through different namespaces?
