After a discussion with Diego, we decided to revert the singleton implementation of the class, because it is not actually a real singleton, as you can still instantiate it from the same package (the constructor is protected), because we want the connector not to be a final class. So, we decided that to hold an instance in order to be available for multiple Activities using it, create a "Holder" class that has a static field that stores the OpenErpConnect instance.
