Question

I have a service running on my android application, the service is a socket class that has to run through the whole application, i create it when my first activity loads.
How can i get an instance of this socket class so that i can call a function in this class.

For example
//how can i get an instance of the running service?
MyService s = getService();
s.writeDataToServer("hello");

The Android Interface Definition Language (AIDL) is the correct way to connect to a service.
