There is a easy way to protect a variable to be accesed only by one thread at once???

Programmer Question

Hi, i have a variable on my "SharedPreferences", that is accesed by two different threads, one in a service, and one in a activity.

There is a easy way to protect this variable to be accesed by two threads at once?

i need to protect this code:

            configEditor.putString("mylatitude", ""+currentLocation.getLatitude());
            configEditor.putString("mylongitude", ""+currentLocation.getLongitude());
            configEditor.commit();

i tryed with this but doesn't works:

Object LOCK = new Object();
                synchronized (LOCK){
                configEditor.putString("mylatitude", ""+currentLocation.getLatitude());
                configEditor.putString("mylongitude", ""+currentLocation.getLongitude());
                configEditor.commit();
                }

thanks
