Android: Passing variables to an already running service

Question

I am having issues passing a value from an Activity to an already running service. I was wondering what the best approach to take would be? Adding extras wont work as I believe

Answer 1

If your service is not an IntentService, you can call startService(...) as many times you want. The service will run the first time but next calls will result in new onStartCommand() calls with the new extras you need.
