can you change between GPS_PROVIDER and NETWORK_PROVIDER at runtime?

The situation is this, every so often I send the user's location to a small test table, the location I get it through the gps, if this was not activated at the start of the service I would get the location through NETWORK_PROVIDER, all it works perfect the detail here is that if I'm using the gps and I deactivate it does not send the location of the NETWORK_PROVIDER, I think it's because the service's onCreate is created like this, but at the time of execution I can not change what changes between a provider or another
