you could still use onCreate/onDestroy. Just override the onRetainNonConfigurationInstance method. This method will be called before onDestroy. If this method is called, remember this fact by setting a boolean to true.
Then in the onDestroy, if this boolean is true, a configuration change will happen: don't shut down the connections. If this boolean is false, then a real destroy takes place and shut down the connections. In the onCreate, you can call getLastNonConfigurationInstance() to see if this is a brand new creation or just the start of a configuration change. You could even program the onRetainNonConfigurationInstance to return an object holding your connections. Then in your onCreate, you call getLastNonConfigurationInstance to get your connections. If the call to getLastNonConfigurationInstance is null, then your activity was started from 'scratch'.
