AndroidObservable.fromSharedPreferencesChanges(): listener get GC'ed about rxandroid HOT 3 CLOSED

Possible workaround is to keep strong reference to the subscription.

I would prefer not to move listener to Operator because in this case we create lifecycle where it should not be. We can not fully solve this issue such way. In any case we should keep strong ref to listener, keeping it explicitly in operator, or implicitly in subscription.

Totally agree with @Yarikx. fromSharedPreferencesChanges implemented properly and holds a reference to the listener as long as it's needed. The api consumer is the one who responsible for keeping a reference to the Subscription and canceling it when necessary.

Thank you for detailed explanation. It's clear now.
