OnDestroy被称为WearableListenerService

Question

I am implementing an service inherited from wearablelistenerservice.

Its weird that the onDestroy method being called with the service is still running. What should I do to avoid the ondestroy method being called?

thanks.

Answer 1

Are you deferring some work to the background thread after receiving a callback in WearableListenerService ? If yes, as soon as you leave the callback method scope, the service is a fair game and will be destroyed as soon as system decides so. The only guarantee (sort of) you are getting in WearableListenerService is that it will be kept alive in the scope of the callback method (unless there is a very strong memory pressure). If you need to do some background work, you start an IntentService from the WearableListenerService . However, it might be not necessary. WearableListenerService callback is already on a background thread, so you can do all the work you want. Just don't leave the method scope (no waiting for callbacks or launching AsynTask s; stick to blocking calls).
