Background service to work even after the app is killed about react-native-background-timer

👍 ... Not sure how tricky this is to implement, but would be a game changer.

@iguatemigarin, maybe it could be implemented with react redux as a state store and listen to native events like onTaskRemoved (android) and applicationWillTerminate (ios). when the app is killed these events should be called, and you could serialize the application state to JSON and write it to disk. When the app boots starts back up, it could Rehydrate the Redux state from JSON and dispatch any events you needed

Just some food for thought :)

Hi, this would be awesome. But some decisions should be made:

1. Should the app "wakeup" the phone or should the callback run in background?
2. After a phone reboot, should the callback run or be forgotten?
3. Should the plugin API expose specific methods for this new feature?

I have an idea of how to do it with Android.

@ocetnik, what do you think?

[EDIT]

After a few tries, I'm not sure if this is possible. Once the app is killed the react native context is lost. I've managed to schedule some calls with Alarm, Intent and BroadcastReceiver. But I can't get back to the original react native context. This means I can schedule some code execution for later, but only native (Java) code, not JS :(

Any thoughts? My Android background is really shallow...
