Android Question Opening app from notification crashes the app

[Facilauto Juan]

Hello there!

I have an app that has activity a and activity b.
The app has a server that puts push notifications every now and then.
If I click in the notification, I want to show activity b.
But activity B uses a global variable initialized in activity a.

Ok, now:
I start the application from activity a.
I receive a notification.
I click in the notificaton and it shows activity b. And...
Error. It says that the global variable initializated in activity a isn't initializated.

It's like the notification resets the app. Could it be that what's happening here?

Thanks for your answers and your time.

The process was killed and then recreated when you pressed on the notification. Activity a was not created as the notification started activity b.

You should move the relevant variables to a module and then initialize it if needed.

I see...

Is there a way to open an activity from a push notification click without resseting the application?

The app is not reset by default. After a while the OS kills background processes.
