Android Question Can't show toast message with app in background (api 34)

I test this on a device with api 34

Have you set the targetSdkVersion to 34?

Yep, I have. I've done several tests, and for me it seems to be a rock-solid connection between being able to show toasts from the background and having the notification permission.

Are you getting different results?

Follow-up: At another place in my test app I had a notification. Just to test that I hadn't made a mistake somehow, I removed that notification code.

When I ran the app again, no toast did display, just as before. But when I went into the app settings to enable the notification permissions it said that the app doesn't use notifications, so I couldn't enable it. Bottom line is that I can't make the toasts display now.

Weird stuff. I feel like this should be documented in the Android docs but I was only able to find these two pages, which doesn't mention anything about it:
- https://developer.android.com/guide/topics/ui/notifiers/toasts
- https://developer.android.com/reference/android/widget/Toast

Both pages make me feel like Google is trying to steer us away from toasts.

"Note that Snackbars are preferred for brief messages while the app is in the foreground.

Note that toasts being sent from the background are rate limited, so avoid sending such toasts in quick succession."

Really Google, Snackbars what next???

I haven't tried it yet, however you shouldn't set targetSdkVersion to 34 for now.

Yeah, I know. I just tried it as I was setting up a bunch of devices and the option to set up a 34 device was there.
