I've been trying to look up solution but I just can't seem to find one that suits my need. It could be that I'm not using the correct keyword, so I'm gonna try to explain it the best I can.
Simply saying, I'm building an Android application. The application need to detect some other activities on the phone and show some message.
For example:
User launch MyApplication.
User received some notification from another app. (a phone call, text message, email, whatever)
MyApplication shows a message via toast or dialog, saying that "you just received an notification from another app"
I'm not entirely sure what function I should be looking for here, any help is appreciated.
Thanks!
You will want to look at NotificationListenerService, this will let you receive calls from the system when new notifications are posted or removed, or their ranking changed.
Once you receive a callback from the NotificationListenerService
, you will want to create a Toast.
Take a look at this tutorial should help you get started.
