Android Question Custom Dialog or Toast or Message be called by service

[youjunjer]

I write an app for fraud detection now. In this app, I need a message box can be called from service. And this message can be clicked to show another detail content (such as call main activity to show some information).
I have tried for the 3 options:
1. Toast: can be called by service, but cannot click.
2. Msgbox: cannot be called by service
3. Dialog: cannot be called by service
Any other suggests?

use notification, can be clicked and you can set a value that can be retrieved after you call an activity
