"very first "context" available is "application". Isn't that what you need?" - OK, I selected the app, what's next? How should I tell to Tasker that this profile should be triggered once this app in foreground (on the phone screen)?
In my Tasker there are only Activity, Services, Invert, and All buttons in the bottom of the App selection (Tasker->NewProfile->Application->here these buttons/options).
When I select 'Activity' for a specific App and then launch the App, the profile is not triggered. Why?
