Detect app activity (Display info not changed)

Hi all ! Could anyone suggest please … is it possible in Ionic2 detect what happend in app in current time ? Is it possible to analize when your app is stuck and when nothing changed on display …

Can you explain which use case you want to cover with this?

Sujan12, good day ! For example understand when app doesn’t do anything (not inserting data to the db,not downloading something from http), just launched …

If some code doesn’t work and do what it should normally you get an error you can handle.

Sujan12, yes some code should work and I have event something like “Done” … But sometimes my app “Freezes” in the middle work and I do not have any errors …
