Android Question Recognize Third Party App Open

Is there a way to recognize when a third-party app opens on screen?

I would like to recognize on Android when Skype has an incoming call. Skype will pop up a full page screen announcing the incoming call.

If the call is missed Skype posts a notification of the missed call. I use Erel's NotificationListener to detect this missed call notification and I flash some Wi-Fi connected light bulbs. The problem is this is a "missed call notification", so the other party has already hung up. Skype currently does not have an "incoming call notification".

I would hope that there is something like the NotificationListener that I could use to detect when Skype opens the page announcing an incoming call. I would then use this to flash the light bulbs.

Is it possible to detect a third-party app opening? Can anyone point me in the right direction?

Thanks,
Barry.

You can use my accessibility services library. If I recall correctly I exposed a method or event to get the current activity

Thanks. Polling for the currently running activity is definitely a possibility. Polling every 15 seconds or so 24 hours a day doesn't sound nice, but it's on an older phone (API 23), the phone is dedicated to this one task, and it's constantly plugged in to the charger – so I guess the usual warnings about polling don't matter.

I will have to play around and see if the Skype screen that pops up has a unique activity name. Skype pulls all sorts of tricks so it may be the same activity as the normal Skype calling page just showing a different view.

Barry.
