Firewall temporary allowance notification is not displayed

[vozersky]

Reproduced on Samsung s7

Could be a foreground detection issue.

Here's what we should do

In order to detect if the app is in foreground or not, we should be using the UsageStatsManager: https://developer.android.com/reference/android/app/usage/UsageStatsManager.html

The only question is when should we ask for the necessary permissions. I suggest doing it every time user decides to block network access for some app (or a list of apps via the batch action).

More info

queryEvents can be slow, we have to test it.

Looks like it became a common issue for all devices with Android 7.
Firewall temporary allowance notification doesn't work anymore.

[nkartyshov]

This problem is not solve now. Android 7 restrict access to folder /proc for other processes, but solve this problem help use UsageStatsManager.

Information about UsageStatsManager: https://developer.android.com/reference/android/app/usage/UsageStatsManager.html.

Delayed to v3.0 as this UsageStatsManager integration will take quite some time, and I'd like v2.9 to be released as soon as possible.

Great to see you're working on fixing this issue. The notification feature was great, hope it'll be back in the future. Good luck.
