android-app:// What's this and is awstats able to handle it ?

[visualperception]

I have found a few of these in my log files:

"android-app://com.google.android.googlequicksearchbox" "Mozilla/5.0 (Linux; Android 4.4.2; TegraNote-P1640 Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.98 Safari/537.36"

so I created an entry in my search_engines.pm file to catch them. However, it does not find them and I have nothing in google catchall and nothing in other refers for them. So I don't know if or where they are being counted. They are not fetching robots.txt so they will not be identified as a robot either.

is awstats able to handle a referer starting with "android-app://" ?

Thanks

I found where they are being counted:

In unknown origin at below external visitors so referer of: "android-app://com.google.android.googlequicksearchbox" doesn't seem be recognised as valid referer.
