Description Holger Benl 2014-09-15 09:49:48 UTC
While trying to track down the issue described in Report #22991
I noticed that I couldn't enable gref logging using

adb shell setprop debug.mono.log gref

anymore. I tried this with Xamarin 3.3.47.0 where gref logging
worked and with Xamarin 3.5.58 where gref logging didn't work.

This is a regression in 4.16 which will be fixed in 4.18; see the Known Issues section in the release notes:

http://developer.xamarin.com/releases/android/xamarin.android_4/xamarin.android_4.16/

> This release unfortunately broke debug.mono.log handling;
> the debug.mono.log system property is ignored. Within Xamarin.Android 4.16,
> set the debug.mono.debug system property instead. The debug.mono.log
> system property will be fixed in Xamarin.Android 4.18.

Meaning, within 4.16 you should do:

    adb shell setprop debug.mono.debug gref
