B4A AVD Manager previously worked 100% perfect on all the AVDs that I created, that includes those creating using fine on Platform 28, also I've been using V3.30 since last year. All I know is that a few weeks ago everything was working fine, and now it's not. The last time I used the emulator was about 6 weeks ago. I'm going to presume that it has something to do with an Android SDK update, as that wouldn't be the first time updates has messed something up.
Now I'm getting this every time I start the B4A AVD manager.
I've not spent that much time on this issue as I have plenty of devices to create and test on, plus I'm currently working on a clients warehouse application.
It would be nice to get the AVDs working again at some point.
