Comment 1 Alex Rainman 2016-09-19 13:40:45 UTC
I was able to fix this. I downgraded my Xamarin.Android to version 6.1.2. It seems the problem is latest Xamarin.Android version.

Comment 3 jellis 2016-10-28 13:33:14 UTC
confirmed seeing the same bug running Xamarin Studio on Macbook with latest stable Xamarin Android - on Debug build with Shared runtime enabled.  Turning off shared runtime resolves for now.  I believe it is the same bug as this one: https://bugzilla.xamarin.com/show_bug.cgi?id=44439
Comment 4 Jonathan Pryor 2016-11-04 18:47:25 UTC
This looks like a DUPE of Bug #44633:

> No original dex files found for dex location /data/app/com.slbdev.LoadChart.Droid-1/base.apk
