I went to the Informal Android Meetup in Mountain View last week to ask for a little help fixing my virtual devices. The nice lady heading it up gave a lot of suggestions, none of which really worked. But we did find that my installation was likely looking in all the wrong places to run my virtual devices. How? I was able to run some from the command line that did not run in the virtual device manager. I copied some information from my system-images folder into where my Android Studio looked for my specific virtual devices. That is way too messy!
Anyhow, the meetup leading lady believes that the best thing for me would be a complete reinstall. I agree. Sure, there will be lots of downloading, since I'll be reinstalling the SDKs and so forth all over again. But it's not like I am not used to that, I've been doing that since Eclipse!
For now, I can run the Android Studio apps directly when I plug in my LG G3 phone. But soon, I'll be cleaning out all the old libraries and the app and reinstalling from scratch (no, I do not just drag the Android Studio app into the trash).
P.S. I found another little bug in Google Assistant. I say, "Ok Google, play Take Five by David Brubeck." I keep getting "Take 5," some little boy band with little high voices that make little pre-teen girls scream for a little while till they find the next little boy band. Ugh. I want the cool Take Five that withstood the test of time, not the Take 5 that had a shelf life of 14 minutes. Click below to hear the REAL Take Five!
