I got the following issue.
I have my app written and tested on my personal android device, that worked fine. Now I want to test different android versions and created some AVDs and wanted to run the app. But it does not work. adb devices shows the ADV correctly. tns device does only show my hardware device.
Environment: CLI: 6.0.3 Cross-platform modules: 3.0.4 Android Runtime: 6.0.1 iOS Runtime: 6.0.1 OS: Windows 10 1903
See the output of tns device --log trace here: Github issue
