Describe the bug
To install android virtual devices on linux I have follow this instruction https://docs.nativescript.org/tooling/android-virtual-devices

I have installed the cli tools, downloaded and created an AVD. So when I run ./avdmanager list I get a bunch of devices listed, e.g.

id: 1 or "android-28"
     Name: Android API 28
     Type: Platform
     API level: 28
     Revision: 6

Also I have installed Android Studio and can run a device on the emulator via android-studio -> avdmanager.
But when I run tns device or tns run android I get an error:

Searching for devices...
Cannot find connected devices. Reconnect any connected devices, verify that your system recognizes them, and run this command again.

What can be the issue here?

Expected behavior
Start the emulator
