Current list of installed sdk packages on Android Docker Ubuntu 16.04 - LTS Stack doesn’t include the latest android versions: 28 and 29. Because of that it is not possible to create emulator with latest API.
Install missing packages also is not the option because it seems that the space on this environment is very limited.
