Hi all

To select this Stack you just have to open your app on [bitrise.io](https://www.bitrise.io),
go to the Workflow tab (Workflow Editor), and on the Stack tab select the Android & Docker, on Ubuntu 20.04 option and your next build will start on the Linux Android stack.
- Note: you can now select separate stacks for separate workflows!
