How do generate Android APKs by build variants?

[transdev]

Greetings everyone! I am new to Bitrise, so I am gradually learning their service. I have a question regarding generating APKs. How can I setup my builds to generate APKs based on build variants? I have posted my YAML below. And my assumptions on changes. Can anyone help with this? Thanks in advanced

Here is our premise

1. We have 3 environments i.e. debug, stage, release
2. We have 2 product flavors i.e. freemium, subscription

Hi @transdev,

Please see this #how-to : How to build different flavors of an Android project

If you’d have any questions just let us know!

@viktorbenei

I think I may have got this to work. If I understand the tutorial correctly, ALL flavors will build if I do not specify any flavor specifically but instead only define a type. Like this correct?

[viktorbenei]

Indeed, that’s correct
