Where do the 'Build Variants' in AppCenter come from and is there extra setup required for each one?

Question

I am struggling to get my AppCenter to build my Android app, so I wanted to try and understand a few things to see if I can debug the issue. Where do the different build variants come from and what significance are they when choosing, as in what do I need to make sure is set in my gradel files etc in order for them to run correctly? In my case I have the following available. Having a look in my app.iml file, I can see that the 'SELECTED_BUILD_VARIANT' is set to devMinSdkKernelDebug however I do not see this in any of the build variant listed on AppCenter, so I am wondering if this is the reason the build is failing? The error I am getting on AppCenter is that 'assembleDevMinSdkDebug' not found in project ':app'. Whereas the ASSEMBLE_TASK_NAME is set to assembleDevMinSdkDevKernalDebug in the iml file? I have tried changing these to match but still not working, but thinking I may need to do some extra set up elsewhere? Please if anyone has any ideas I would like to hear them as I am totally stumped!

Answer 1

From the AppCenter document: The available build variants will populate from the Build Types and Product Flavors specified in the build.gradle file. Select which build variant should be built. Build variant So I think you should check your build.gradle file instead of the app.iml file.
