This folder configuration ('v26') is unnecessary; 'minSdkVersion' is 26. Merge all the resources in this folder into 'mipmap-anydpi'

Question

I'm getting this message in the Code Analysis after setting my Min SDK to 26.

This folder configuration ('v26') is unnecessary; 'minSdkVersion' is 26. Merge all the resources in this folder into 'mipmap-anydpi'.

However, I don't know exactly what to do with this?

I have tried to reformat the existing folder into 'mipmap-anydpi' and then it gives me 20 error messages saying the icon is defined as both Bitmap and XML in every mipmap folder (hdpi, xhdpi etc.

There's also a button I can click to let Android studio handle it. The button says "Merge resources from -anydpi-v26 into mipmap-anydpi". However, when I click it, it just creates an empty XML file at the bottom. And that file complains that it doesn't have a root tag (no wonder, because it's empty). I also can't transfer the XML tags from the 26 folder into this folder because then I get another error message saying I have multiple roots, or that it can't find the XML schema.

How am I supposed to address this?

You also need to remove all the ic_launcher.png files from your mipmap-mdpi/mipmap-hdpi etc. Then Android v26 and beyond would take the only launcher icon you have in mipmap-anydpi.

Also, as referenced in the comments to this SO answer you can even name that folder as just mipmap.
