If your Android is an older one, so up to Android 10, there is a good chance to import it into your Krita, but the newer Android and the cruder the manufacturers OS-Plug additionally put over it the smaller the chance.
Way one is the same as on every OS, open Krita’s resource folder out of Krita via Settings > Manage Resources... where you have to click the button Open Resource Folder which will then open the resource folder (theoretically), if that works for you, you have nearly won! Now you have to enter the folder color-schemes and copy the color scheme files you want to import into that folder.
Please try that first with the Android file manager, if that won’t work, you can go and download the free of charge file manager Total Commander (from Ch. Ghisler!) from the Play Store, that is a two pane file manager where you can put the files to copy in one pane and open the color-schemes-folder in the other, if you are lucky, then Android allows copying the files with Total Commander.
And there is a second way to reach your resource folder if it does not work directly out of Krita:
Alternatively, you can browse with your file manager/Total Commander to the path/folder that is shown to you in Krita, in the tab
Resourcesthat you will find via the menuSettings>Configure Krita>General, it is the tab at the right end.
Here you see where to find this as example on Windows, I’ve highlighted the path, you need to browse to the path that is shown in there in your Krita:
If you are able to reach that folder you have to do the same what I already wrote above, copy the unpacked color scheme files into the folder color-schemes.
Once the files are copied into the folder color-schemes, you must start/restart Krita two times and should find them then under Settings > Themes.
