Explanation for issues of type “MissingDefaultResource”:  
If a resource is only defined in folders with qualifiers like -land or -en,  
and there is no default declaration in the base folder (layout or values  
etc), then the app will crash if that resource is accessed on a device  
where the device is in a configuration missing the given qualifier.

As a special case, drawables do not have to be specified in the base  
folder; if there is a match in a density folder (such as drawable-mdpi)  
that image will be used and scaled. Note however that if you only specify  
a drawable in a folder like drawable-en-hdpi, the app will crash in  
non-English locales.

There may be scenarios where you have a resource, such as a -fr drawable,  
which is only referenced from some other resource with the same qualifiers  
(such as a -fr style), which itself has safe fallbacks. However, this still  
makes it possible for somebody to accidentally reference the drawable and  
crash, so it is safer to create a default dummy fallback in the base  
folder. Alternatively, you can suppress the issue by adding  
tools:ignore=“MissingDefaultResource” on the element.

(This scenario frequently happens with string translations, where you might  
delete code and the corresponding resources, but forget to delete a  
translation. There is a dedicated issue id for that scenario, with the id  
ExtraTranslation.)

🤔

I think this is case of the resources not being found/configured correctly.

Could you try to see if they are in the config.xml?
