Android production build `MissingDefaultResource` lint error.

When building Android app for production build I get this lint error. Its because generator builds only folders drawable-land-xxxx and drawable-port-xxx. There should be build also default drawable-xxxx folders I think.

Temporary solution is suppress this lint error adding this code to android/app/build.gradle

application {
....
 lintOptions{
   disable 'MissingDefaultResource'
 }
}

MissingDefaultResource

Summary: Missing Default

Priority: 6 / 10 Severity: Fatal Category: Correctness

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.)

That can be the solution.

Here’s what the doc say.

Providing the best device compatibility with resources … Likewise, if you provide different layout resources based on the screen orientation, you should pick one orientation as your default. For example, instead of providing layout resources in layout-land/ for landscape and layout-port/ for portrait, leave one as the default, such as layout/ for landscape and layout-port/ for portrait.

since I upgraded Android Studio I have the same problem 😦 To solve also I have inserted in build.gradle:

lintOptions{
    disable 'MissingDefaultResource'
}

Is this sufficient, or will there be problems with the App? Thanks!
