The layout in layout has no declaration in the base layout folder [error]

Question

After migrating to Android Studio 3.2, API 28, I am getting the following error on my app\'s layout:

The layout in layout has no declaration in the base lay

Answer 1

In my case i resolved that with this:

the Android say me this id-error:MissingDefaultResource as documentation say:

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.)

 
      android:layout_width="match_parent"
      android:layout_height="match_parent">

But this is the easy solution, 'cause you make missing the resourse in Android.

I resolve this with file system option. If Android tell you about missing resourse meaning some thing is missing and you should replenish that.

you should be go to \app\src\main\res

maybe: right click in file's missing folder, show in Exporer,and go back to \app\src\main\res

You should be find

/layout

/layout-normal

/layout-large

/some more folders

You should be find where do the files is missing. In my case that's missing in /layout
