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

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 layout > folder; this can lead to crashes when the resource is queried in a > configuration that does not match this qualifier

One of the layouts that I am getting this error is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="fill_parent"
	android:layout_height="fill_parent"
	android:orientation="vertical"
	android:background="@null" >

      <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top|center_horizontal"
            android:adjustViewBounds="true"
            android:contentDescription="@string/hello_world"
            android:src="@drawable/loading_top" />

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|center_horizontal"
            android:adjustViewBounds="true"
            android:contentDescription="@string/hello_world"
            android:src="@drawable/loading_bottom" />

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:contentDescription="@string/hello_world"
            android:background="@color/white"
            android:layout_marginBottom="5dp"
            android:paddingTop="10dp"
            android:paddingBottom="10dp"
            android:src="@drawable/loading_logo" />

        <ImageView
            android:id="@+id/loading"
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center|center_vertical"
            android:layout_marginBottom="0dp"
            android:layout_marginTop="0dp"
            android:contentDescription="@string/hello_world"
            android:scaleType="fitXY"
            android:src="@null" />
    </FrameLayout>
</LinearLayout>

I get the error on the first line of the first LinearLayout.

Does anyone know how to solve this error?

Thank you

UPDATE: Answered my question with what has resolved the problem for me

In my case closing and reopening Android studio solved the problem. Rebuilding the project or clearing the cache didn't help.

You can also try this :

File => Invalidate Caches / Restart => Invalidate and Restart.

In my case it was the use of capital letters in the file name. I left everything in lowercase and it was fixed.

If you devise your layout : layout-sw320dp layout-sw480dp layout-sw600dp layout-sw720dp ....

you should add layout by default like this:

I just did Build > Clean Project

I received this error when moving layout files between Gradle modules. I didn't have to go so far as to invalidate caches as it resolved itself when I restarted Android Studio and cleaned the project. It seems likely to be an IDE bug.

Invalidate Cache / Restart solved my problem.

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.

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      tools:ignore="MissingDefaultResource" <!--this-->
      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

In my case, this issue was caused by Uppercase letter. Wrong chars like "-" can also cause the issue. I changed the name from Activity_disease.xml to activity_disease.xml and the issue fixed.

Nothing worked for me like rebuilding the project or Invalidating the cache. In my case closing and reopening Android studio solved the problem.

Press- 'ctrl+A' --> 'ctrl+x' --> 'ctrl+v') this does not change anything but apparently solves the errors.

I solved this issue by just syncing project with gradle

I had copied the xml files in the folder using Windows Explorer. It seems to have caused an encoding issue. After deleting the files and coping them inside Android Studio, the problem was resolved.

In my case it seems that Google used to expect (or at least accept) different names between different layouts; I had a time_dialog.xml and a time_dialog_landscape.xml. Renaming the latter to time_dialog.xml fixed the problem.

For me the following steps made it work:

1. Cut all the code out of the page (ctrl+A+X for windows)
2. Paste the code back.

I had an issue after copy/pasting code into an XML layout file, but I fixed it by just manually creating the file. Very strange, since the code was exactly the same, but somehow it fixed this issue. I did try restarting and doing the "File => Invalidate Caches / Restart => Invalidate and Restart" fix, but the issue was only fixed by manually recreating the file.

Note that when you are using different versions of layout like (Large/Small/Nornal) then that case you have to same main layout folder. like this way

Similarly to the previous post, I had to rename the resource. I created it initially by copy-pasting an .xml file in the project explorer. Confusingly this had the same name in the explorer but with a land dimmed attribute associated with the layout.

My solution was to go into the file system and manually move the file from the layout-land to layout folder

For me it occured because I had accidentally named the file with a spacebar rather than underline, i.e fragment_item summary.xml rather than fragment_item_summary.xml.

This issue seems to be happening because studio or compiler is not able to find the resource file inside the base layout folder. To solve the problem you might need to create the file into different layout folders. If you are using layout folders v21, v25 etc. folders for designing layouts for different target devices then you also might need to place your resource files there too.

In my case this warning appeared due to "wrong" character (dot) used in value name:

<dimen name="dp.divider.xlarge">24dp</dimen>

Removing dots (right click on a name, then Refactor-Rename in Android Studio) resolved the problem.

Late to the party but My case is different from above.

I just renamed the resource and it started working.

Actually my resource name was ic_menu_black_24dp.xml so it was conflicting with the android's menu resource.

What worked for me is to remove the id attribute

android:id="@+id/[id same as filename]"

from the layout resource.

(1) Delete the original layout.

(2) Add the layout again.

Step-1

Step-2

What solved it for me:

In Android Studio, right-click on the filename in the layout directory, and choose Reformat code, with no special tickbox selected on the next screen.

Not sure what exactly goes on under the hood here, but that worked.

In my case the same error was showing because layout-land file and layout filename was different.

My Case: layout-land -> my_layout_land layout -> my_layout

I solved it by making both filenames the same. Because if you are using layout-land and you have a file in layout-land then you must have a file in layout folder also.

Placing tools:ignore="MissingDefaultResource" in the screen layout description solved it for me.
