Android Studio says "androidx.drawerlayout.widget.DrawerLayout" was not found in the project or libraries, even though I already add it in the gradle

Question

Also below is the code text from the same snippet that has been attached.

<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

It doesn't work too.....The error only shows on this project, but when I create new project, it seems fine — Sam Sing, Feb 02 '22 at 02:15
I'm currently using AppCompat......Relative Layout...does this thing matter on my problem?? — Sam Sing, Feb 02 '22 at 02:16
did you check ending tag of `drawer layout` it must close and this should be a root layout — Vishal Beep, Feb 02 '22 at 04:31

Try doing any of these methods:

Close your android project by going to File -> Close Project. And then import it again
If above option doesn't works for you then Go to File -> Invalidate Caches/Restart

If neither of them work the remove the dependency and add it again and tell me the build output when gradle sync finishes

It may possible that your studio cache is corrupted;

So

close your all project first; then
open your studio path in your C:\ Drive; for eg. it should like C:\Users\hp(Your_User_Name)\.AndroidStudio4.0\system\caches... Delete this caches folder.

Now start your project again, issue will gone now.

Hope this may help to someone.
