It's because the ListView component has recyclerview and cardview libraries built-in.

              description = "<p>This is a visible component that displays a list of text and image elements.</p>" +
                  " <p>Simple lists of strings may be set using the ElementsFromString property." +
                  " More complex lists of elements containing multiple strings and/or images can be created using " +
                  "the ListData and ListViewLayout properties. </p>",
              category = ComponentCategory.USERINTERFACE,
              nonVisible = false,
              iconName = "images/listView.png")
          @SimpleObject
          @UsesLibraries({"recyclerview.jar", "recyclerview.aar", "cardview.jar", "cardview.aar", "dynamicanimation.jar"})
          @UsesPermissions(permissionNames = "android.permission.INTERNET," +
                  "android.permission.READ_EXTERNAL_STORAGE")
          public final class ListView extends AndroidViewComponent {
          
            private static final String LOG_TAG = "ListView";
          
            private EditText txtSearchBox;
            protected final ComponentContainer container;
            private final LinearLayout linearLayout;
          
            private RecyclerView recyclerView;
            private ListAdapterWithRecyclerView listAdapterWithRecyclerView;

any solution for this ?

As you are encountering issues with missing resources, it will not be feasible to include them with the extension. I kindly suggest that you remove the recyclerview jar and rely on the in-built libraries.

suposed user used my extension then he cant use ListViewComponent i m right ?

If you remove the recyclerview jar from your aix and rely on the in-built library with the ListView component, users will be able to use the ListView component. For now, this would be the most suitable option for you.
