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")

          @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.

হেলো রিয়াদ, সমস্যা ধরতে ডিভাইস লগস চেক করেন এবং বুঝতে না পারলে এখানে পেস্ট করেন।

I'd recommend following the text tutorial that's provided, as said before.

It contains all you need to know for using logcat and debugging your apps with it.
