Hello,

I have incorporated the radListView into my app.  It works great on the geny emulator but when I build the app and install on my phone I get the following error when I load the page with the listview

 

Error: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/widget/RecyclerView;

....

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v7.widget.RecyclerView" on path: DexPathLis

Any ideas?

Hi,

Thanks for writing and for the provided stack trace. It seems rather strange for your app to work on an emulator but not on a real device. Can you share with us some details on the API Level of the device and the API Level of the emulator you are running on. It seems that the AppCompat library's types are missing.

My device reads API Level 25  and the emulator reads API Level 24

Hello,

Thanks for writing back.

Can you please ZIP your project and send it to us for further investigation?
You can do that by opening a new support ticket and attaching your ZIP archive there.

Do you want me to include the node_modules and platforms folder?

[Deyan]

Hello,

Yes - that would be useful. If our system doesn't allow you to upload the ZIP, you may use Dropbox or Google Drive and paste me the link here.

Thanks a lot.

Cool.  I will post this evening.

Hi,

This is a quick follow-up to inform you that we have tried to reproduce the issue on our side without success. Can you please try deleting the `platforms` folder of your app and rebuilding?

Anyway, a ZIP of your whole project would be helpful.

Ticket Submitted.  Thank You for your help.

Hello Randy,

A couple of our customers reported similar issues and they all came down to a missing RecyclerView reference in the Android's platform build.gradle file. Can you take a look at this file, see if there's is a commented RecyclerView reference and uncomment it? This should resolve the issue.
