{  
var meetingService = zoomSDK.MeetingService;

```
        if (!string.IsNullOrEmpty(p0))
        {
            meetingService.HandZoomWebUrl(p0);
        }
    }

Unable to find explicit activity class {com.companyname.zoomintegration/com.zipow.videobox.IMActivity}; have you declared this activity in your AndroidManifest.xml?’

Hi @shraddhap, thanks for the post.

Unfortunately our SDKs do not support Xamarin. Please let me know if you are able to reproduce this issue in a native application and we can investigate further.

Thanks!
