Null reference exception when adding FreeTextAnnotation

Hello, I'm developing an Android app using Syncfusion.SfPdfViewer.Android.


I found that adding FreeTextAnnotation makes null reference exception.

It worked well before, but not now.


Below is my code that makes null reference exception and I attached sample project.


        private void BtnTextAnnot_Click(object sender, EventArgs e)

        {

            FreeTextAnnotationSettings TextSetting = new FreeTextAnnotationSettings();

            TextSetting.IsFreeTextDialogEnabled = true;

            TextSetting.TextColor = Android.Graphics.Color.Black;

            TextSetting.TextSize = 20;

            Viewer.AnnotationSettings.FreeText = TextSetting;

            Viewer.AnnotationMode = AnnotationMode.FreeText;

           // text frament is shown well, but pressing "OK" make exception

           // ...

        }


Please review and update.

Thank you.
