I'm getting the following intermittent exception in the Android version of my application.



java.lang.ClassCastException: au.com.bluetigertech.docsontap.PdfViewerActivity@413a12c0 must implement OutlineDialogFragmentListener

My PdfViewerActivity class declaration looks like:

public class PdfViewerActivity extends BaseActivity implements
		PDFViewCtrl.RenderingListener, PDFViewCtrl.PageChangeListener,
        AnnotationDialogFragment.AnnotationDialogFragmentListener,
        BookmarksDialogFragmentListener, OutlineDialogFragment.OutlineDialogFragmentListener,
        pdftron.PDF.Controls.ThumbnailSlider.ThumbnailSliderListener,
        ThumbnailsViewFragment.ThumbnailsViewFragmentListener,
        ToolManager.PreToolManagerListener, SearchView.OnQueryTextListener,
        PDFViewCtrl.TextSearchListener, ToggleToolbarsListener {




Can you help me out with why I would be receiving this exception?



Thanks,

Could you please post here, or email to support, your PdfViewerActivity.java file.

Or better yet, send us a compilable/runnable project that we can run.

Hi Ryan - I’ve attached a copy of my PdfViewerActivity.java file.

Thanks,

David

We don’t see anything wrong with that file, though it looks like at least your tools library is quite old.

I would recomend updating PDFNet and the Tools code.

Otherwise we need compilable/runnable project to diagnose further.
