Hi Shirley

Thank you so much. It’s working as my expectation.

I have one more Question.

How pdftron load a document? because if the document size is large so it’s taking long time to load or show. I tried to load large size of xls file, untill loading is not complete its showing blank page. How can we overcome this issue ?

Hi @pawan.verma ,

This takes a long time because the XLS needs to be processed before it’s displayed. Currently it will just display a blank document until the loading tis complete. Would it be an option if there was a progress bar to show while it’s loading?

Here’s some sample code to get that working: In your layout file:

    android:layout_height="60dp" />
 In your activity/fragment:

mPdfViewCtrl.addDocumentLoadListener(new PDFViewCtrl.DocumentLoadListener() {
    public void onDocumentLoaded() {
        ProgressBar progressBar = findViewById(;

Hi Ryan. How did you manage to get over this ? I’m facing the same issue

Hi Ryan,

Are there any plans to support Excel 95 or older files in the near future or at all?
