Open PDF on a specified section was created by robaba

Hi,
from your Android sdk i know how to open a pdf on a specified page i.e. by suppling in the Android 's intent a page.
Is there another way to open a pdf on a certain "section"? For example by setting a TOC's element? How can i achieve that?

The demo project expects only a page index.

You can implement this by for example, saving the page index that corresponds to the TOC element somewhere and pass that to the intent. Or you can after openning the document scan the TOC and search for that TOC element and get the page to navigate to.

By reading the docs section and the knowledge base i can't find an example of that.
Can you provide a sample of "scan the TOC and search for that TOC element and get the page to navigate to", please?

Something like:

Code:

private void scanOutlines(Document.Outline parent) {
        for (Document.Outline root = parent; root != null; root = root.GetNext()) {
            //some check here
            if(root.GetTitle().equals("xxx")) {
                m_view.PDFGotoPage(root.GetDest());
                break;
            }
            if(root.GetChild() != null)
                scanOutlines(root.GetChild());
        }
    }

And call it like:

Code:

if(m_doc.GetOutlines() != null)
        scanOutlines(m_doc.GetOutlines());
