Hi,
If you are using the demo project: You need to click the link then click the Do button.
If you are using your own app, make sure that you have at least the professional license activate.
You need to implement PDFReaderListener.OnOpenURI(String) and make sure that m_reader.PDFPerformAnnot() is called when the annotation is clicked (OnAnnotClicked)..
To handle the action of the link click please check www.androidpdf.mobi/forum/Android-develo...ze-openning-url#6922
