Web page not available error

[rajeshkumarmanickam]

I am getting below error when I run the sample application

the web page at file:///android_asset/pdfjs/web/viewer.html?file=file:///data/data/PdfViewerSample.Android/files/xlsdemo2.pdf might be temporarily down or it may have moved permanently to a new web address

I haven't changed anything, Downloaded PdfViewerSample solution and running.
Do I need to change anything?
