Merge multiple PDF page from Internet

Hello,

I'm striving to get PDFViewer for Android to download multiple PDF page from remote host and merge them into a unique PDF file each time a single PDF page is downloaded.

Can someone help please?




Thanks

another way is:
derive Document class, and manage multi PDF like 1 PDF Document.
just like SuperDoc class, which exists in last version.

Great.

But cannot understand how to update PdfView after each single pdf page has been downloaded and store into sdcard without ruining the user experience, i.e. do not change zoom of current pdf page


Thanks
