}

but shows html code, not actual pdf view. putting wrong google drive url? or it's not possible show google drive.

any free web hosting pdf file appreciated.

in addition @derek fung's answer, if drive having login session may need provide session access well.

but if use view url user not propted login there google account.

simply can use this::

 webview.loadurl("https://docs.google.com/viewer?url="+ pdfurl);
