Intent to open PDF file in Android N -


i have been trying open pdf file using intent. works fine devices prior adroid n. following code have used

file file = new file(griditems.get(position).getpath());                         intent intent = null;                         if (build.version.sdk_int < 24) {                             intent = new intent(intent.action_view);                             intent.setdataandtype(uri.fromfile(file), "application/pdf");                             intent.setflags(intent.flag_activity_no_history);                         } else {                             intent = new intent();                             intent.setaction(intent.action_view);                             uri pdfuri = fileprovider.geturiforfile(gallerypdfactivity.this, getapplicationcontext()                                     .getpackagename                                             () +                                     ".provider", file);                             intent.putextra(intent.extra_stream, pdfuri);                             intent.setflags(intent.flag_activity_no_history);                             intent.settype("application/pdf");                         }                         try {                             if (intent.resolveactivity(getpackagemanager()) != null)                                 startactivity(intent);                             else                                 apputils.toast("no application found open pdf", gallerypdfactivity.this);                         } catch (exception e) {                             apputils.toast(e.getmessage(), gallerypdfactivity.this);                         }

the file chooser opens , have selected google pdf viewer open app. returns error "cannot display pdf(no file received)" . able open same file in devices prior android n

add flag_grant_read_uri_permission on intent in fileprovider case. otherwise, other app has no access content. see the documentation.
