Generate and print a PDF with specific size in Android -

-

i'm working in android application, , want generate , print pdf. i'm having trouble. need generate pdf 80mm of width, , height may vary.

i'm trying this:

public class pdfgenerator implements runnable {     private context ctx;     private view view;     private intent mshareintent;     private outputstream os;      public pdfgenerator(context ctx, view view) {         this.ctx = ctx;         this.view = view;         makeandsharepdf();     }      public void makeandsharepdf() {         new thread(this).start();     }      @targetapi(build.version_codes.kitkat)     public void run() {         printattributes printattrs = new printattributes.builder().                 setcolormode(printattributes.color_mode_monochrome).                 setmediasize(printattributes.mediasize.iso_c7).                 setresolution(new printattributes.resolution("zooey", ctx.print_service, 500, 500)).                 setminmargins(printattributes.margins.no_margins).                 build();          pdfdocument document = new printedpdfdocument(ctx, printattrs);         pdfdocument.pageinfo pageinfo = new  pdfdocument.pageinfo.builder(view.getwidth(), view.getheight(), 1).create();         pdfdocument.page page = document.startpage(pageinfo);         view.draw(page.getcanvas());         document.finishpage(page);          try {             file pdfdirpath = new file(ctx.getfilesdir(), "pdfs");             pdfdirpath.mkdirs();             file file = new file(pdfdirpath, "danfe.pdf");             uri contenturi = fileprovider.geturiforfile(ctx, "br.com.rdscodes.nfcelular", file);             os = new fileoutputstream(file);             document.writeto(os);             document.close();             os.close();             sharedocument(contenturi);         } catch (ioexception e) {             throw new runtimeexception("error generating file", e);         }     }      private void sharedocument(uri uri) {         mshareintent = new intent();         mshareintent.setaction(intent.action_send);         mshareintent.settype("application/pdf");         mshareintent.putextra(intent.extra_subject, "nfc-e");         mshareintent.putextra(intent.extra_stream, uri);         ctx.startactivity(mshareintent);     } }

this code generates pdf, letter size.

i saw in android developers media size documentation "iso_c7" media size size want, can change "printattrs" , nothing changes on final result of pdf.

are there better ways generate , print pdf? how can generate pdf 80mm of width?

this part of app made old employee.

thanks.

just don't break head on it, did, check out bug report: https://code.google.com/p/android/issues/detail?id=180405

considering bug report, i'd it's problem android printing interface , can't set defaults using printattributes, @ least not until android n.

if find/found workaround, please let me know :)

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
