android - How can i open pdf from sdcard i can from asset folder -

i using pdf viewer library , able show pdf asset folder while trying sdcard showing progrss bar long time.

i using below code showing asset

    assetmanager assetmanager = getassets();     inputstream in = null;     outputstream out = null;     file file = new file(getfilesdir(), "sample.pdf");     try {         in = assetmanager.open("sample.pdf");         out = openfileoutput(file.getname(), context.mode_world_readable);          copyfile(in, out);         in.close();         in = null;         out.flush();         out.close();         out = null;     } catch (exception e) {         log.e("tag", e.getmessage());     }      intent intent = new intent(this, mypdfvieweractivity.class);     intent.putextra(pdfvieweractivity.extra_pdffilename, getfilesdir() + "/sample.pdf");     startactivity(intent);  }  private void copyfile(inputstream in, outputstream out) throws ioexception {     byte[] buffer = new byte[1024];     int read;     while ((read = in.read(buffer)) != -1) {         out.write(buffer, 0, read);     } }} 

and using below code showing sdcard

    intent intent = new intent(this, mypdfvieweractivity.class);     intent.putextra(pdfvieweractivity.extra_pdffilename,             "mnt/sdcard/sample.pdf");  /*  intent.putextra(pdfvieweractivity.extra_pdffilename,             "assets/sample.pdf");*/      startactivity(intent); } 

you can try access pdf file sdcard this:

file mypdffile = new file(environment.getexternalstoragedirectory(),"sample.pdf"); string path = mypdffile.getabsolutepath();  //open pdf method             openpdffilewithfilepath(path);  protected void openpdffilewithfilepath(string path) { // todo auto-generated method stub  try {         final intent intent = new intent(this, mypdfvieweractivity.class);         intent.putextra(pdfvieweractivity.extra_pdffilename,path);         startactivity(intent);     } catch (exception e) {         e.printstacktrace();     } } 

i hope helps.
