Answer 1

आप की तरह यूआरआई का उपयोग कर संपत्ति निर्देशिका में पीडीएफ फाइल myfile.pdf को संदर्भित किया जाना चाहिए:

Uri uri=Uri.parse("file:///android_asset/myfile.pdf"); 

Answer 2

i've done for send any file from SD card with mail attachment.. 

Intent sendEmail= new Intent(Intent.ACTION_SEND); 
     sendEmail.setType("rar/image"); 
     sendEmail.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new   
     File("/mnt/sdcard/download/abc.rar"))); 
     startActivity(Intent.createChooser(sendEmail, "Email:"));
