Create a File object of your asset folder file and attach this object to your email Intent.
And as mentioned in your Question runtime error file not found exception this may be cause the URL "file:///android_asset/" doesn't point to a particular directory, it is only used by WebView to address assets. Pulled that from
you can open this as an input stream and covert this InputStream
to File
in = new BufferedReader(new InputStreamReader(activity.getAssets().open(myfile.pdf)));
Send this file object in email as follow.
Intent intent = new Intent(Intent.ACTION_SEND ,Uri.parse("mailto:"));
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "Card Set ");
intent.putExtra(Intent.EXTRA_TEXT, "");
intent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(file));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
activity.startActivity(intent);
Where Intent.ACTION_SEND
used to send Email , Intent.EXTRA_STREAM
for the attachments with email. you can have multiple Intent.EXTRA_STREAM
in single intent to refer multiple attachments with intent.setAction(Intent.ACTION_SEND_MULTIPLE);
.
intent.setType(String mimeType)
input param is represent the MIME type data that you want to get in return from firing intent(here intent instance).where setype can be
