Question

So I am fairly new to android programming. I have a database and I want to be able to take the information from the database stored on the android device, store it in a .csv file, attach it to an email, and send it to the receiver. This is however my first time working with a .csv file and I want to make sure I am doing it right.

I looked at this page: Convert database .db file into .csv

But I am not sure the correct way to implement this using my current code, or even if this is what I am looking for.

I also tried using a bit of: OpenCSV

and noticed a section about dumping SQL into a .csv, would this be the best way to implement it? Any and all help and advice would be appreciated, thank you for your time!

Answer 1

If you are not too commited to attaching a csv file, it is really easy to just dump a big string into the body of an email, and send it to someone. You don’t have the issue of writing a local file and attaching it.

When sending an email you can just add:

emailIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

where emailBody is a big string that has your data in it.

At least this might be an interim solution?

Here is a little code that can send an email with a big string of text in it.

              String emailSubject = " Sent from my Android";
        String emailBody = "";


        // create a big String that has your data in it called emailBody

        Intent i = new Intent(Intent.ACTION_SEND);
        i.setType("text/plain");

                           // send it to yourself for testing
        // i.putExtra(Intent.EXTRA_EMAIL , new
        // String[]{"[e-mail]"});

        i.putExtra(Intent.EXTRA_SUBJECT, emailSubject);
        i.putExtra(Intent.EXTRA_TEXT, emailBody);

        try {
            startActivity(Intent.createChooser(i, "Send mail..."));
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(HistoryActivity.this,
                    "There are no email clients installed.",
                    Toast.LENGTH_SHORT).show();
        }
