How do the retrieve the date of the mms from content://mms.

Question

I did get the information on how to retrieve the text and the image for the mms sent from this link: How to Read MMS Data in Android?.

But I am not sure how to retrieve the date for the mms that was sent.

I know I have to look into content://mms and not in content://mms/part.

This is the Mothod to retrieve the mms text:

private String getMmsText(String id) {
        Uri partURI = Uri.parse("content://mms/part/" + id);
        InputStream is = null;
        StringBuilder sb = new StringBuilder();
        try {
            is = getContentResolver().openInputStream(partURI);
            if (is != null) {
                InputStreamReader isr = new InputStreamReader(is, "UTF-8");
                BufferedReader reader = new BufferedReader(isr);
                String temp = reader.readLine();
                while (temp != null) {
                    sb.append(temp);
                    temp = reader.readLine();
                }
            }
        } catch (IOException e) {
        } finally {
            if (is != null) {
                try {
                    is.close();
                } catch (IOException e) {
                }
            }
        }
        return sb.toString();
    }

and then, in the onCreate method, I use this code to get the info:

Cursor cursor = getContentResolver().query(uri, null, selectionPart,
                null, null);
        if (cursor.moveToFirst()) {
            do {
                String partId = cursor.getString(cursor.getColumnIndex("_id"));
                String type = cursor.getString(cursor.getColumnIndex("ct"));
                if ("text/plain".equals(type)) {
                    String data = cursor.getString(cursor
                            .getColumnIndex("_data"));

                    if (data != null) {
                        // implementation of this method above
                        body = getMmsText(partId);
                    } else {
                        body = cursor.getString(cursor.getColumnIndex("text"));
                    }
                }
            } while (cursor.moveToNext());
        }

        try {


            main.setText(body);
            img.setImageBitmap(bitmap);
        } catch (Exception e) {

            e.printStackTrace();
        }

I just want to know where can I make changes to get the date value.

Some info will be really helpful.

I'm not overly familiar with MMS's, but I'd imagine something like this would at least get you started

Cursor cursor = activity.getContentResolver().query(Uri.parse("content://mms"),null,null,null,date DESC);
count = cursor.getCount();
if (count > 0) 
{
    cursor.moveToFirst();
    long timestamp = cursor.getLong(2);
    Date date = new Date(timestamp);
    String subject = cursor.getString(3);
}

It's completely untested of course, but should point you in the right direction. Hope this helps!

Edit After doing a bit of reading, there used to be (possibly still is) a "bug" with the timestamp in MMS messages, when retrieving the data. If you end up with a silly value (like the epoch), you'll have to * 1000 before using it. Just an aside :) I.e.:

long timestamp = (cursor.getLong(2) * 1000);
