Answer 1

did just make a sample project and tested it..

Add to your Manifest :

<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.WRITE_SMS"/>

And try the code from SO

private void deleteDrafts() {
    /*
     * This will delete all drafts from Messaging App.
     */
    try {
        Uri uriSms = Uri.parse("content://sms/draft");
        Cursor c = getContentResolver().query(uriSms,
                new String[] { "_id", }, null, null, null);

        if (c != null && c.moveToFirst()) {
            do {
                long id = c.getLong(0);
                Log.d("Delete Draft ID", "" + id);
                getContentResolver().delete(
                        Uri.parse("content://sms/" + id), null, null);
            } while (c.moveToNext());
        }
    } catch (Exception e) {
        Log.d("error", "" + e.getMessage());
    }
}

Hope it helps :)

Try this one:

Uri deleteUri = Uri.parse("content://sms");
getContentResolver().delete(deleteUri, "type=?", new String[] {String.valueOf(3)});
