        Cursor c = context.getContentResolver().query(uriSms, new String[]{"_id"}, null, null, null);

        if (c != null && c.moveToFirst()) {
            do {
                long id = c.getLong(0);

                if (id == messageId) {
                    context.getContentResolver().delete(
                            Uri.parse("content://sms/" + id), null, null);
                    Log.e("Message:", "Message is Deleted successfully");
                }

            } while (c.moveToNext());
        }

        if (c != null) {
            c.close();
        }
    } catch (Exception e) {
