Question

I am working on an Android sms application.The following code I used to send sms.

public void sendSms(final String phoneNumber, final String message){


    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED),0);

   //--- When the SMS has been sent --

    sendBroadcastReceiver=new BroadcastReceiver() {


        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            switch (getResultCode()) {

                case Activity.RESULT_OK:

                    Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();

                    ContentValues values = new ContentValues();
                    values.put("address", phoneNumber);
                    values.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/sent"), values);


                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();

                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();

                    ContentValues values1 = new ContentValues();


                    values1.put("address", phoneNumber);
                    values1.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/queued"), values1);

                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:

                    Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:

                    Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                    break;

                default:
                    break;
            }

            context.unregisterReceiver(this);
        }
    };

    SmsManager sms = SmsManager.getDefault();

        registerReceiver(sendBroadcastReceiver , new IntentFilter(SENT));
        sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);

}

It is working fine when I keep the screen until sms sent. It will write that sms to content/sms/sent or queued depends on sent report.But if i press back button while sending sms .it will send the sms but do not write to content/sms/sent or queued also won,t unregister broadcast too.

Please help me to solve my issue.

I had solved my problem by using service. Using startservice() and stopservice() I can manage registeration.Thanks for the suggestions friends.
