Send SMS in Android

This blog will show you how to send SMS and get delivery report.

Step 1:  Declare these BroadcastReceivers. 

BroadcastReceiver sendBroadcastReceiver = new sentReceiver();
    BroadcastReceiver deliveryBroadcastReciever = new deliverReceiver();;

 Step2: Include these inside your button click or anywhere:

 send_sms.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub 

                         sendSMS("phone_no", "sms_content");
                        finish();

            }
        });

Step 3: Implement the sendSMS method

 
private void sendSMS(String phoneNumber, 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);

        registerReceiver(sendBroadcastReceiver, new IntentFilter(SENT));

        registerReceiver(deliveryBroadcastReciever, new IntentFilter(DELIVERED));
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);


    } 

Step4:   Declare the deliverReceiver class

class deliverReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), sms_delivered,
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(getBaseContext(), sms_not_delivered,
                        Toast.LENGTH_SHORT).show();
                break;
            }

        }
    }

Step 5: The same way declare the sentReceiver class.

    class sentReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), sms_sent, Toast.LENGTH_SHORT)
                        .show();
                startActivity(new Intent(SendSMS.this, ChooseOption.class));
                overridePendingTransition(R.anim.animation, R.anim.animation2);
                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();
                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;
            }

        }
    }

Step 6: The important thing is to destory the receivers, while moving the next activity. 

@Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();

        try {
            unregisterReceiver(sendBroadcastReceiver);
            unregisterReceiver(deliveryBroadcastReciever);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    try {
        unregisterReceiver(sendBroadcastReceiver);
        unregisterReceiver(deliveryBroadcastReciever);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
