SMS BroadcastReceiver, Reading Complete SMS

Using BroadcastReceiver, allows the system to get alert whenever a message received. Upon message reception, you can handle as per requirement. A message may be composed of multi-parts, so, you can combine it and show as a single complete message. Following is the onReceive method:

@Override

public void onReceive(Context context, Intent intent) {        
    

    // Get the data (SMS data) bound to intent
    StringBuilder text=new StringBuilder();
    
    // Retrieves a map of extended data from the intent.    

    final Bundle bundle = intent.getExtras();
    Log.d(TAG, "onReceive");
    try {

        if (bundle != null) {

            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int parts = 0; parts < pdusObj.length; parts++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[parts]);

                String senderNumber = currentMessage.getDisplayOriginatingAddress();
                String message = currentMessage.getDisplayMessageBody();

                Log.i("SmsReceiver", "senderNumber: "+ senderNumber + "; message: " + message);
                text.append(message); //combine sms parts as a single message            } // end for loop

            // Show Alert            

            Toast.makeText(context, "Complete Message: " +text.toString() , Toast.LENGTH_LONG).show();
        } // bundle is null
    } catch (Exception e) {

        Log.e("SmsReceiver", "Exception smsReceiver" +e);
    }
 }
