Creating a SMS Application in Android?

Question

I am creating an SMS Application to send and receive SMS.

I am able to send SMS using the following code:

SmsManager sms = SmsManager.getDefault();
         


        

Answer 1

What you need to do is register a BroadcastReceiver object. Check out this article for more information.

If you want to hide SMS messages from the primary inbox, you'll need to delete them from the SMS ContentProvider and use your own SQLite database to store them. Also be sure to mark them as read in the content provider to remove the notification from the tray.

Answer 2

U can send and recieve message using SMSMAnager class. U can implement custom Reciever that on msg recieved it will notify user that message has arrived.. Here i am attaching code that i have written to send and receive message using Custom Broadcast reciever, It might be useful to u. Note: This is for the version 1.6 above..So make sure that u do it in 2.0 or 2.2 preferably.

Go through it and try to implement it..

public class SMS extends Activity {

 Button btnSendSMS;
 EditText txtPhoneNo;
 EditText txtMessage;
 Button addcontact;
 EditText phonePhoneno;


 private static final int CONTACT_PICKER_RESULT = 1001;
 private static final String DEBUG_TAG = "";

 String phoneNo="";
 String phonenofromcontact="";
 String finallistofnumberstosendmsg ="";


 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
    txtMessage = (EditText) findViewById(R.id.txtMessage);
    addcontact =(Button) findViewById(R.id.addphonenofromcontact);


    addcontact.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View V)
        {
            Intent ContactPickerIntent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
            startActivityForResult(ContactPickerIntent, CONTACT_PICKER_RESULT);             
        }
    }
    );

    btnSendSMS.setOnClickListener(new View.OnClickListener() 
    {

            String phoneNo1=  phonePhoneno.getText().toString(); 

            // Sending message to both the written and added contact...

I don't think you can place sms in different inboxes and you don't listen to a port to get SMS you use a BroadcastReceiver.

I would recommend you to go through the open source smspopup app to get a better idea of how things work for sms in general.

You can send your this received broadcast to your main activity using intent. And on your main activity receive this intent and append the data to the list view as a inbox.

OR the bast but lengthy way

Add this data (received number and message) to the SQL database and on the main activity fatch the data from data base and append to the list view called inbox.In this way your inbox data will be saved even if the phone is switched off or if application is shut down.
