Andrid SMS Example

The Android framework provides full access to SMS functionality using the SmsManager class.
Make an Android project and have a main activity with name SendSMSActivity.java with the following code


package com.example.sendsms;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

public class SendSMSActivity extends Activity {
SendSMS mSender = new SendSMS();

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

public void sendit(View v) {
boolean success = mSender
.sendSMSMessage("+917829955125",
"Hi, sms application is working fine , love u :)");
Toast.makeText(
this,
"Message sent " + (success ? "successfully" : "unsuccessfully"),
Toast.LENGTH_SHORT).show();
}
}

the SendSMS.java has following code

package com.example.sendsms;

import java.util.ArrayList;

import android.telephony.SmsManager;

import android.util.Log;

/** The code for dealing with the SMS manager; 

 * called from the GUI code.

 */

public class SendSMS {

    static String TAG = "SendSMS";

    SmsManager mSMSManager = null;

    /* The list of message parts our messge

     * gets broken up into by SmsManger */

    ArrayList<String> mFragmentList = null;

    /* Service Center - not used */

    String mServiceCentreAddr = null;

SendSMS() {

mSMSManager = SmsManager.getDefault();

}

/* Called from the GUI to send one message to one destination */

public boolean sendSMSMessage(

String aDestinationAddress,

String aMessageText) {

if (mSMSManager == null) {

return (false);

}

mFragmentList = mSMSManager.divideMessage(aMessageText);

int fragmentCount = mFragmentList.size();

if (fragmentCount > 1) {

Log.d(TAG, "Sending " + fragmentCount + " parts");

mSMSManager.sendMultipartTextMessage(aDestinationAddress, 

mServiceCentreAddr,

mFragmentList, null, null);

} else {

Log.d(TAG, "Sendine one part");

mSMSManager.sendTextMessage(aDestinationAddress, 

mServiceCentreAddr,

aMessageText, null, null);

}

return true;

}

}

the main.xml is having the following layout

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/hello" />

    

    <Button

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/send"

        android:onClick="sendit"/>

</LinearLayout>

Set the permission in the AndroidManifest XML file to send SMS:

<uses-permission android:name="android.permission.SEND_SMS">
