How to Send Sms-Android Tutorial

We can send sms in Android very easily using the smsManager By just using 4 lines of code.

SmsManager smsManager = SmsManager.getDefault();
        StringBuffer smsBody = new StringBuffer();
        smsBody.append("This is my message dude");
        //here 99999999999 is the phone number
        smsManager.sendTextMessage("9999999999", null, smsBody.toString(), null, null);
             

Don't forget to add permission to send and receive sms in Androidmanifest

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

    <uses-permission android:name="android.permission.RECEIVE_SMS"/>

Ok.Let us do it in a simple example. We are going to send an SMS to a Phone number using a button widget. When we click on the button the sms will be send  to a preset number.

 activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <Button android:text="SEND SMS"
        android:layout_width="wrap_content"
        android:onClick="sendsms"
        android:layout_height="wrap_content" />

</RelativeLayout>

MainActivity.java

package www.techizhub.com.sms;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.telephony.gsm.SmsManager;
import android.view.Menu;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void sendsms(View v)
    {
        SmsManager smsManager = SmsManager.getDefault();
        StringBuffer smsBody = new StringBuffer();
        smsBody.append("This is my message dude");
        //here 99999999999 is the phone number
        smsManager.sendTextMessage("9999999999", null, smsBody.toString(), null, null);
         Toast.makeText(MainActivity.this, "Your message send to " + "9999999999",
         Toast.LENGTH_LONG).show();


    }
}
