Send SMS in android

by

To send SMS in Android, either the SmsManager API or devices Built-in SMS application can be used, i.e., in Android, the Intent can be used to send SMS.

Syntax: SmsManager API:

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("phoneNo", null, "sms message", null, null);

Syntax: Built-in SMS application:

Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.putExtra("sms_body", "default content"); 
sendIntent.setType("vnd.android-dir/mms-sms");
startActivity(sendIntent);

Example: Send SMS in android using Intent:

//Getting intent and PendingIntent instance  
Intent intent=new Intent(getApplicationContext(),MainActivity.class);  
PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent,0);  
 
//Get the SmsManager instance and call the sendTextMessage method to send message                 
SmsManager sms=SmsManager.getDefault();  
sms.sendTextMessage("123456789", null, "Hello World", pi,null);

Example:

activity_main.xml:

In the activity_main.xml file, we will drag two EditTexts, two Textviews, and a button from the palette.

        android:layout_marginLeft="34dp"
        android:layout_marginTop="48dp"
        android:text="Send" />
 
</RelativeLayout>

AndroidManifest.xml:

In the AndroidManifest.xml file, we will write the SEND_SMS permission code.

Syntax:

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

File: AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.radioapp" >
    android:versionCode="1"
    android:versionName="1.0" >
 
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />
 
    <uses-permission android:name="android.permission.SEND_SMS"/>
 
    <uses-permission android:name="android.permission.RECEIVE_SMS"/>
 
    <application
        android:allowBackup="true"
        android:icon="@drawable/java"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
 
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
 
</manifest>

Activity class:(File: MainActivity.java)

In the MainActivity.java file, we will write the code to make the phone call via intent.

package com.example.radioapp;
 
import android.os.Bundle;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.telephony.SmsManager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
 
public class MainActivity extends Activity {
 
    EditText mobileno,message;
    Button sendsms;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        mobileno=(EditText)findViewById(R.id.editText1);
        message=(EditText)findViewById(R.id.editText2);
        sendsms=(Button)findViewById(R.id.button1);
 
        //Performing action on button click
        sendsms.setOnClickListener(new OnClickListener() {
 
            @Override
            public void onClick(View arg0) {
                String no=mobileno.getText().toString();
                String msg=message.getText().toString();
 
                //Getting intent and PendingIntent instance
                Intent intent=new Intent(getApplicationContext(),MainActivity.class);
                PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent,0);
 
                //Get the SmsManager instance and call the sendTextMessage method to send message
                SmsManager sms=SmsManager.getDefault();
                sms.sendTextMessage(no, null, msg, pi,null);
 
                Toast.makeText(getApplicationContext(), "Message Sent!!",
                        Toast.LENGTH_LONG).show();
            }
        });
    }
 
 
}
