Write the permission code in Android-Manifest.xml file

You need to write SEND_SMS permission as given below:

1. <uses-permission android:name="android.permission.SEND_SMS"/>  
2.    

File: Android-Manifest.xml

1. <?xml version="1.0" encoding="utf-8"?>  
2. <manifest   
3. xmlns:androclass="http://schemas.android.com/apk/res/android"  
4.     package="com.example.sendsms"  
5.     android:versionCode="1"  
6.     android:versionName="1.0" >  
7.   
8.     <uses-sdk  
9.         android:minSdkVersion="8"  
10.         android:targetSdkVersion="16" />  
11.   
12.     <uses-permission android:name="android.permission.SEND_SMS"/>  
13.     
14.     <uses-permission android:name="android.permission.RECEIVE_SMS"/>  
15.   
16.     <application  
17.         android:allowBackup="true"  
18.         android:icon="@drawable/ic_launcher"  
19.         android:label="@string/app_name"  
20.         android:theme="@style/AppTheme" >  
21.         <activity  
22.             android:name="com.example.sendsms.MainActivity"  
23.             android:label="@string/app_name" >  
24.             <intent-filter>  
25.                 <action android:name="android.intent.action.MAIN" />  
26.   
27.                 <category android:name="android.intent.category.LAUNCHER" />  
28.             </intent-filter>  
29.         </activity>  
30.     </application>  
31.   
32. </manifest>

Activity class

Let's write the code to make the phone call via intent.

File: MainActivity.java

1. package com.example.sendsms;  
2.   
3. import android.os.Bundle;  
4. import android.app.Activity;  
5. import android.app.PendingIntent;  
6. import android.content.Intent;  
7. import android.telephony.SmsManager;  
8. import android.view.Menu;  
9. import android.view.View;  
10. import android.view.View.OnClickListener;  
11. import android.widget.Button;  
12. import android.widget.EditText;  
13. import android.widget.Toast;  
14.   
15. public class MainActivity extends Activity {  
16.   
17.     EditText mobileno,message;  
18.     Button sendsms;  
19.     @Override  
20.     protected void onCreate(Bundle savedInstanceState) {  
21.         super.onCreate(savedInstanceState);  
22.         setContentView(R.layout.activity_main);  
23.           
24.         mobileno=(EditText)findViewById(R.id.editText1);  
25.         message=(EditText)findViewById(R.id.editText2);  
26.         sendsms=(Button)findViewById(R.id.button1);  
27.           
28.     //Performing action on button click  
29.         sendsms.setOnClickListener(new OnClickListener() {  
30.               
31.             @Override  
32.             public void onClick(View arg0) {  
33.                 String no=mobileno.getText().toString();  
34.                 String msg=message.getText().toString();  
35.                   
36.                 //Getting intent and PendingIntent instance  
37.                 Intent intent=new Intent(getApplicationContext(),MainActivity.class);  
38.                 PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent,0);  
39.                   
40.                 //Get the SmsManager instance and call the sendTextMessage method to send message  
41.                 SmsManager sms=SmsManager.getDefault();  
42.                 sms.sendTextMessage(no, null, msg, pi,null);  
43.                   
44.                 Toast.makeText(getApplicationContext(), "Message Sent successfully!",  
45.                     Toast.LENGTH_LONG).show();  
46.             }  
47.         });  
48.     }  
49.   
50.     @Override  
51.     public boolean onCreateOptionsMenu(Menu menu) {  
52.         // Inflate the menu; this adds items to the action bar if it is present.  
53.         getMenuInflater().inflate(R.menu.activity_main, menu);  
54.         return true;  
55.     }  
56.       
57. }
