Send a SMS via intent

I want to send an SMS via intent, but when I use this code, it redirects me to a wrong contact:

Intent intentt = new Intent(Intent.ACTION_VIEW);         
intentt.setData(Uri.parse("sms:"));
intentt.setType("vnd.android-dir/mms-sms");
intentt.putExtra(Intent.EXTRA_TEXT, "");
intentt.putExtra("address",  phone number);
context.startActivity(intentt);

Why?

Also, I know a way to follow SMS sending, but I do not know how code this:

Starting activity: Intent { 
   act=android.intent.action.SENDTO dat=smsto:%2B**XXXXXXXXXXXX** flg=0x14000000    
   cmp=com.android.mms/.ui.ComposeMessageActivity }

where XXXXXXXXXXXX is phone number.

I have developed this functionality from one Blog. There are 2 ways you can send SMS.

1. Open native SMS composer
2. write your message and send from your Android application

This is the code of 1st method.

Main.xml

<?xml version="1.0" encoding="utf-8"?>  
    <RelativeLayout  
        android:id="@+id/relativeLayout1"  
        android:layout_width="fill_parent"  
        android:layout_height="fill_parent"  
        xmlns:android="http://schemas.android.com/apk/res/android">  
      
            <Button  
                android:id="@+id/btnSendSMS"  
               android:layout_height="wrap_content"  
               android:layout_width="wrap_content"  
               android:text="Send SMS"  
               android:layout_centerInParent="true"  
               android:onClick="sendSMS">  
           </Button>  
   </RelativeLayout>

Activity

public class SendSMSActivity extends Activity {  
     /** Called when the activity is first created. */  
     @Override  
     public void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  
      }  
   
     public void sendSMS(View v)  
     {  
         String number = "12346556";  // The number on which you want to send SMS  
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", number, null)));  
     }  
    /* or 
     public void sendSMS(View v) 
      { 
     Uri uri = Uri.parse("smsto:12346556"); 
         Intent it = new Intent(Intent.ACTION_SENDTO, uri); 
         it.putExtra("sms_body", "Here you can set the SMS text to be sent"); 
         startActivity(it); 
      } */  
 }

NOTE:- In this method, you don’t require SEND_SMS permission inside the AndroidManifest.xml file.

For 2nd method refer to this BLOG. You will find a good explanation from here.

Hope this will help you...

Uri uri = Uri.parse("smsto:YOUR_SMS_NUMBER");   
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);   
intent.putExtra("sms_body", "The SMS text");   
startActivity(intent);  

Create the intent like this:

Intent smsIntent = new Intent(android.content.Intent.ACTION_VIEW);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address","your desired phoneNumber");         
smsIntent.putExtra("sms_body","your desired message");
smsIntent.setFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(smsIntent);

Try this code. It will work

Uri smsUri = Uri.parse("tel:123456");
Intent intent = new Intent(Intent.ACTION_VIEW, smsUri);
intent.putExtra("sms_body", "sms text");
intent.setType("vnd.android-dir/mms-sms"); 
startActivity(intent);

Hope this will help you.

If you want a certain message, use this:

String phoneNo = "";//The phone number you want to text
String sms= "";//The message you want to text to the phone

Intent smsIntent = new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", phoneNo, null));
smsIntent.putExtra("sms_body",sms);
startActivity(smsIntent);

   Uri uriSms = Uri.parse("smsto:1234567899");   
   Intent intentSMS = new Intent(Intent.ACTION_SENDTO, uriSms);   
   intentSMS.putExtra("sms_body", "The SMS text");   
   startActivity(intentSMS); 

Hope this is work, this is working in my app

SmsManager.getDefault().sendTextMessage("Phone Number", null, "Message", null, null);

/**
 * Intent to Send SMS
 * 
 *
 * Extras:
 *
 * "subject"
 *      A string for the message subject (usually for MMS only).
 * "sms_body"
 * 	    A string for the text message.
 *  EXTRA_STREAM
 *      A Uri pointing to the image or video to attach.
 *

 * @param phoneNumber on which SMS to send
 * @param message text Message to send with SMS
 */
public void startSMSIntent(String phoneNumber, String message) {
	Intent intent = new Intent(Intent.ACTION_SENDTO);
	// This ensures only SMS apps respond
	intent.setData(Uri.parse("smsto:"+phoneNumber));
	intent.putExtra("sms_body", message);
	if (intent.resolveActivity(getPackageManager()) != null) {
		startActivity(intent);
	}
}

1. Manifest permission (you can put it after or before "application" )

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

2. make a button for example and write the below code ( as written before by Prem at this thread ) and replace the below phone_Number by an actual number, it will work:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", "phone_Number", null)));

Add try-catch otherwise phones without sim will crash.

void sentMessage(String msg) {
    try {
        Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.setType("vnd.android-dir/mms-sms");
        smsIntent.putExtra("sms_body", msg);
        startActivity(smsIntent);
    } catch (Exception e) {
        e.printStackTrace();
        Toast.makeText(this, "No SIM Found", Toast.LENGTH_LONG).show();
    }
}
