Automated SMS app crashes

Question

I have built a test app that upon button tap sends an automated SMS with pre-defined message to a pre-defined phone number. I have used intents.

But when I tap 'button' it crashes. Any ideas? Am I missing something or implementing wrong?

CODE:

package com.ali.sms;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    Button button;

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

        button=(Button)findViewById(R.id.button);

        button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
            // TODO Auto-generated method stub
                Sms();
            }
        });
    }

    void Sms(){

        Intent intent = new Intent( Intent.ACTION_SENDTO, Uri.parse("sms:0123456789"));
        intent.putExtra("sms_body", "Hello!");
        intent.setType("vnd.android-dir/mms-sms");
        startActivity(intent);
    }
}

Manifest.xml file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.ali.sms"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="19"
        android:targetSdkVersion="22" />

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        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>

In Eclipse/LogCat I'm getting this error:

android.content.ActivityNotFoundException: No Activity found to handle Intent {act=android.intent.action.SENDTO typ=vnd.android-dir/mms-sms (has extras) }

On phone error message is:

Unfortunately, SMS has stopped.

P.S. I have searched the web & stackoverflow for fixing No Activity found to handle Intent but to no avail.

Please check this related question. Send SMS via intent

The answer seems to be to simply remove the intent type.

 public void Sms() { 
     Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse("smsto:0123456789")); 
     intent.putExtra("sms_body", "Hello!"); 
     startActivity(intent); 
  }

In order to have automatic sending then consider using the SmsManager.sendTextMessage method.

    SmsManager sm = SmsManager.getDefault();
    String destinationAddress = "012345679";
    String text = "Hello";
    sm.sendTextMessage(destinationAddress, null, text, null, null);
