Activities and the manifest in Android

I know there are plenty of questions about this but I just can't work out why my program keeps loading the wrong activity even though I've made the correct one the default in the manifest. Here's some code for you all:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="swin.examples"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name="swin.examples.TemperatureConvertor"
                  android:label="@string/app_name">
        </activity>        
        <activity android:name="swin.examples.FeetToCmConvertor"
                  android:label="@string/app_name">
        </activity>
        <activity android:name="swin.examples.Main" 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>

And here's where I think the problem will be if it's not in the manifest:

package swin.examples;

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

public class Main extends Activity 
{

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        initializeUI();
    }

private void initializeUI()
{
    Button btnCm = (Button)findViewById(R.id.btnFeet);
    btnCm.setOnClickListener(btnFeetListener);
    Button convertButton = (Button)findViewById(R.id.btnTemp);
    convertButton.setOnClickListener(btnTempListener);

}

/** Handle convert button click */ 
private OnClickListener btnTempListener = new OnClickListener() 
{
    public void onClick(View v) 
    {
            convertButtonClicked();
    }
};

private OnClickListener btnFeetListener = new OnClickListener() 
{
    public void onClick(View v) 
    {
            btnCmClicked();
    }
};

private void btnCmClicked()
{
    // set the sender and the receiver of the intent
    Intent intent = new Intent();
    intent.setClass(getApplicationContext(), swin.examples.FeetToCmConvertor.class);

    startActivity(intent); // transmit your intent

}

private void convertButtonClicked()
{
    // set the sender and the receiver of the intent
    Intent intent = new Intent();
    intent.setClass(getApplicationContext(), swin.examples.TemperatureConvertor.class);

    startActivity(intent); // transmit your intent  
}
}

I can't work it out and I hope you can help me! Thank you so much in advance!

EDIT: Code updated, but still doesn't work. If this helps, this is the log messages:

Proper IntentFilter for the main Activity is

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
