Android app does not start after changing startup activity

I have created a simple android app and I am trying to create another startup activity. The app executed (with the old start activity) when my manifest said:

    <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".EnrollActivity"
        android:label="@string/title_activity_enroll" >
    </activity>
    <activity
        android:name=".RecordActivity"
        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>

      

        
        
        
      

    

I changed the activity section to:

        <activity
        android:name=".EnrollActivity"
        android:label="@string/title_activity_enroll" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".RecordActivity"
        android:label="@string/app_name" >
    </activity>

      

        
        
        
      

    

Now when I press the start button, nothing launches on my connected device. However, a launcher icon called EnrollActivity is added on my device and if I click on it, it works as expected.

How do I get the start button to start the application again (with the correct name)?
