I am developing an android app in eclipse. I thought I named it optimuse, that is also the title of the folder eclipse created. 

But when I run the app, the name appears as "MainActivity". This is also displayed on the top of the window. 

How can I change this. I checked my manifest and it said:

```
 <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
...

```

I guess I need to change @string/app\_name. But where can I do that?

PS: I did try to fill in a string instead of @string/app\_name, but that did not change anything.

Thanks!

EDIT: 

For clarity, here is my Manifest:

```
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.dh.optimuse"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="15" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
