Hiding an Application's title in Android 4

I was trying to hide an application’s title from the Action bar. The first possible approach was a nasty hack: just setting the label to an empty string, like this

android:label=""

in the Manifest. However, choosing this approach leads you into two problems:

The application’s name, below the icon, will be blank
You won’t see the app in the “recent apps” list

Googling (for some time) led my to this StackOverflow’s answer. It’s basically what we are looking for, with just a tiny adjustment: we are going to remove the ActionBarSherlock part, since we are using Android 4.0+. So, in the styles.xml file, the code will look like this:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
        <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
    </style>

    <style name="Widget.Styled.ActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid.Inverse">
        <item name="android:displayOptions">showHome|useLogo</item>
        <item name="displayOptions">showHome|useLogo</item>
    </style>

</resources>

Of course, our new style needs to be referenced from the Manifest, like this:

<application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    ...

That’s it! Hope you’ll find it useful
