To hide the Title Bar in Android Apps you need to change the android.theme property of the activity in AndroidManifest.xml to “@android:style/Theme.Black.NoTitleBar.Fullscreen”:

<activity
android:name=“.Info”
android:label=“Info”
android:screenOrientation=“portrait”
android:theme=“@android:style/Theme.Black.NoTitleBar.Fullscreen” >
</activity>
