Hide ActionBar

To hide Action bar, we need to add option in AndroidManifest.xml

<activity
            android:name="com.android.simplemovieshot.MainActivity"
            android:label="@string/app_name" 
            android:theme="@android:style/Theme.Holo.NoActionBar">
</activity>

Use NoActionBar theme.
And we can set this parameter at each Activity.
