starting from api 16 the up navigation was introduced and needs to be set in the activity tag. To ensure compatibility with appcompat for versions below 16 the meta-data tag is used, so you need this line for it to work:

<activity
        android:name=".activity.ProductsListActivity"
        android:label="@string/title_activity_products_list"
        android:screenOrientation="portrait"

        android:parentActivityName="com.ef.umall.activity.HomeActivity"

        android:theme="@style/CustomActivityTheme" >
         <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.ef.umall.activity.HomeActivity" />
</activity>
