Replace deprecated android.support.v4.app.ActionBa

问题:

Following the answer in this question i have replaced ActionBarDrawerToggle of support v4 library that in latest update(rev 21) has been deprecated with the latest ActionBarDrawerToggle of support-v7 library.

Now the drawer works on Andrid Lollipop Emulator without deprecation warnings but when I test the app on a Jelly Bean real device no drawer and no toggle drawer button is shown.

What the hell appened with this support library update? How could I fix this issue without downgrade to previous version?

Here my layout

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!--  content view -->

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context=".MainActivity" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/drawer_text" />
    </RelativeLayout>

    <!-- nav drawer -->

    <ListView
        android:id="@+id/drawer"
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#F3F3F4"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />

</android.support.v4.widget.DrawerLayout>

1. To get ActionBarDrawerToggle v7 to work properly you need to extends your Activity class from android.support.v7.app.ActionBarActivity
2. ActionBarActivity v7 must be used with Theme.AppCompat theme from the appcompat-v7:21 support library.
3. Unless you want to switch from ActionBar to ToolBar, don't add <item name="windowActionBar">false</item> when extending Theme.AppCompat. Doing so will make your ActionBarActivity have no default ActionBar decor, and getSupportActionBar will return null. You'll need to provide your own ToolBar and call setSupportActionBar first to make getSupportActionBar work.
