here is what works for me like a dream: in the Activity I have this:

    //hiding default app icon
    ActionBar actionBar = getActionBar();
    actionBar.setDisplayShowHomeEnabled(false);
    //displaying custom ActionBar
    View mActionBarView = getLayoutInflater().inflate(R.layout.my_action_bar, null);
    actionBar.setCustomView(mActionBarView);
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM)

my_action_bar.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/turquoise">

    <ImageButton 
        android:id="@+id/btn_slide"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:background="@null"
        android:scaleType="centerInside"
        android:src="@drawable/btn_slide"
        android:paddingRight="50dp"
        android:onClick="toggleMenu"
        android:paddingTop="4dp"/>
</RelativeLayout>

//use your custom xml view to show your icon at left

View actionBarView = getLayoutInflater().inflate(R.layout.action_bar_custom_view, null);
        actionBar.setCustomView(actionBarView);
        actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

on your onCreate() method if you are on the activity

actionBar.addTab(actionBar.newTab()
.setIcon(<the icon you want>)
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
