ActionBar ignoring icon

Question

I'm slowly moving my app to Android Lollipop, in fact I'm just beginning this process.

But I'm already having some problems. The first one is that I can't make the icon appear in the ActionBar again. Just the app name and buttons appear.

Here is my style:

<style name="AppTheme" parent="AppTheme.Base"/>

    <style name="AppTheme.Base" parent="Theme.AppCompat.Light">
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">true</item>
        <item name="actionBarStyle">@style/MyApp.Widget.ActionBar.Solid</item>
        <item name="actionBarTabStyle">@style/MyApp.Widget.ActionBarTabStyle</item>
        <item name="actionModeBackground">@drawable/cab_background_top_MyApp</item>
        <item name="actionModeSplitBackground">@drawable/cab_background_bottom_MyApp</item>
        <item name="actionModeCloseButtonStyle">@style/MyApp.Widget.ActionButton.CloseMode</item>
        <item name="actionBarItemBackground">@drawable/selectable_background_MyApp</item>
    </style>

<style name="MyApp.Widget.ActionBar.Solid" parent="@style/Widget.AppCompat.Light.ActionBar.Solid">
        <item name="android:logo">@drawable/ic_launcher</item>
        <item name="background">@drawable/actionbar_background</item>
        <item name="backgroundStacked">@drawable/ab_stacked_solid_MyApp</item>
        <item name="backgroundSplit">@drawable/ab_bottom_solid_MyApp</item>
        <item name="progressBarStyle">@style/MyApp.Widget.ProgressBar</item>
    </style>

And here is my AndroidManifest:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:name=".MyApp"
        android:theme="@style/AppTheme" >
<activity
            android:name="com.br.myapp.MainActivity"
            android:label="@string/explore"
            android:launchMode="singleTop"
            android:screenOrientation="portrait" >

        </activity>

</application>

And my activity class is extending ActionBarActivity from the AppCompat library v21.

Try adding the following two lines in onCreate of your main Activity:

getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.your_actionbar_icon);
