What is wrong with my Android style attributes, actionbar title hidden or no color?

Question

I'm trying to customize ActionBar using styles.xml on KITKAT and older versions.

This is as far I got it, but missing actionbar title, no color inserted properly, height or what is wrong?

Here is my styles.xml

<style name="Theme.MyApp" parent="AppTheme">
    <item name="actionBarStyle">@style/Theme.MyApp.ActionBar</item>
    <item name="android:actionBarStyle">@style/Theme.MyApp.ActionBar</item>
</style>

<style name="Theme.MyApp.ActionBar" parent="style/Theme.MyApp">
    <item name="elevation">4dp</item>
    <item name="android:height">56dp</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:icon">@drawable/icon_placeholder_compat</item>
    <item name="android:background">@color/blue</item>
    <item name="android:titleTextStyle">@style/Theme.MyApp.ActionBar.TitleTextStyle</item>
    <item name="titleTextStyle">@style/Theme.MyApp.ActionBar.TitleTextStyle</item>
</style>

<style name="Theme.MyApp.ActionBar.TitleTextStyle" parent="style/Theme.MyApp.ActionBar">
    <item name="android:textColor">@color/white</item>
    <item name="android:color">@color/white</item>
</style>

For change color of action bar and status bar:

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/action_bar_color</item>
    <item name="colorPrimaryDark">@color/status_bar_color</item>
</style>
