I have went on android and followed their instructions to style the Action Bar and it is not working. The app keeps stopping. I can see the changed color briefly as the message is shown. I have a note 2 with 4.4.2.. Here are my
styles.`
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme"
parent="@android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar"
parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:background">#F00</item>
</style>
</resources>`
manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="funnestgames.actionbar" >
<application
android:theme="@style/CustomActionBarTheme"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
>
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and my logcat.

You can change the background color by following from your mainActivity class
ActionBar actionBar = getSupportActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#C71585")));
or it will not give you error if you use following style for your actionbar
<style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
