Android: remove left margin from actionbar’s custom layout

I am using a custom actionbar view, and as you can see in the screenshot below, there is a blank gray space in the actionbar. I want to remove it.

What have I done:

res/values-v11/styles.xml

<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">
        <item name="android:actionBarStyle">@style/ActionBarStyle</item>
        <item name="actionBarStyle">@style/ActionBarStyle</item>
</style>

res/values/my_custom_actionbar.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="ActionBarStyle" parent="@style/Widget.AppCompat.Light.ActionBar.Solid">
        <item name="android:height">60dp</item>
    </style>
</resources>

Manifest

<uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="19" />

<application
            android:icon="@drawable/ic_launcher"
            android:label="@string/AppName"
            android:theme="@style/AppBaseTheme" >
    <!-- activities... etc -->
</application>

MainActivity

public void onCreate(Bundle bundle) {
    super.onCreate(bundle);

    ActionBar actionbar = getSupportActionBar();

    actionbar.setDefaultDisplayHomeAsUpEnabled(false);
    actionbar.setDisplayHomeAsUpEnabled(false);
    actionbar.setDisplayShowCustomEnabled(true);
    actionbar.setDisplayShowHomeEnabled(false);
    actionbar.setDisplayShowTitleEnabled(false);
    actionbar.setDisplayUseLogoEnabled(false);
    actionbar.setHomeButtonEnabled(false);

    // Add the custom layout
    View view = LayoutInflater.from(this).inflate(R.layout.actionbar, null, false);
    actionbar.setCustomView(view);
}

I have found a recent post, that is pointing out that there is an issue with the latest release. I have also updated ADT and SDK to Android 5.

Android ActionBar’s custom view not filling parent

I don’t know what should I do.

Edit (partial solution):

Not working on Android <= API 10.

Android Lollipop, AppCompat ActionBar custom view doesn’t take up whole screen width

What have I changed:

Use the latest sdk version:

<uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="21" />

Add a toolbarStyle:

<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">
        <item name="android:actionBarStyle">@style/ActionBarStyle</item>
        <item name="actionBarStyle">@style/ActionBarStyle</item>

        <item name="android:toolbarStyle">@style/ToolbarStyle</item>
        <item name="toolbarStyle">@style/ToolbarStyle</item>
</style>

<style name="ToolbarStyle" parent="@style/Widget.AppCompat.Toolbar">
    <item name="contentInsetStart">0dp</item>
    <item name="android:contentInsetStart">0dp</item>
</style>
