Padding between ActionBar's home icon and title

EDIT: make sure you set this drawable as LOGO, not as your app icon like some of the commenters did.

Just make an XML drawable and put it in the resource folder "drawable" (without any density or other configuration).

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:drawable="@drawable/my_logo"
        android:right="10dp"/>


</layer-list>

The last step is to set this new drawable as logo in your manifest (or on the Actionbar object in your activity)

Good luck!

I adapted Cliffus answer and assigned the logo-drawable in my actionbar style definition, for instance like this in res/style.xml:

<item name="android:actionBarStyle">@style/MyActionBar</item>

<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:background">#3f51b5</item>
        <item name="android:titleTextStyle">@style/ActionBar.TitleText</item>
        <item name="android:textColor">#fff</item>
        <item name="android:textSize">18sp</item>
        <item name="android:logo">@drawable/actionbar_space_between_icon_and_title</item>
</style>

The drawable looks like Cliffus' one (here with the default app launcher icon) in res/drawable/actionbar_space_between_icon_and_title.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@drawable/ic_launcher"
        android:right="20dp"/>
</layer-list>

In the android_manifest.xml you can still set a different app icon (launcher icon on 'desktop'. Any different logo definition here are visible in activities without an action bar.

I also faced a similar issue, in my case I had to set titles dynamically on each activity depending on the content.

So this worked for me.

actionBar.setTitle("  " + yourActivityTitle);

If all you want is the spacing, this is the easiest solution I could think of.
