Hide App Icon On Navigation Drawer Home Button

In my Nexus 5 (without physical buttons) it's alright, my action bar is as follow: This is what I want for all devices. Instead, in devices with physical buttons, this happens: W

Solution 1:

Set custom style for ActionBar like this:

<stylename="ActionBar"parent="android:Widget.Holo.ActionBar">
    ...
    <itemname="android:icon">@android:color/transparent</item><!-- Hide logo from the action bar --></style>

thin set this style in application theme following way:

<itemname="android:actionBarStyle">@style/ActionBar</item>

where:

<colorname="transparent">#00000000</color>

Good luck!
