HoloAdd this to the topic
myActionBar.setDisplayHomeAsUpEnabled(true);

I see the application logo (in my case, mm_logosee below) in the upper left edge, and this logo acts as a cursor button
The Materiallogo is not displayed

but if i add
myActionBar.setDisplayShowHomeEnabled(true);
the application icon is displayed in the upper left edge (in my case, ic_launchersee below)
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:logo="@drawable/mm_logo"
android:label="@string/app_name"
android:theme="@style/Theme.GreenAppTheme"
android:largeHeap="true">
If I add both of these lines
myActionBar.setDisplayShowHomeEnabled(true);
myActionBar.setDisplayUseLogoEnabled(true);
The logo is also displayed in the Material, but tends to fill the space highlighted with buttons with a too high left edge and does not act as a cursor button (this is a simple static image). Here is an example:
