Sorry i can't reply as a comment, but i'm guessing you want to change the actionbar overflow menu icon. If so you can do it in styles.xml.

 <!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>

<!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme -->
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
    <item name="android:src">@drawable/ic_launcher</item>
</style>

Sorry I don't have enough reputation to post a comment. Here is the best answer I found, its one line of code:

myToolbar.setOverflowIcon(ContextCompat.getDrawable(getApplicationContext(),R.drawable.my_drawable));
