Answer 1

Lollipop doesn't show logo by default so set:

 getSupportActionBar().setDisplayShowHomeEnabled(true);
 getSupportActionBar().setLogo(R.drawable.ic_launcher);
 getSupportActionBar().setDisplayUseLogoEnabled(true);

Answer 2

For targetSDKversion API 21, in your activity's onCreate(...)

setSupportActionBar(your_toolbar); 
getSupportActionBar().setIcon(R.drawable.ic_launcher);

For targetSDKversion lower than API 21, in your AndroidManifest:

<application
    ... ...
    android:logo="@drawable/ic_launcher"
    ... ...

</application>

If you want to show logo in action bar

In main.xml

 <item 
    android:id="@+id/abc_image"
    android:title="abc"
    android:icon="@drawable/abcImage"
    android:showAsAction="always"/>
<item
    android:id="@+id/bb"
    android:title="second"
    android:icon="@drawable/bbImage"
    app:showAsAction="always"/>

In MainActivity

    getActionBar().setCustomView(R.layout.actionbar);
    getActionBar().setDisplayShowCustomEnabled(true);
    getActionBar().setDisplayUseLogoEnabled(true);
    getActionBar().setDisplayShowHomeEnabled(false);
    getActionBar().setHomeButtonEnabled(true);
