appcompat 21 logo as back button

After update sdk to 21 version logo doesn't display. I display logo using following code:

actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setIcon(R.drawable.ic_launcher);

The code looks: https://i.sstatic.net/fAWIx.png

This code:

actionBar.setDisplayShowHomeEnabled(true);
actionBar.setIcon(R.drawable.ic_launcher);

Looks: https://i.sstatic.net/hkYqa.png

This code:

actionBar.setDisplayHomeAsUpEnabled(true);

Here's what worked for me if using an icon 

actionBar.setIcon(R.drawable.ic_app_icon);
actionBar.setDisplayShowHomeEnabled(true);

Or, if you want a wider logo 

actionBar.setLogo(R.drawable.ic_app_logo);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayUseLogoEnabled(true);

Per the Toolbar documentation:

  • A title and subtitle. The title should be a signpost for the Toolbar's current position in the navigation hierarchy and the content contained there. The subtitle, if present should indicate any extended information about the current content. If an app uses a logo image it should strongly consider omitting a title and subtitle.

In modern Android UIs developers should lean more on a visually distinct color scheme for toolbars than on their application icon. The use of application icon plus title as a standard layout is discouraged on API 21 devices and newer.

However, if you want an application icon, setLogo() is indeed the correct method.
