It appears that:

<ul>
<li><code>android:logo</code> is available in API Level 10, but not API Level 8</li>
<li>using <code>android:logo</code> without <code>android:icon</code> does not set the application icon in the app drawer</li>
</ul>

My hunch is that "logo" refers to a company logo instead of an application icon.

 The ActionBar will use the android:logo attribute of your manifest, if
 one is provided. That lets you use separate drawable resources for the
 icon (Launcher) and the logo (ActionBar, among other things).

<hr>

<blockquote>
 setDisplayUseLogoEnabled()
 Enables the use of an alternative image (a "logo") in the Action
 Bar, instead of the default application icon. A logo is often a wider,
 more detailed image that represents the application. When this is
 enabled, the system uses the logo image defined for the application
 (or the individual activity) in the manifest file, with the
 android:logo attribute. The logo will be resized as necessary to fit
 the height of the Action Bar. (Best practice is to design the logo at
 the same size as your application icon.)

 To replace the icon with a logo, specify your application logo in the
 manifest file with the android:logo attribute, then call
 setDisplayUseLogoEnabled(true) in your activity.

The <code>&lt;application&gt;</code> tag for the Android Manifest contains a <a href="http://developer.android.com/guide/topics/manifest/application-element.html#logo" rel="noreferrer">logo attribute</a> which I have never seen before. What is the difference between your application's icon and its logo? Is it used purely for market?

Android icon vs logo

Android

Android Manifest的<application>标签包含一个我以前从未见过的。你的应用程序的图标和它的徽标有什么区别？它是纯粹用于市场的吗？
