<h4>Navigation bar</h4>
|
|
<p>Android 4.0 removes the need for traditional hardware keys on phones by replacing them with a
|
|
virtual navigation bar that houses the Back, Home and Recents buttons. Read the
|
|
<a href="{@docRoot}design/patterns/compatibility.html">Compatibility</a> pattern to learn how the OS adapts to
|
|
phones with hardware buttons and how pre-Android 3.0 apps that rely on menu keys are supported.</p>

<h4>Action bar</h4>
|
|
<p>The action bar is the most important structural element of an Android app. It provides consistent
|
|
navigation across the platform and allows your app to surface actions.</p>

<h4>Multi-pane layouts</h4>
|
|
<p>Creating apps that scale well across different form factors and screen sizes is important in the
|
|
Android world. Multi-pane layouts allow you to combine different activities that show separately on
|
|
smaller devices into richer compound views for tablets.</p>

<h4>Selection</h4>
|
|
<p>The long press gesture which was traditionally used to show contextual actions for objects is now
|
|
used for data selection. When selecting data, contextual action bars allow you to surface actions.</p>
