<h1>Overview<a class="headerlink" href="#overview" title="Permalink to this headline">¶</a></h1>
<p>The android_core stack is currently under active development. Consider all
APIs and documentation to be volatile.</p>
<p><a class="reference external" href="javadoc/index.html">Javadoc</a> is used extensively and cross referenced from
this documentation.</p>

<h2>ROS-enabling Android applications<a class="headerlink" href="#ros-enabling-android-applications" title="Permalink to this headline">¶</a></h2>
<p>android_core provides <a class="reference external" href="http://developer.android.com/guide/developing/projects/index.html#LibraryProjects">Android Library Projects</a> to help you write ROS
applications for Android. The library projects are named for the <a class="reference external" href="http://developer.android.com/guide/appendix/api-levels.html">Android API
level</a> they require (e.g. android_gingerbread_mr1 and android_honeycomb_mr2).
Each class or feature is defined in the library project that represents the
minimum version of Android required for it to work.</p>
<p>Your application can depend on multiple library projects. This allows you to
easily target your application for different API levels.</p>
<p>Beyond specific features, android_core defines the pattern of combining the
Android <a class="reference external" href="http://developer.android.com/reference/android/view/View.html">View</a> and <a class="reference external" href="javadoc/org/ros/node/NodeMain.html#">NodeMain</a> concepts to enable the
development of data driven Android UIs (e.g.
<a class="reference external" href="javadoc/org/ros/android/view/RosTextView.html#">RosTextView</a>).</p>

<div class="section" id="android-gingerbread-mr1-library-project">
<h2>android_gingerbread_mr1 library project<a class="headerlink" href="#android-gingerbread-mr1-library-project" title="Permalink to this headline">¶</a></h2>
<p>android_gingerbread_mr1 (API level 10) is the lowest API level supported. It
provides the base <a class="reference external" href="http://developer.android.com/reference/android/app/Activity.html">Activity</a> (<a class="reference external" href="javadoc/org/ros/android/RosActivity.html#">RosActivity</a>) and
<a class="reference external" href="http://developer.android.com/reference/android/app/Service.html">Service</a> (<a class="reference external" href="javadoc/org/ros/android/NodeMainExecutorService.html#">NodeMainExecutorService</a>) for executing
and managing the lifecycle of your <a class="reference external" href="javadoc/org/ros/node/NodeMain.html#">NodeMain</a>s.</p>
<p>A few of the other features provided include:</p>
<ul class="simple">
<li>camera publisher</li>
<li>image view</li>
<li>orientation publisher</li>

<h2>android_honeycomb_mr2 library project<a class="headerlink" href="#android-honeycomb-mr2-library-project" title="Permalink to this headline">¶</a></h2>
<p>android_honeycomb_mr2 (API level 13) provides features that require multitouch
and other APIs that are only available in devices with Android Honeycomb MR2 or
higher.</p>
