- Overview
- ========
- The android_core stack is currently under active development. Consider all
- APIs and documentation to be volatile.
- `Javadoc <javadoc/index.html>`_ is used extensively and cross referenced from
- this documentation.
- ROS-enabling Android applications
- ----------------------------------
- android_core provides `Android Library Projects`_ to help you write ROS
- applications for Android. The library projects are named for the `Android API
- level`_ 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.
- Your application can depend on multiple library projects. This allows you to
- easily target your application for different API levels.
- Beyond specific features, android_core defines the pattern of combining the
- Android `View`_ and :javadoc:`org.ros.node.NodeMain` concepts to enable the
- development of data driven Android UIs (e.g.
- :javadoc:`org.ros.android.view.RosTextView`).

- .. _Android API level: http://developer.android.com/guide/appendix/api-levels.html
- .. _View: http://developer.android.com/reference/android/view/View.html
- android_gingerbread_mr1 library project
- ---------------------------------------
- android_gingerbread_mr1 (API level 10) is the lowest API level supported. It
- provides the base `Activity`_ (:javadoc:`org.ros.android.RosActivity`) and
- `Service`_ (:javadoc:`org.ros.android.NodeMainExecutorService`) for executing
- and managing the lifecycle of your :javadoc:`org.ros.node.NodeMain`\s.
- A few of the other features provided include:
- * camera publisher
- * image view
- * orientation publisher
- .. _Activity: http://developer.android.com/reference/android/app/Activity.html
- .. _Service: http://developer.android.com/reference/android/app/Service.html
- android_honeycomb_mr2 library project
- -------------------------------------
- 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.
- A few of the features provided include:
- * 2D mapping and navigation
- * 2D laser scan visualization
- * virtual joystick
