Trying to use rosAndroid with Fuerte. As far as I can tell, I have to first install and build rosjava_core, then rosjava_android, then I can follow the tutorial here (which seems to suggest it is OK to start here but it fails miserably): http://www.ros.org/wiki/rosjava/Tutorials/Creating%20a%20ROS%20Android%20project

So, after some searching, I find and complete "Intalling rosjava_core": http://docs.rosjava.googlecode.com/hg/rosjava_core/html/installing.html and then move onto "Building rosjava_core": http://docs.rosjava.googlecode.com/hg/rosjava_core/html/building.html but get these errors, seem to be missing posedetection_msgs:

:rosjava_messages:compileJava /home/dbarry/rosAndroid/rosjava_core/rosjava_messages/build/generated-src/siftviewer/ProcessImageCluster.java:19: package posedetection_msgs does not exist java.util.List<posedetection_msgs.feature0d> getFeatures(); ^ /home/dbarry/rosAndroid/rosjava_core/rosjava_messages/build/generated-src/siftviewer/ProcessImageCluster.java:20: package posedetection_msgs does not exist void setFeatures(java.util.List<posedetection_msgs.feature0d> value);

Where do I get posedetection_msgs?

Bigger question-- is there an easier way to start using ROS Android?

Here is a partial answer. Search for a while and find that posedetection_msgs is part of jsk-ros-pkg, see here: http://ros.org/wiki/jsk-ros-pkg#jsk_android_apps and download with svn: svn co https://jsk-ros-pkg.svn.sourceforge.net/svnroot/jsk-ros-pkg/trunk add the path to ROS_PACKAGE_PATH and then rosmake posedetection_msgs

Then go back to rosAndroid and now ./gradlew install works.

Unfortunately, ./gradlew tests fails with these messages: Test org.ros.internal.message.MessageSerializationTest FAILED Test org.ros.time.NtpTimeProviderTest FAILED

Building > :rosjava:test > 131 tests completed, 17 failures The test reports show the following details: java.util.NoSuchElementException: Resource does not exist: /std_msgs/msg/Bool.msg java.util.NoSuchElementException: Resource does not exist: /std_msgs/msg/Duration.msg .... many more similar.

but /opt/ros/fuerte/share/std_msgs/msg/Bool.msg does exist and rospack find std_msgs returns: /opt/ros/fuerte/share/std_msgs

However, this still seems like a long walk for a short drink, so I suspect I am on the wrong path to just getting some ROS Android code to compile......

I just pushed a fix for the failing tests.
