I followed this article.

When I did 'rosmake android_app_chooser', I got the error message as below.

How can I solve this problem?

  /opt/rocon_elec/android/android_gingerbread/build.xml:4: The following error occurred while executing this line:
  /opt/rocon_elec/rosjava_core/rosjava_bootstrap/android.xml:46: taskdef class cannot be found

There is [/opt/android-sdk-linux/tools/lib/anttasks.jar] file. and the jar file has AaptExecTask.class. but the error message show this message in verbose mode. [ Caused by: java.lang.ClassNotFoundException: ]

Sorry, just to be clear. You checked the jar file that is listed first in the classpath for the class AaptExecLoopTask.class?

Hi, Yes, I extracted [${sdk.dir}/tools/lib/anttasks.jar] file($sdk.dir=/opt/android-sdk-linux, rosjava_bootstrap/android.xml) and checked. Thank you for your concern.

This is actually due to a change in the new version of Android tools. You'll have to fix rosjava_bootstrap/android.xml to make this work. See

FYI, this is now fixed.
