Hi,
I followed the instructions on the webpage(http://docs.rosjava.googlecode.com/hg/rosjava_core/html/index.html and http://docs.rosjava.googlecode.com/hg/android_core/html/index.html) to download, install and build rosjava and android_core on my computer. I got 100% "BUILD SUCCESSFUL" except a bunch of warnings while building android_tutorial_% package. The warning all look like these:
[dx] warning: Ignoring InnerClasses attribute for an anonymous inner class
[dx] (jnamed$1) that doesn't come with an
[dx] associated EnclosingMethod attribute. This class was probably produced by a
[dx] compiler that did not target the modern .class file format. The recommended
[dx] solution is to recompile the class from source, using an up-to-date compiler
[dx] and without specifying any "-target" type options. The consequence of ignoring
[dx] this warning is that reflective operations on this class will incorrectly
[dx] indicate that it is *not* an inner class.
Also, when I import the android_tutorial_image_transport into eclipse, I can not launch it in the emulator and got the following errors:
