It is not obvious to me why 'dx' step fails to read your classes. I added some hints how to make this report more complete. Take a look at http://kenai.com/projects/nbandroid/pages/Troubleshooting and add IDE log and output from a compilation using verbose mode. Hopefully it will help us to find what is wrong with these classes.

log file from ~/.netbeans/6.7/var/log/messages.log

http://groups.google.com/group/android-developers/browse_thread/thread/ac57ffcc35c0ae3d/f0c69ca27a104774?lnk=gst&q=invalid+constant+pool+index+0000#f0c69ca27a104774 and similar posts suggest that this is not a problem of NBAndroid. More likely your toolchain has some incompatibilities - the verbose output can help us to find what is actually used.

Add also output from 'java -version' and 'dx -version' using the version of these tools that is executed during the build.

in verbose mode:

Where does your Android SDK comes from? I see that the build runs
/home/android/workbin/android-sdk-linux_x86-1.5_r2/tools/dx
and compared to mine I noticed that there is no tools/dx in my Android SDK - it should be one of the platforms/android-1.x/tools/dx.

according to this http://kenai.com/projects/nbandroid/forums/forum/topics/657-Unable-to-add-the-android-platform-in-netbean-6-5. i try to copy /home/android/workbin/android-sdk-linux_x86-1.5_r2/platforms/android1.5/* to /home/android/workbin/android-sdk-linux_x86-1.5_r2. and it merge with the folder tools in /home/android/workbin/android-sdk-linux_x86-1.5_r2/tools

here it is. i run it without copy ~/platforms/android1.5/* to /home/android/workbin/android-sdk-linux_x86-1.5_r2/

BUILD FAILED (total time: 2 seconds)

Sorry but these instructions seems bogus. Thanks for pointing to them - I added comments not to follow these anymore. Can you try from scratch with an unmodified Android SDK, empty NetBeans userdir and a new project? If this does not work it would be good to check if you can create/build and run a project using the tools in SDK itself.

yes, i tried it again from the scratch but i still facing the some problem. ok, i will try it. thanks.

problem solved. by installing openjdk-6-jre and sun-java6-jdk.
for ubuntu:
-go to terminal
-apt-get install openjdk-6-jre sun-java6-jdk

OK, thanks.
