Did you notice my first comment to the Blog article?

You must also define the libraries that you use in the Order & Export section of the Build Path editor – and make sure that they are defined before the Android libraries.

Unfortunately that doesn’t seem to be working. I have all my jars above my Android and Google libraries. My OpcUaSampleAppForAndroid src and gen libraries are also placed before the Android libraries. I tried playing around with this but nothing seems to be working. Should I be toggling the checkbox that is to the left side of the library and thus ‘export’ the library?

Just to clarify: I’m getting a NoClassDefFoundError, which means that the compiler is ok with everything, but the runtime isn’t. It’s complaining because when it tries to excute the line of code on line 106 of ConnectAndReadTimeTask.java:

UaClient myClient = new UaClient(serverUri);

it throws the stated error. The compiler is not complaining; this program is happily starting. However, when I try to read the time from the server, that’s when the runtime complains. Have you seen this kind of problem before?

Thanks!

Yes, you need to check every library for export: otherwise they are not copied to your Android device and cannot be found when the application starts. It’s weird that they are not checked by default.

I’m afraid that’s still not working. I’m trying to run the app on my emulator. Would you like me to send you a screenshot of my build path and order and export? Is that possible to do here?
