[android-developers] Re: NoClassDefFoundError for gson after updating the ADT and SDK Tools
Just mark all your JARs and Eclipse User Libraries as exported in the Build Path / Order and Export configuration. It didn't work for me until I also put Android Dependencies before my libraries in the forementioned tab. Still don't know what the order is supposed to do. :D On Mar 22, 1:06 pm, Luca Morettoni l...@morettoni.net wrote: On Thu, Mar 22, 2012 at 12:03 PM, Mark Murphy mmur...@commonsware.com wrote: You can try: http://android.foxykeep.com/dev/how-to-fix-the-classdefnotfounderror-... thanks! -- Luca Morettoni luca(AT)morettoni.net |http://www.morettoni.net gtalk/msn: luca(AT)morettoni.net |http://twitter.com/morettoni Google+ profile:http://bit.ly/morettoni_plus Member of Python User Group Perugia:http://www.pypg.org/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: NoClassDefFoundError for gson after updating the ADT and SDK Tools
Just updated to tools 17 and got this in most projects: Implicit super constructor Object() is undefined for default constructor. Must define an explicit constructor And The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object.Fix the build path then try building this project Fix Project Properties fixed some projects, but not all. What did help was: I brought up project Properties / Android, selected a different Android API version, clicked Apply, then changed the API version back to what it was and clicked Apply again. The improvements in these new tools are very welcome, but come on, does anyone ever test how well new tools can migrate existing projects? -- K 22 марта 2012 г. 16:12 пользователь Yasin YILDIRIM yasinyildirim...@gmail.com написал: It worked!

[android-developers] Re: NoClassDefFoundError when running the app
Well, remember that the jar file CONTAINS class files. In a normal JDK environment the jar doesn't need to be compiled, since it already is. But in Android the contents of the jar does need to get included into the dex file(s) which end up in the apk.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
According to me, you should also add the gdata-base and gdata-client. Perhaps, here are the super classes of CalendarService. Try it once and I am sure that this will work.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
I too am encountering the same issue. I'm using MOTODEV to develop an Android app using the Google Calendar API. I downloaded gdata-src.java-1.40.3 and unzipped it. In Project - Properties I pull up the Java Build Path tab, Libraries subtab and click Add External Jars. I navigate down to gdata-src.java-1.40.3/ gdata/java/lib, and inside there are like 50 jar files. I'm a noob but I admit this seems odd straight away - why so many? So I pick gdata-calendar-2.0.jar and click through and I'm happy to see that my compile now reads clean, plus there is a new Referenced Libraries entry (peer to src, assets, etc.) and that it is populated with 5 jar files: calendar, calendar-meta, client, client-meta, and core. Sweet, looks like dependencies are handled too. (Noob here, and if my method sucks I invite instruction). Upon run (in the Emulator) I get a force close and the logcat shows a stack traceback for a java.lang.NoClassDefFoundError: com.google.gdata.client.calendar.CalendarService at this line: CalendarService myCalendar = new CalendarService(dcd-Timeline-1); I've looked round lots and don't see where I can tell the runtime how to find this... I would have thought it would be statically compiled into my .apk?? thanks, DJC On Mar 15, 11:52 am, Brion Emde brione2...@gmail.com wrote: Hi Tom, I went down the same path as you with the gdata library and I was going to take a look at this library, which the developer claims does work on Android: http://code.google.com/p/simply-gdata/ I'd be interested in if this works for you, as I haven't gotten around to looking at it and if it solves my medium-term needs.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
Hi Tom, I went down the same path as you with the gdata library and I was going to take a look at this library, which the developer claims does work on Android: http://code.google.com/p/simply-gdata/ I'd be interested in if this works for you, as I haven't gotten around to looking at it and if it solves my medium-term needs.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
I created the libs directory where you specified and copied the gdata .jar files in there, then from Eclipse ran Export project, then installed on the phone - but with the same result - NoClassDefFoundError for CalendarService. It seems that Eclipse is silently failing to handle the gdata jar files somehow - my project contains another 3rd party jar file which appears to work just fine. Something tells me that I have to stop relying on Eclipse and actually learn how to use the Android SDK command-line tools... I knew it wouldn't be this easy. ;-) Thanks for all of your help.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
What I do is to create a libs/ directory in Eclipse, and add them to the Eclipse build path. Android Tools/Export Signed Application Properties works fine. But I *highly* recommend not using Eclipse for your production builds, but rather have a build script that handles checkout, version numbering, naming the resulting builds, etc. A disciplined build process greatly reduces the possibility of confusion and mistakes making it into customer's hands. Unforutnately, the way Eclipse does things, that means two different build methodologies; one for debugging, one for production. Fortunately, the Eclipse side of that is generally pretty painless, and the 'android' command gives you a leg up on an ant script for the production builds. But as to your problem. If you have a 3rd party jar file which is working fine, and it's set up the same way, then the way it's set up isn't really the problem. You need to find out what the problem is. NoClassDefFoundError does not mean what you think it means. Reading the name, you'd think it means what ClassNotFoundException means. No, what it means is that while LOADING a class, and probably while actually running the static initializers of a class, an exception was encountered. If that happens, you don't get a reference to the class, and NoClassDefFoundError is thrown. Unfortunately, you don't get told what the problem was. So you have to use the debugger to figure it out. Set an exception breakpoint on NoClassDefFoundError, and ones for Exception and Error, and run your code. This should expose what the original problem was. I can never understand why NoClassDefFoundError doesn't include the original cause -- it really makes such problems a lot more obscure than they need to be.

[android-developers] Re: NoClassDefFoundError for gdata CalendarService class
It doesn't really matter if you create a lib folder and put the jars and link them. It just works if you have added the jars the the build path. Though I am not able to figure out why you are getting this error. But I *highly* recommend not using Eclipse for your production builds, but rather have a build script that handles checkout, version numbering, naming the resulting builds, etc. Well, as far as developing with Eclipse is concerned, I would say that eclipse is the best and the only IDE available for Android. You can also try Motodev Studio, but that's almost similar to eclipse. Learning Android command line tools is great, but eclipse does make your development and publishing task a lot easier.
