Encounter this problem when trying to Build Project getting such output in console:

[2010-07-19 23:29:23 - myProject]
trouble processing "javax/net/SocketFactory.class":
[2010-07-19 23:29:23 - myProject] 
Attempt to include a core VM class in something other than a core library.
It is likely that you have attempted to include the core library from a desktop
virtual machine into an application, which will most assuredly not work. If
you really intend to build a core library -- which is only appropriate as
part of creating a full virtual machine binary, as opposed to compiling an
application -- then use the "--core-library" option to suppress this error
message. If you go ahead and use "--core-library" but are in fact building
an application, then please be aware that your build will still fail at some
point; you will simply be denied the pleasure of reading this helpful error
message.

[2010-07-19 23:29:23 - myProject] Conversion to Dalvik format failed with error 1

I was looking for my project to use the package javax, not found, clean all also does not help. what I am doing wrong?

Update

Sorry guys, but I could not find good fix for that, I want to emphasize the fact, that i dont use SocketFactory class in my project at all! source code was not changed before this problem, and that's why i think that problem in eclipse or adt or something else, BUT if i use ant(generated by sdk) to build this project there is no problem!!!

I solve this problem by removing Eclipse, Android SDK, Eclipse workspace, and just reinstall them, after this all works fine for now.

Hope this will help someone.

Under certain conditions it gets its knickers in a twist and the best fix I've found is to remove referenced jars, clean, add them back in and then compile again.

I believe the error can be caused by including the same classes twice.

This error will also occur (and you won't be able to get rid of it by cleaning) when using classes that are not part of the Android environment.

To summarise the information in the link bimbim.in provided (well my understanding when I glanced over it)

  • The Android Davik VM tries to compile the jars but finds some stuff that it can't compile to .dex files

so

  • Just create a "lib" directory in the root of the project (where the src, bin res directories are) and add them to the build path. Project Properties... Java Build Path... Libraries.. Add JARs..

I could resolve this issue by creating a new project, looks like the some project settings were creating this issue and could not really find the root cause for that. But, dumping the existing source code onto the new project resovled this issue. If anyone has found the root cause for this problem pls do let me know.

Whenever the Project is having the ambitious data. This problem is caused. May be android can't able to find which one choose.
