Conversion to Dalvik format failed with error 1 with javax/net/SocketFactory.class

Question

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] 1 error; aborting
[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.

Answer 1

I had the same problem.. This worked for me project-->properties->java build path->libraries-> remove all including android jars

now go the project browser, right click on the project you are working on, then android tools---> fix project properties... do a clean and then build...

Answer 2

• I solved the problem (at least for me).

Here's what I did:

• Go to Project » Properties » Java Build Path » Libraries
• Remove all except the "Android X.Y" click OK.
• Go to Project » Clean » Clean projects selected below » select your project and click OK.

That did the trick for me. Hope it works for you as well

Update: well actually I might have to retract my opinion.. the actions removed the error messages but now I am missing certain classes and methods... arggghhhh
