android - Conversion to Dalvik format Failed facebook/AccessToken$SerializationProxyV1; -

[2013-02-09 19:48:50 - dex loader] unable execute dex: multiple dex files define lcom/facebook/accesstoken$serializationproxyv1; [2013-02-09 19:48:50 - mainactivity] conversion dalvik format failed: unable execute dex: multiple dex files define lcom/facebook/accesstoken$serializationproxyv1;

i tried

clean project delete libs folder restart eclipse remove android-support-v4.jar

but none of them resolve problem.

any help appreciated!!

well, depends if build facebook sdk only, or you've included library own android project (i suppose that's case). if have jar's within project folder (added jars project), remove them , re-create them somewhere outside project root, add together them 1 time again external jars. question might possible duplicate.

android android-library
