Eu tenho um projeto que usa umWelcomeActivity que se estendeFragmentActivity. Eu uso a biblioteca de suporte, entãoandroid-support-v4.jar está nolibs pasta. Quando eu corro este aplicativo, não há problemas.

No entanto, quero adicionar ActionBarSherlock ao projeto. No projeto do ABS eu usoactionbarsherlock-plugin-maps-4.1.0.jar eandroid-support-v4-r6-googlemaps.jar nolibs pasta. No meu projeto de aplicativo, eu adiciono a biblioteca ABS, e quando tento executar o aplicativo, este erro ocorre:

UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoStubImpl;

Para resolver isso, eu removi oandroid-support-v4.jar da minha applibs pasta. Quando eu inicio agora meu aplicativo, o aplicativo trava com este logcat:

Como posso consertar isso?

Eu tenho outro projeto que usa a mesma biblioteca ABS e funciona bem. Não tenho ideia do que fiz de diferente ou quais configurações estão erradas.
