Unexpected Top-Level Exception after SDK Update
问题 I'm working on an Android Project which has an Android Library Project in his Build Path. Both projects have the AdWhirl SDK library in their libs folder and Build Path. Now since updating android sdk tools to r15 the ant build of the main project fails on following exception: [dx] UNEXPECTED TOP-LEVEL EXCEPTION: [dx] java.lang.IllegalArgumentException: already added: Lcom/adwhirl/AdWhirlLayout$AdWhirlInterface; [dx] at com.android.dx.dex.file.ClassDefsSection.add(ClassDefsSection.java:123)
