转换为Dalvik格式失败：无法执行dex：定义了多个dex文件

Question

I'm getting an error at runtime stating: "DraggableGridViewSample] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/animoto/android/views/DraggableGridView$1;"

How might this be avoided? I've tried removing the android-support-v4 jar from my libs folder and clicking Android Tools > Add Android Support Library but I cannot seem to resolve this issue.

Any suggestions are greatly appreciated.

Answer 1

Looking at the source you provided, the DraggableGridView class is already under src . So adding the jar that contains the same is redundant and dex will complain about duplicate definitions.

To fix it, just remove the DraggableGridView.jar from your project.

Answer 2

Project - build Path - Libraries.
Check if android private libraries contains the same jars listed in the libraries in the first place. If so remove private libraries and leave the jars.
That worked for me.

Answer 3

从外部将所有jars添加到libs文件夹中，然后取消选中应该可用的android私有库
