这里有一个类似的问题,但答案规定了将Facebook SDK添加到项目的导入方法的解决方案.任何建议将不胜感激.

Answer 1

通过将libs包含该bolts.jar文件的文件夹重新复制回Facebook模块来解决问题(请注意,我在问题中提供的第一个链接中的一条指令是删除libs文件夹),然后在Facebook模块中更改以下内容:build.gradle文件.

 compile files('../libs/bolts.jar')

至

  compile files('./libs/bolts.jar')

注意第一个中的单个点而不是双点.之后,执行sync project with gradle files操作,错误将消失.
