在Android Studio中添加元数据提取器库

我正在尝试在我的android studio项目中添加metadata-extractor-2.8.1.jar。在Android Studio中添加元数据提取器库

但每次我打“添加为库” jar文件不添加。只记录一个Null pointer exception。

下面是异常消息：

我有metadata-extractor-2.6.4.jar添加到我的项目，它工作正常。但我真的需要2.8.1带来的升级。

任何帮助非常感谢！此外，在此先感谢:)

使用Maven的依赖，并在我的编译文件列表中添加像这样

compile 'com.drewnoakes:metadata-extractor:2.8.1'

http://mvnrepository.com/artifact/com.drewnoakes/metadata-extractor/2.8.1

它了。但是这个'.jar'文件在我将它添加到'Libs'中时会得到'exception'。所以这个jar甚至不能用于编译我猜。 –

尝试只是复制/粘贴，或只是将其拖入？如果没有建议的作品，请尝试再次下载，或者尝试使用旧版本进行查看。 – Kenneth

正如我在我的文章中提到的。我真的需要更新版本的'.jar'文件。 –
