在Android Studio中添加元數據提取器庫

Question

我正在嘗試在我的android studio項目中添加metadata-extractor-2.8.1.jar 。

但是，每次我點擊“添加為庫”時， jar文件都不會添加。 僅記錄Null pointer exception 。

以下是異常消息：

我將metadata-extractor-2.6.4.jar添加到我的項目中，並且工作正常。 但是我確實需要2.8.1帶來的升級。

很感謝任何形式的幫助！ 另外，在此先感謝:)

使用Maven依賴項，並像這樣添加它

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

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