我正在整合POI来阅读PPTx，我正在使用以下jar，我已经尝试了大部分的jar。所以请告诉我在android studio中集成POI以正确阅读PPTx的方法。我不知道我收到此错误的原因。
implementation files('libs/poi-ooxml-3.9.jar')
implementation files('libs/poi-3.9.jar')
implementation files('libs/xmlbeans-2.6.0.jar')
implementation files('libs/dom4j-1.6.1.jar')
implementation files('libs/commons-collections4-4.1.jar')
implementation files('libs/commons-codec-1.10.jar')
implementation files('libs/poi-scratchpad-3.9.jar')
并收到此错误。
