android office转pdf插件,Android word/Excel文档转PDF

首先grable文件导入jar包,

implementation 'org.apache.poi:poi:3.17'

// Excel XLS

implementation 'org.apache.poi:poi-ooxml:3.17'

// Excel XLSX DOCX

implementation 'org.apache.poi:poi-scratchpad:3.17'

// Word DOC

implementation 'org.apache.poi:poi-ooxml-schemas:3.17'

implementation files('libs/xdocreport-2.0.1.jar')

implementation files('libs/rt.jar')

//项目要使用iText

implementation 'com.itextpdf:itextpdf:5.5.13.1'

implementation 'com.itextpdf.tool:xmlworker:5.5.11'

implementation 'org.apache.xmlbeans:xmlbeans:3.1.0'

implementation 'org.apache.commons:commons-collections4:4.4'

//输出中文,还要引入下面itext-asian.jar包

implementation 'com.itextpdf:itext-asian:5.2.0'

implementation 'org.jsoup:jsoup:1.11.3'

运行项目中可能会有重复包或文件,在grable的android中添加:

packagingOptions {

exclude 'com/itextpdf/text/pdf/fonts/cmap_info.txt'

exclude 'MATE-INF/LICENSE'

}

解决重复引入包的问题。
