原因:java.lang.NoSuchMethodError:没有静态方法newFactory()

Question

我正在构建一个Android应用程序，在尝试读取XLSX文件时，面临一个非静态方法异常。

尝试了所有的可能性，如更新应用程序/build.gradle中的依赖关系，但没有成功。

请帮助我解决此问题。

我正在添加app.gradle文件。其他代码是使用XSSF的基本XLSX文件读取。当我试图在Spring Suite工具中运行这个java片段时，它运行正常。然而，当我将这些java片段集成到Android应用程序中时，它导致了这个运行时异常。

应用分级：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion '27.0.3'
defaultConfig {

检查您是否在apk上应用了任何混淆，如果是，则需要保留这些包和类，以便它们不会被proguard剥离。
