这个是什么情况？？怎么解决

承易

这些警告和错误信息表明您在尝试编译或打包一个包含Apache POI以及其他相关库（如DOM4J、XMLBeans等）的Java项目时遇到了问题。该项目目标是运行在Android平台上，但在处理过程中的desugaring阶段（用于兼容低版本Android API的方法转换）缺失了一些必要的类。

例如，许多警告显示了诸如java.awt.*、javax.imageio.*、org.apache.commons.logging.*、javax.swing.* 等类找不到，这些都是Java标准版（Java SE）中的类，它们并不包含在Android SDK中，所以无法在Android环境中运行。

此外，还有关于dex文件方法数超过限制的错误：

Error: Cannot fit requested classes in a single dex file (# methods: 111805 > 65536). Try supplying a main-dex list

这意味着您的应用中引用的类和方法数量超过了Dalvik Executable (DEX) 文件的最大方法数限制（默认是65536个方法）。要解决这个问题，通常有以下几种方法：

Proguard优化：启用代码压缩和混淆，可以减少最终APK中的方法数量。

Multidex支持：对于Android 5.0 噜阿噜lipop之前的版本，需要开启multidex支持，允许应用分多个DEX文件存储方法。

在模块级别的build.gradle文件中添加 multidex 支持：

Groovy
android {
    defaultConfig {
        multiDexEnabled true
    }
}
dependencies {
    implementation 'com.android.support:multidex:1.0.3' // 或者更新的版本
}
如果是应用主入口（通常是Application类），继承自MultiDexApplication。

提供main-dex列表：手动指定哪些类必须包含在主DEX文件中，以确保核心功能正常运行。

综上所述，由于POI库主要用于处理Microsoft Office文档，其依赖的大量Java SE库并不适合Android环境。如果要在Android上处理Office文档，建议寻找专门为Android设计的库，如Apache POI的某些子项目或者第三方的Android友好的库，如andOTP或docx4j-for-android等。对于Android上的Excel操作，可以考虑使用像androidxlsx这样的库。

这个要启用apk分包机制，免费版用不了。
