java - Android + Apache POI 我需要读取 .docx 并转换为文本

Question

我需要阅读 .docx 并转换为文本。我正在尝试使用 Apache POI 库，但出现了一些错误

构建.gradle

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "by.roman.irtov.apachepoi"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

    compileOptions {
        sourceCompatibility = 1.8
        targetCompatibility = 1.8
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.core:core-ktx:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'org.apache.poi:poi:4.1.0'
    implementation 'org.apache.poi:poi-ooxml:4.1.0'
}

申请

class App : MultiDexApplication() {

    override fun onCreate() {
        super.onCreate()
        MultiDex.install(this)
    }
}

block 正在读取 docx

private fun readDocx(){
        try {
            val dir = Environment.getExternalStorageDirectory()
            val yourFile = File(dir, "test.docx")
            val opcPackage = OPCPackage.open(yourFile, PackageAccess.READ)
            val docx = XWPFDocument(opcPackage)
            val wx = XWPFWordExtractor(docx)
            val text = wx.text
        } catch (ex: Exception) {
            ex.printStackTrace()
        }
    }

在线 - val docx = XWPFDocument(opcPackage) 我发现错误 ->

谁知道如何正确使用 Apache Poi？安卓上可以吗？有工作示例吗？ (Apache POI 用于 .docx 到文本)
