Android 读取 Microsoft Word 文档时 Apache POI 错误：org.apache.xmlbeans.SchemaTypeLoaderException 无法解析句柄类型

Question

我正在尝试在我的 Android 应用程序中使用 Apache POI，以便我可以阅读 Microsoft Word 文件。我正在集成 POIA 库，它可以在 Android (https://github.com/SUPERCILEX/poi-android) 上启用 Apache POI。但是，当我运行我的代码并读入 Word 文件时，我收到以下错误：

Exception: org.apache.xmlbeans.SchemaTypeLoaderException: Cannot resolve type for handle _XY_Q=space|R=space

下面是我的代码（我在第一行收到错误）：

var document = XWPFDocument(uri?.let { contentResolver.openInputStream(it) });
var extractor = XWPFWordExtractor(document);
var documentText = extractor.text; // Retrieve the document's text

在运行时我有以下代码：

super.onCreate(savedInstanceState)
System.setProperty("org.apache.poi.javax.xml.stream.XMLInputFactory", "com.fasterxml.aalto.stax.InputFactoryImpl")
System.setProperty("org.apache.poi.javax.xml.stream.XMLOutputFactory", "com.fasterxml.aalto.stax.OutputFactoryImpl")
System.setProperty("org.apache.poi.javax.xml.stream.XMLEventFactory", "com.fasterxml.aalto.stax.EventFactoryImpl")

下面是我的gradle（项目级）：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.3.60'
    repositories {
        google()
        jcenter()

    }
    ext {
        poiVersion = '3.17'
    }
    dependencies {
        classpath 'com.android.tools:r8:1.4.93'
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

下面是我的gradle（应用级别）：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.diffchecker"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    // For developers using the Android Support Library
    implementation 'pub.devrel:easypermissions:2.0.1'
    implementation 'com.google.android.gms:play-services-ads:18.3.0'
    implementation ("com.github.SUPERCILEX.poi-android:poi:$poiVersion") {
        exclude group: 'stax', module: 'stax-api'
    }
}

下面是完整的堆栈跟踪：

I/System.out: Exception: org.apache.xmlbeans.SchemaTypeLoaderException: Cannot resolve type for handle _XY_Q=space|R=space@http://www.w3.org/XML/1998/namespace (schemaorg_apache_xmlbeans.system.sF1327CCA741569E70F9CA8C9AF9B44B2.cttext7f5btype) - code 13

重要提示：我正在尝试读取用户选择的 Word 文件的内容，而不是来自硬编码路径的 Word 文件。

请在您的答案中包含 ALL 相关代码，您的代码 应该适用于 Android API 22.

此处库的所有者。 poi-android 仅使用 Excel 个文件进行了测试，并且经过定制以与混淆器配合使用，以最大限度地减少我编写的应用程序的二进制文件大小。

如果我不得不猜测，this is causing your issue. For a more generic version of POI, use https://github.com/centic9/poi-on-android (which is what my lib is based off of). You'll have to include the JAR from the releases section 到您的源代码树中并添加此 Gradle 依赖项：implementation files('path/to/file.jar')。但是，您会注意到，该库非常大 (13MB+)，因此需要根据我的用例修改 POI。我建议分叉其中一个库并根据您的用例对其进行定制。

您是否在 build.gradle 中添加了正确的 packagingOptions ？

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
    }
