kotlin – Android Apache POI error when reading Microsoft Word document: org.apache.xmlbeans.SchemaTypeLoaderException Cannot resolve type for handle-ThrowExceptions

Exception or error:

I am trying to use Apache POI in my Android application so that I can read Microsoft Word files. I am integrating the POIA library which enables Apache POI usage on Android (https://github.com/SUPERCILEX/poi-android). However, when I run my code and read in a Word file, I receive the following error:

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

Below is my code (I am receiving error on the first line):

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

At runtime I have the following code:

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")

Below is my gradle (project-level):

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

buildscript {
    ext.kotlin_version = '1.3.60'
    repositories {

    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 {
        maven { url 'https://jitpack.io' }

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

Below is my gradle (app-level):

    implementation ("com.github.SUPERCILEX.poi-android:poi:$poiVersion") {
        exclude group: 'stax', module: 'stax-api'

Below is the full stack trace:

IMPORTANT: I am trying to read in the contents of a Word file the USER SELECTED, not a Word file from a hardcoded path.

Please include ALL the relevant code in your answer, and your code should work on Android API 22.

How to solve:

owner of the lib here. poi-android has only been tested with Excel files and is tailored to work well with proguard to minimize binary size for an app I wrote.

If I had to guess, 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 into your source tree and add this Gradle dependency: implementation files('path/to/file.jar'). However, as you’ll notice, the lib is quite large (13MB+), hence the reasoning behind modifying POI to my use case. I would recommend forking one of the libs and tailoring it to your use case.


Did you add proper packagingOptions in build.gradle ?

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

Also enable multiDexEnabled
