解决方案

由于直接使用 Apache POI 中的库时会遇到各种问题，因此 Apache POI 目前无法在开箱即用的 Android 手机上运行.Android 对作为 jar 文件一部分的重复类更加严格，不幸的是 XmlBeans 在它的 jar 文件中有这样的重复类.

有两个项目试图在 Android 上使用 Apache POI:

• https://github.com/andruhon/android5xlsx(适用于 Android 5)和 https://github.com/andruhon/AndroidReadXLSX(适用于 Android 4)，两者目前仍基于 Apache兴趣点 3.12
• https://github.com/centic9/poi-on-android/(对于Android 5，由我维护)，可以更轻松地使用较新版本的POI重新编译，例如它目前使用 3.16-beta2

I added 5 jar files of Apache POI so that I can save an text as .docx document but I can't run the application first I had 210 error in the grade now i have this error can someone please help me ..!? i followed this example https://www.tutorialspoint.com/apache_poi_word/apache_poi_word_quick_guide.htm

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
    applicationId "com.example.mike.textword"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled = true

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
 }

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
testCompile 'junit:junit:4.12'
compile files('libs/dom4j-1.6.jar')
compile files('libs/poi-3.16-beta2.jar')
compile files('libs/poi-ooxml-3.16-beta2.jar')
compile files('libs/poi-ooxml-schemas-3.16-beta2.jar')
compile files('libs/xmlbeans-2.6.0.jar')
compile 'com.android.support:multidex:1.0.1'
 }

and now i have this error!

Error:Execution failed for task    ':app:transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/xmlbeans/xml/stream/Location.class

解决方案

Currently Apache POI will not work on your Android Phone out of the box due to various problems that you will run into when using the libraries from Apache POI directly. Android is more strict about duplicate classes as part of the jar-files and unfortunately XmlBeans has such duplicate classes in it's jar-file.

There are two projects that try to make it possible to use Apache POI on Android:

• https://github.com/andruhon/android5xlsx (for Android 5) and https://github.com/andruhon/AndroidReadXLSX (for Android 4), both are currently still based on Apache POI 3.12
• https://github.com/centic9/poi-on-android/ (for Android 5, maintained by me), which can be more easily recompiled with newer versions of POI, e.g. it uses 3.16-beta2 currently
