For getting Apache POI to work on Android,I need to get Stack to work on Android. Following this question:Using JAXB with Google Android and @Sean Barbeau's answer.I successfully converted all the jar's to android compatible ones including the Apache POI library but it still gives me this run time error:

06-22 01:06:52.461 14865-14865/com.quizwiz.sharmakritya.poi E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.quizwiz.sharmakritya.poi, PID: 14865 edu.usf.cutr.javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.EventFactory not found at edu.usf.cutr.javax.xml.stream.FactoryFinder.newInstance(FactoryFinder.java:72) at edu.usf.cutr.javax.xml.stream.FactoryFinder.find(FactoryFinder.java:176) at edu.usf.cutr.javax.xml.stream.FactoryFinder.find(FactoryFinder.java:92) at edu.usf.cutr.javax.xml.stream.XMLEventFactory.newInstance(XMLEventFactory.java:30) at org.apache.poi.openxml4j.opc.internal.marshallers.PackagePropertiesMarshaller.<clinit>(PackagePropertiesMarshaller.java:41) at org.apache.poi.openxml4j.opc.OPCPackage.init(OPCPackage.java:162) at org.apache.poi.openxml4j.opc.OPCPackage.<init>(OPCPackage.java:142) at org.apache.poi.openxml4j.opc.Package.<init>(Package.java:37) at org.apache.poi.openxml4j.opc.ZipPackage.<init>(ZipPackage.java:87) at org.apache.poi.openxml4j.opc.OPCPackage.open(OPCPackage.java:273) at org.apache.poi.xslf.usermodel.XMLSlideShow.empty(XMLSlideShow.java:103) at org.apache.poi.xslf.usermodel.XMLSlideShow.<init>(XMLSlideShow.java:75) at com.quizwiz.sharmakritya.poi.PPT.onCreate(PPT.java:16) at android.app.Activity.performCreate(Activity.java:5451) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1093) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2377) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2471) at android.app.ActivityThread.access$900(ActivityThread.java:175) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1308) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:146) at android.app.ActivityThread.main(ActivityThread.java:5602) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1283) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1099) at dalvik.system.NativeStart.main(Native Method)

The crux of the whole error is android is missing the package com.bea.xml.stream. How do I resolve this ?

I tried resolving this on my own by downloading an external jar from here. But that gave me strange errors:

Note: removing the com.bea.stax.impl_1.2.0.jar from Gradle Dependencies gets me back to the first error.

Please help me find a way to use the package com.bea.xml.stream on android.UPDATE

The dependencies before your answer in gradle:

apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.2" packagingOptions{ exclude 'Meta-INF/DEPENDENCIES' exclude 'Meta-INF/NOTICE' exclude 'Meta-INF/NOTICE.txt' exclude 'Meta-INF/LICENSE' exclude 'Meta-INF/LICENSE.txt' } defaultConfig { applicationId "com.quizwiz.sharmakritya.poi" minSdkVersion 16 targetSdkVersion 21 versionCode 1 versionName "1.0" multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile 'com.android.support:appcompat-v7:21.0.3' compile 'com.android.support:multidex:1.0.0' compile files('libs/stax-api-android-1.0-2.jar') compile files('libs/stax2-api-android-3.1.1.jar') //compile files('libs/com.bea.stax.impl_1.2.0.jar') compile files('libs/poi-3.12-20150511.jar') compile files('libs/poi-ooxml-3.12-20150511.jar') compile files('libs/poi-ooxml-schemas-3.12-20150511.jar'){ exclude group: 'stax', module: 'stax-api' } compile files('libs/xmlbeans-2.6.0.jar') compile files('libs/stax-1.2.0_rc2-dev.jar') }

UPDATE #2The error while compilation I get:

 Error:duplicate files during packaging of APK C:\Users\sharmakritya\AndroidStudioProjects\POI\app\build\outputs\apk\app-debug-unaligned.apk Path in archive: Meta-INF/services/javax.xml.stream.XMLInputFactory Origin 1: C:\Users\sharmakritya\AndroidStudioProjects\POI\app\build\intermediates\javaResources\debug\Meta-INF\services\javax.xml.stream.XMLInputFactory Origin 2: C:\Users\sharmakritya\.gradle\caches\modules-2\files-2.1\edu.usf.cutr.android.xml\aalto-xml-android\0.9.8\bf4e7339b028f92638b36ab9ac3cc3314a860d1\aalto-xml-android-0.9.8.jar You can ignore those files in your build.gradle: android { packagingOptions { exclude 'Meta-INF/services/javax.xml.stream.XMLInputFactory' } } Error:Execution Failed for task ':app:packageDebug'. > Duplicate files copied in APK Meta-INF/services/javax.xml.stream.XMLInputFactory File 1: C:\Users\sharmakritya\AndroidStudioProjects\POI\app\build\intermediates\javaResources\debug\Meta-INF\services\javax.xml.stream.XMLInputFactory File 2: C:\Users\sharmakritya\AndroidStudioProjects\POI\app\build\intermediates\javaResources\debug\Meta-INF\services\javax.xml.stream.XMLInputFactory

Try using the pre-packaged JARs from the CUTR Maven repo for stax and Aalto:

apply plugin: 'com.android.application' repositories { mavenCentral() maven { // CUTR SNAPSHOTs url "https://github.com/CUTR-at-USF/cutr-mvn-repo/raw/master/snapshots" } maven { // CUTR Releases url "https://github.com/CUTR-at-USF/cutr-mvn-repo/raw/master/releases" } } android { compileSdkVersion 21 buildToolsVersion "21.1.2" packagingOptions{ // exclude 'Meta-INF/DEPENDENCIES' <--- and try commenting this out,I don't believe it should be needed exclude 'Meta-INF/NOTICE' exclude 'Meta-INF/NOTICE.txt' exclude 'Meta-INF/LICENSE' exclude 'Meta-INF/LICENSE.txt' pickFirst 'Meta-INF/services/javax.xml.stream.XMLInputFactory' } defaultConfig { applicationId "com.quizwiz.sharmakritya.poi" minSdkVersion 16 targetSdkVersion 21 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile 'com.android.support:appcompat-v7:21.0.3' compile files('libs/poi-3.12-20150511.jar') compile files('libs/poi-ooxml-3.12-20150511.jar') compile files('libs/poi-ooxml-schemas-3.12-20150511.jar'){ compile files('libs/xmlbeans-2.6.0.jar') // JSR173 APIs compile 'edu.usf.cutr.android.xml:stax2-api-android:3.1.1' compile 'edu.usf.cutr.android.xml:stax-api-android:1.0-2' // JSR173 provider implementation - Aalto compile 'edu.usf.cutr.android.xml:aalto-xml-android:0.9.8' }

I believe the main issue here is that Apache POI depends on JSR173 Streaming API for XML,which depends on the platform (in our case Android) being able to provide an implementation and underlying XML parsing provider. Android doesn't support JSR173,so it can't find a provider - com.bea.xml.stream.EventFactory is the default provider,and it can't even find that one (see JAXB marshalling exception javax.xml.stream.FactoryConfigurationError running with Java 5 for more details on this topic).

@L_404_6@ is an open-source JSR173 provider,so you should be able to use this in place of the BEA implementation (com.bea.xml.stream.EventFactory). The Aalto archive (JAR file) includes the necessary registration (under Meta-INF/services/javax.xml.stream.XMLInputFactory file,that points to the Aalto class com.fasterxml.aalto.stax.InputFactoryImpl) that should allow a Java platform to recognize it as a JSR173 implementation. As a result,you should no longer get the edu.usf.cutr.javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.EventFactory not found error,because Android should recognize that Aalto is an available provider,and use Aalto instead.

Note - apparently there are bugs with prevIoUs versions of ADT for Eclipse and Gradle plugin < 0.7.0 that strips the /Meta-INF/* files from the JARs during the build process. It seems like >= v0.7.0 shouldn't have the problem according to Google,but from others' reports it sounds like it still may be problematic,and could potentially remove the Meta-INF/services/javax.xml.stream.XMLInputFactory file,which is required for the platform to register Aalto.

If the above doesn't work,try the workaround mentioned in AOSP issue 59658 comment 22:

1. right click on /src/main (where you have /java and /res folders),
2. select New > Folder > Java Resources Folder,
3. click Finish (do not change Folder Location),
4. right click on new /resources folder,
5. select New > Directory
6. enter "Meta-INF" (without quotes),
7. right click on /resources/Meta-INF folder,
8. select New > Directory
9. enter "services" (without quotes)
10. copy any file you need into /resources/Meta-INF/services

For you,in step 10 above you'd need to copy this file (javax.xml.stream.XMLInputFactory) into /resources/Meta-INF/services.

If the above doesn't work,I also noticed that you have a exclude 'Meta-INF/DEPENDENCIES' in your packagingOptions - I'd remove this,as I don't believe you should need that line,and it may be causing problems with registering Aalto as well.

You could also check out some other solutions/work that people have done trying to get Apache POI working on Android:

• Creating/Reading an Excel file in Android

After upgrading POI from 3.9 to 3.15 we were getting a:

javax.xml.stream.FactoryConfigurationError: Provider for class javax.xml.stream.XMLEventFactory cannot be created

Besides POI,our build included:

compile ('com.msopentech.odatajclient:odatajclient-engine:0.9.0')

it turned out that the odatajclient jar included a java.xml.stream.XMLEventFactory file in its Meta-INF\services,the contain of that file was com.fasterxml.aalto.stax.EventFactoryImpl but the aalto included in odatajclient was old and com.fasterxml.aalto.stax.EventFactoryImpl was finally inheriting from com.msopentech.javax.xml.stream.XMLEventFactory instead of java.xml.stream.XMLEventFactory class.

At run time POI was using the java.xml.stream.XMLEventFactory,the class loader returned com.fasterxml.aalto.stax.EventFactoryImpl and the cast to java.xml.stream.XMLEventFactory Failed.

The solution was excluding the module that included the old aalto:

compile ('com.msopentech.odatajclient:odatajclient-engine:0.9.0') { exclude group: 'com.msopentech.odatajclient', module: 'odatajclient-engine-xml' }
