Fehler beim Dex mit einem Projekt mit Javafx und Apache POI

Question

Ich versuche, Apache POI auf Android zu verwenden, um das zu tun, habe ich ein Großprojekt auf Eclipse erstellt, aber wenn ich die Task AndroidInstall Gradle Task ausführen, bekomme ich einen Fehler während der Dex-Schritt. (Run Aufgabe arbeitet)

hier den Fehler:

ich gelesen, dass ich brauchte diese hinzufügen zu ignorieren Warnung aber ich bekomme einen anderen Fehler auf compileSdkVersion

lintOptions { 
    abortOnError false 
} 

und hier ist mein build.gradle Datei:

buildscript { 
    repositories { 
     jcenter() 
    } 

    dependencies { 
     classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b8' 
    } 
} 

apply plugin: 'org.javafxports.jfxmobile' 

mainClassName = "JavaFXStage" 
version = '1.0' 

repositories { 
    jcenter() 
} 

jfxmobile { 
    ios { 
     forceLinkClasses = ['ensemble.**.*'] 
    } 

    android { 

     javafxportsVersion = '8u40-b5' 
     compileSdkVersion = 23  
     applicationPackage = 'any.package.name' 

    } 
} 

dependencies{ 
    def poiVersion = "3.10.1" 
    compile "org.apache.poi:poi:${poiVersion}" 
    compile "org.apache.poi:poi-ooxml:${poiVersion}" 
    compile "org.apache.poi:ooxml-schemas:1.1" 
    compile "org.apache.xmlbeans:xmlbeans:2.6.0" 
} 

Wenn Sie weitere Informationen über das Projekt benötigen, zögern Sie nicht Fragen.

Wenn Sie irgendwelche Tipps haben, um mein Problem zu lösen, danke.

Answer 1

Verwendung von Apache POI auf Android nicht aus der Box zu einer Reihe von Einschränkungen aufgrund nicht funktioniert. Einer davon ist die Tatsache, dass das xmlbeans-jar mehrere Klassen enthält, was den Android-Compiler verwirrt. Es gibt auch Probleme mit dem Code von pacakge javax und die Größe des Codes.

Es gibt derzeit zwei Projekte, die versuchen, dieses Problem zu lösen:

• https://github.com/centic9/poi-on-android/ (von mir gehalten)
• https://github.com/andruhon/android5xlsx

Beide versuchen, dies zu lösen, indem sie wieder Verpacken der Klassen in eine kompaktere JAR-Datei, die dann zu einer Android-Anwendung hinzugefügt werden kann. Android5xlsx basiert auf POI 3.12 aktuell, poi-on-android auf 3.15-beta1 und kann relativ leicht gegen neuere Versionen von POI neu gebaut werden.

Answer 2

löste ich den Fehler im Schritt Dex von XMLBeans im gradle.build ausgenommen:

compile 'org.apache.poi:poi:3.16' 
compile ('org.apache.poi:poi-ooxml:3.16') { 
    exclude group: 'org.apache.xmlbeans', module: 'xmlbeans' 
} 

In meinem Java-Code, den ich nicht XMLBeans aber andere Parser benutzt haben. Hier ist meine Importliste:

import org.apache.poi.hssf.usermodel.HSSFCell; 
import org.apache.poi.hssf.usermodel.HSSFRow; 
import org.apache.poi.hssf.usermodel.HSSFSheet; 
import org.apache.poi.hssf.usermodel.HSSFWorkbook; 

import org.apache.poi.xssf.usermodel.XSSFCell; 
import org.apache.poi.xssf.usermodel.XSSFRow; 
import org.apache.poi.xssf.usermodel.XSSFSheet; 
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
