Epublib Absturz mit EPUBReader gefunden keine Klasse

Question

Ich habe folgende Fehlermeldung:

07-03 19:45:47.341 18148-18148/? W/dalvikvm: Exception Ljava/lang/NoClassDefFoundError; thrown while initializing Lnl/siegmann/epublib/epub/EpubReader; 
07-03 19:45:47.341 18148-18148/? E/AndroidRuntime: FATAL EXCEPTION: main

at com.bernard.epub3.Epub3.onCreate(Epub3.java:55) 
at android.app.Activity.performCreate(Activity.java:5458) 

ich die .jar integrieren verwaltet: sie im libs Ordner sind und meine build.gradle sieht enthält die folgenden Referenz

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 23 
buildToolsVersion "23.0.2" 

defaultConfig { 
    applicationId "com.bernard.epub3" 
    minSdkVersion 19 
    targetSdkVersion 23 
    versionCode 1 
    versionName "1.0" 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 

} 

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
compile files ('libs/epublib-core-latest.jar') 
compile files ('libs/slf4j-android-1.5.8-sources.jar') 
compile 'com.android.support:appcompat-v7:23.4.0' 
} 

und mein Haupt-Java sieht wie folgt aus:

package com.bernard.epub3; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import java.io.IOException; 

import java.io.InputStream; 

import java.util.List; 

import nl.siegmann.epublib.domain.Book; 

import nl.siegmann.epublib.domain.TOCReference; 

import nl.siegmann.epublib.epub.EpubReader; 

import android.app.Activity; 

import android.content.res.AssetManager; 

import android.graphics.Bitmap; 

import android.graphics.BitmapFactory; 

import android.os.Bundle; 

import android.util.Log; 

public class Epub3 extends AppCompatActivity { 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_epub3); 
    AssetManager assetManager = getAssets(); 
    try { 
     // find InputStream for book 
     InputStream epubInputStream = assetManager 
       .open("brit.epub"); 

     // Load Book from inputStream 

     Book book = (new EpubReader()).readEpub(epubInputStream); 

     // Log the book's authors 

     Log.i("epublib", "author(s): " + book.getMetadata().getAuthors()); 

     // Log the book's title 

     Log.i("epublib", "title: " + book.getTitle()); 

     // Log the book's coverimage property 

     Bitmap coverImage = BitmapFactory.decodeStream(book.getCoverImage() 
       .getInputStream()); 

     Log.i("epublib", "Coverimage is " + coverImage.getWidth() + " by " 
       + coverImage.getHeight() + " pixels"); 

     // Log the tale of contents 

     logTableOfContents(book.getTableOfContents().getTocReferences(), 0); 

    } catch (IOException e) { 

     Log.e("epublib", e.getMessage()); 

    } 

} 

/** 

* Recursively Log the Table of Contents 

* 

* @param tocReferences 

* @param depth 

*/ 

private void logTableOfContents(List<TOCReference> tocReferences, int depth) { 

    if (tocReferences == null) { 
     return; 
    } 

    for (TOCReference tocReference : tocReferences) { 
     StringBuilder tocString = new StringBuilder(); 
     for (int i = 0; i < depth; i++) { 
      tocString.append("\t"); 
     } 

     tocString.append(tocReference.getTitle()); 

     Log.i("epublib", tocString.toString()); 

     logTableOfContents(tocReference.getChildren(), depth + 1); 

    } 

} 

} 

Dank in advanc e für die Hilfe!
