根据此链接，我已完成以下步骤。
Slf4j-安卓。你可以在http://www.slf4j.org/android/
下载这个
入门
从https://github.com/downloads/psiegman/epublib/epublib-core-latest.jar
下载 epublib-core-latest.jar 下载 slf4j-android
将两者都添加到您的 android 项目中
完整的电子书阅读器和源代码。
我正在使用 Eclipse SDK 版本：3.7.2。
我在运行时收到此错误：java.lang.NoClassDefFoundError: nl.siegmann.epublib.epub.EpubReader。
我使用了下面提到的代码
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;
/**
* Log the info of 'assets/books/testbook.epub'.
*
* @author paul.siegmann

*/
public class LogTestBookInfo extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AssetManager assetManager = getAssets();
try {
// find InputStream for book
InputStream epubInputStream = assetManager
.open("books/testbook.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);
}
}
}
请给我一些解决方案。
