我正在使用Lucene爲詞幹。我在一個Java應用程序（主要）上進行了測試，並且工作完美。但是，在我的android應用程序（在onCreate）它不起作用。有誰知道爲什麼？ 這是我在的onCreate代碼，在主要和錯誤時，它的onCreate旋轉：在android應用程序中的PorterStemmer錯誤
import org.tartarus.snowball.ext.PorterStemmer;
import com.veryinteligent.jarvas.R;
import android.app.Activity;
import android.os.Bundle;
public class LuceneStemmer extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.wordcommands);
String term = "obviously";
PorterStemmer stemmer = new PorterStemmer();
stemmer.setCurrent(term);
stemmer.stem();
System.out.println(stemmer.getCurrent());
}
}
import org.apache.lucene.analysis.en.EnglishAnalyzer;
import org.apache.lucene.queryparser.classic.ParseException;
import org.apache.lucene.queryparser.classic.QueryParser;
import org.tartarus.snowball.ext.PorterStemmer;
import org.tartarus.snowball.ext.PortugueseStemmer;
import com.rmtheis.yandtran.language.Language;
import com.rmtheis.yandtran.translate.Translate;
public class TranslationTester {
public static void main(String[] args) {
String term = "Obviously";
PorterStemmer stemmer = new PorterStemmer();
stemmer.setCurrent(term);
stemmer.stem();
System.out.println(stemmer.getCurrent());
}
}
這是在運行時遇到的堆棧跟蹤。

[更新]我發現我必須通過放置libs文件夾來導入我的文件。問題是我有一個錯誤「轉換爲達爾文格式失敗，錯誤1」。這是我的控制檯消息：
