如何在Eclipse中将第三方库集成到Android

Question

I am trying to integrate Stanford POS tagger to my android application by following the tutorial at : http://new.galalaly.me/2011/05/tagging-text-with-stanford-pos-tagger-in-java-applications/

These are the steps that I followed,

1. I created a new folder called taggers and saved .taggers and .props file in there

2. I imported the library to my project by right clicking my project>Configure Build Path>Add External Jars

3. Then I wrote my code,

    package cct.mad.numbers; import edu.stanford.nlp.tagger.maxent.MaxentTagger; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class sum2 extends Activity{ MaxentTagger tagger = new MaxentTagger("taggers/left3words-wsj-0-18.tagger"); private TextView text; String sample = "This is a sample text"; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.text2); text = (TextView)findViewById(R.id.news); // The tagged string String tagged = tagger.tagString(sample); text.setText(tagged); } } 

However, it gives an error on

    MaxentTagger tagger = new MaxentTagger("taggers/left3words-wsj-0-18.tagger");

saying: "Default constructor cannot handle exception type ClassNotFoundException thrown by implicit super constructor. Must define an explicit constructor"

Also when I hover over, MaxentTagger in the above code and

  import edu.stanford.nlp.tagger.maxent.MaxentTagger;

it says: "Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found"

How should I fix this?

请先将库项目复制到工作区中，然后再尝试添加外部jar。
