找不到類GraphViewSeries

我試圖使用GraphView庫在我的應用程序上顯示圖形。該代碼非常簡單：找不到類GraphViewSeries

package pizio.prova.it; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.LinearLayout; 

import com.jjoe64.graphview.GraphView; 
import com.jjoe64.graphview.GraphView.GraphViewData; 
import com.jjoe64.graphview.GraphView.GraphViewSeries; 
import com.jjoe64.graphview.LineGraphView; 

public class ProvaGraphViewActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 


     // init example series data 
     GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] { 
       new GraphViewData(1, 2.0d) 
       , new GraphViewData(2, 1.5d) 
       , new GraphViewData(3, 2.5d) 
       , new GraphViewData(4, 1.0d) 
     }); 


     GraphView graphView = new LineGraphView( 
       this // context 
       , "GraphViewDemo" // heading 
     ); 
     graphView.addSeries(exampleSeries); // data 

     LinearLayout layout = (LinearLayout) findViewById(R.id.graphLayout); 
     layout.addView(graphView); 

    } 
}

此錯誤：

E/dalvikvm(1224): Could not find class 'com.jjoe64.graphview.GraphView   $GraphViewSeries', referenced from method pizio.prova.it.ProvaGraphViewActivity.onCreate

然後這個致命異常：

java.lang.NoClassDefFoundError: com.jjoe64.graphview.GraphView$GraphViewSeries 
E/AndroidRuntime(1224):  at pizio.prova.it.ProvaGraphViewActivity.onCreate(ProvaGraphViewActivity.java:22)

是一切，我得到的。爲什麼它不能達到我已經導入的課程？
