Could not find class GraphViewSeries

Question

I'm trying to show graphs on my App using GraphView library. The code is very simple:

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);

    }
}

This error:

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

And then this fatal exception:

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

is all that I get. Why can't it reach the classes I've already imported?

Perhaps you could try and go to Porject > Properties > Import and Export. Check the GraphView Jar file and move it up. Once this is done hit OK and clean the project then run.

add it into the libs Folder in your Project. for me it worked well. The developer actually also assumes to copy it to libs only ^^

I faced the same problem. Perhaps, it may happen that you could be using graphview-4.x.jar extension in your bulid file. You are trying to import ' GraphviewSeries ' from ' GraphView ' extension. But that would throw you a error.

Since there is a migration from GraphView 3.1 to 4.0 you need to follow the latest format or rather use graphview3.x.jar file to import GraphViewSeries.

For further understanding please refer to the following link:
