I am trying to create a Dial Chart using AChartLibrary(I am completely lost..I have no idea how to do it and I am trying my hand in it but to no avail so any tutorial that might help is welcomed).
I have managed to implement the Chart as follows
import android.app.Fragment;
import android.graphics.Color;
import android.os.Bundle;
import android.view.ViewGroup;
import android.view.View;
import android.view.LayoutInflater;
import android.widget.GridLayout;
import android.widget.LinearLayout;
import org.achartengine.GraphicalView;
import org.achartengine.model.CategorySeries;
import org.achartengine.ChartFactory;
import org.achartengine.renderer.DefaultRenderer;
import org.achartengine.renderer.DialRenderer;
import org.achartengine.renderer.DialRenderer.Type;
import org.achartengine.renderer.SimpleSeriesRenderer;
public class Fragment_Statistics extends Fragment {
private GraphicalView mChartView;
public double MAX=180.00,MIN=0.00;
public View onCreateView(LayoutInflater layoutInflater,ViewGroup container,Bundle SavedInstances){
View statistics_fragment=getActivity().getLayoutInflater().inflate(R.layout.fragment_statistics, null);
/** Colors to be used for the pie slices. */
int[] COLORS = new int[] { Color.GREEN, Color.BLUE, Color.MAGENTA, Color.CYAN };
/** The main series that will include all the data. */
CategorySeries mSeries = new CategorySeries("Dial Chart");
mSeries.add(MAX);
/** The main renderer for the main dataset. */
DialRenderer mRenderer = new DialRenderer();
mRenderer.setAngleMin(MIN);
mRenderer.setAngleMax(MAX);
mRenderer.setMaxValue(MAX);
mChartView=ChartFactory.getDialChartView(getActivity(),mSeries,mRenderer);
return statistics_fragment;
}
Whenever I execute it I get the following error
java.lang.NoClassDefFoundError: org.achartengine.model.CategorySeries

The error points to CategorySeries line and as you can see I have imported the necessary files but still it is showing an error.
This question also deals with a similar situation but the solution is provided for eclipse not for android studio. The answers in the aforementioned posts seem to suggest that the problem lies in the gradle file but my file seems to be correct
GRADLE:
apply plugin: 'com.android.application'

}
What is causing this error and how can I rectify it? Any and all help is appreciated..
