Here Below showlineChart() method will be create piechart using Achartengine in Android.
In  showlineChart()  method org.achartengine.GraphicalActivity class is Responsable to create LineChart.


Android Activity(MainActivity.java)
package com.androidsurya.achartengine;

import org.achartengine.ChartFactory;
import org.achartengine.chart.PointStyle;
import org.achartengine.model.XYMultipleSeriesDataset;
import org.achartengine.model.XYSeries;
import org.achartengine.renderer.XYMultipleSeriesRenderer;
import org.achartengine.renderer.XYSeriesRenderer;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;

public class MainActivity extends Activity {

private String[] mMonth = new String[] {
"Jan", "Feb" , "Mar", "Apr", "May", "Jun",
};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        showlineChart();
    }  
    private void showlineChart(){
    int[] x = { 1,2,3,4,5};
    int[] income = { 240,467,259,570,500};
    int[] expense = {200, 521, 290, 219, 457};
   
    // Creating an  XYSeries for Income
    XYSeries incomeSeries = new XYSeries("Income");
    // Creating an  XYSeries for Income
    XYSeries expenseSeries = new XYSeries("Expenses");
    // Adding data to Income and Expense Series
    for(int i=0;i<x.length;i++){
    incomeSeries.add(x[i], income[i]);
    expenseSeries.add(x[i],expense[i]);
    }
   
    // Creating a dataset to hold each series
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    // Adding Income Series to the dataset
    dataset.addSeries(incomeSeries);
    // Adding Expense Series to dataset
    dataset.addSeries(expenseSeries);    
   
   
    // Creating XYSeriesRenderer to customize incomeSeries
    XYSeriesRenderer incomeRenderer = new XYSeriesRenderer();
    incomeRenderer.setColor(Color.WHITE);
    incomeRenderer.setPointStyle(PointStyle.CIRCLE);
    incomeRenderer.setFillPoints(true);
    incomeRenderer.setLineWidth(2);
    incomeRenderer.setDisplayChartValues(true);
   
    // Creating XYSeriesRenderer to customize expenseSeries
    XYSeriesRenderer expenseRenderer = new XYSeriesRenderer();
    expenseRenderer.setColor(Color.BLUE);
    expenseRenderer.setPointStyle(PointStyle.CIRCLE);
    expenseRenderer.setFillPoints(true);
    expenseRenderer.setLineWidth(3);
    expenseRenderer.setDisplayChartValues(true);
   
   
    // Creating a XYMultipleSeriesRenderer to customize the whole chart
    XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();
    multiRenderer.setXLabels(0);
    multiRenderer.setChartTitle("Income vs Expense Chart");
    multiRenderer.setXTitle("Year 2011");
    multiRenderer.setYTitle("Amount in Rupees");
    multiRenderer.setZoomButtonsVisible(true);        
    for(int i=0;i<x.length;i++){
    multiRenderer.addXTextLabel(i+1, mMonth[i]);    
    }    
   
    // Adding incomeRenderer and expenseRenderer to multipleRenderer
    // Note: The order of adding dataseries to dataset and renderers to multipleRenderer
    // should be same
    multiRenderer.addSeriesRenderer(incomeRenderer);
    multiRenderer.addSeriesRenderer(expenseRenderer);
   
    // Creating an intent to plot line chart using dataset and multipleRenderer
    Intent intent = ChartFactory.getLineChartIntent(getBaseContext(), dataset, multiRenderer);
   
    // Start Activity
    startActivity(intent);
   
    }
