libs folder.

Now Right click on the project name -> Properties -> Java Build Path -> Under Libraries tab ->
Add Jar -> click on your project name -> libs -> achartengine.jar -> OK

Now you have successfully Imported achartengine.jar file into the application.

Create the main Activity

Charttest.java

package com.example.charttest;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.widget.RelativeLayout;

public class Charttest extends Activity {

RelativeLayout LayoutToDisplayChart;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_chattest);

LayoutToDisplayChart=(RelativeLayout)findViewById(R.id.relative);

Intent achartIntent = new Chart().execute(Charttest.this,LayoutToDisplayChart);

}

}
