Project Overview….

•To develop a mobile application using the Google android platform for finding the optimal route

•This application allows the user to input the multiple locations that the user is interested to visit and find the optimal route among them

•The user can give his/her own priority in visiting the locations, so the optimal route can be found in the listed priority

5

Software Requirement….

•Windows XP (32-bit) or Vista (32- or 62-bit)

•Eclipse IDE 3.5 (Galileo)

•Android SDK 2.1

•XML

8

What does the application contain?....

•Graphical User Interface (GUI )

•Algorithm

•Google Maps

Algorithm….

•Euclidean Distance Formula

•Nearest Neighbor Algorithm

11

Euclidean Distance Formula….

•Calculate distance between locations

Where,p: Current locationq: Desire locationd: distance between p & q

12

Nearest Neighbor Algorithm….

1. Stand on an arbitrary vertex as current vertex

2. Find out lightest edge connecting current

vertex and unvisited vertex V

3. Set current vertex to V

4. Mark V as visited

5. If all the vertices in domain are visited, then

terminate

6. Go to step 2

Android….

•Android is mobile phone operating system developed by Google

•Is first complete, open and free mobile platform

•100% java support

•We can create application for the android platform using the Android SDK

17

Android….

•Java and XML based GUI

•Application written using java programming language run on Dalvik, a custom virtual machine designed for embedded use, which runs on top of a Linux Kernel

Download and Install the SDK….

Download and install the SDK starter package

Select a starter package for your operating system and download it

Install the ADT Plug-in for Eclipse If you are developing in Eclipse, set up a remote update

site and install the Android Development Tools (ADT) plug-in

Add Android platforms to your SDK Use the Android SDK and AVD Manager, included in the

SDK starter package, to add one or more Android platforms

Sample Android Code….

<TextView android:id="@+id/label" android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="Zip Code:"/><EditText android:id="@+id/entry" android:layout_width="fill_parent" android:layout_height="wrap_content“ android:background="@android:drawable/editbox_background” android:layout_below="@id/label"/> <Button android:id="@+id/ok" android:layout_width="wrap_content" android:layout_height="wrap_content"

android:layout_below="@id/entry" android:layout_alignParentRight="true" android:layout_marginLeft="10px" android:text="OK" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toLeftOf="@id/ok" android:layout_alignTop="@id/ok" android:text="Cancel" />

</RelativeLayout>

File.java

package com.android.helloactivity;import android.app.Activity;import android.os.Bundle;/** * A minimal "Hello, World!" application. */public class HelloActivity extends Activity { public HelloActivity() { } /** * Called with the activity is first created. */ @Override public void onCreate(Bundle savedValues) { super.onCreate(savedValues); // Set the layout for this activity. You can find it // in res/layout/hello_activity.xml setContentView(R.layout.hello_activity); restoreValues(savedValues); } private void restoreValues(Bundle savedValues) { // TODO Auto-generated method stub }}

File.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- Demonstrates using a relative layout to create a form -->

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android” android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10px">
