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
4
Software Requirement….
•Windows XP (32-bit) or Vista (32- or 62-bit)
•Eclipse IDE 3.5 (Galileo)
•Android SDK 2.1
•XML

What does the application contain?....
•Graphical User Interface (GUI )
•Algorithm
•Google Maps

Algorithm….
•Euclidean Distance Formula
•Nearest Neighbor Algorithm
10
Euclidean Distance Formula….
•Calculate distance between locations
Where,
p: Current location
q: Desire location
d: distance between p & q
11
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
16
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) plugin
 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
19
Sample Android Code….

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 Autogenerated 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">
