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 5

Basic System Architecture…. Figure 1. Basic Architecture Diagram 6

Use Case…. Android mobile application for TSP Figure 2. Application overview use case diagram 7

What does the application contain? . . • Graphical User Interface (GUI ) • Algorithm • Google Maps 8

Graphic User Interface…. Android mobile application for TSP Figure 3. GUI for the android mobile application 9

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 12

Project Timeline…. 15

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 17

Android Architecture…. Figure 6. Android Architecture 18

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 Hello. Activity extends Activity { public Hello. Activity() { } /** * Called with the activity is first created. */ @Override public void on. Create(Bundle saved. Values) { super. on. Create(saved. Values); // Set the layout for this activity. You can find it // in res/layout/hello_activity. xml set. Content. View(R. layout. hello_activity); restore. Values(saved. Values); } private void restore. Values(Bundle saved. Values) { // TODO Autogenerated method stub }} File. xml <? xml version="1. 0" encoding="utf-8"? > <!-- Demonstrates using a relative layout to create a form --> <Relative. Layout xmlns: android="http: //schemas. android. com /apk/res/android” android: layout_width="fill_parent" android: layout_height="wrap_content" android: padding="10 px"> <Text.
