Titanium Titanium is an open source framework for

building Native mobile applications.

Open Source (Apache 2.0).

Supported OS :iOSAndroid

Has its Own IDE with code completion & debugging* support.

Facilitates for submitting the app on Market.

Installation Guide

Requirements:

>For Android Emulator & Development 1.Sun Java Development Kit 6 (aka 1.6) 2.Android Development Kit

>For Building Titanium Mobile 1.Python 2.5/2.6 2.Scons 1.2.0.x 3.Git

Installing JAVA

Setting up the environment and path

1. Goto : Control Panel > System & Security > System > Advanced System Settings > Environment Variables.

2. Goto : Path in System Variables & Edit.

3. Add : C:\Java\jdk1.6.0_21\bin; to path.

1. Open a new command window and enter the command below. > javac -version

2. If you've configured the PATH correctly, you should see something similar to.

Verify Java Install

3. This means our JAVA is installed correctly.

Installing the Android Development Kit (ADK)

1.Launch the installer_r09-windows setup.

2.Rename the destination folder as C:\android-sdk.

3.Start the SDK manager.4.Cancel the Installation of packages.5.Copy and replace the platforms, platform-tools, extras, temp folders from DVD to C:/android-sdk.6. Click Refresh in the Installed Packages option of AVD Manager. You will see something like this

7.Add the ADK to the PATH 1. Add : C:\android-sdk\tools;C:\android-sdk\platforms\android-4\tools; before the JAVA path.

8.Workaround for a missing adb

Due to a recent change in the Android SDK file structure, Titanium Developer expects the adb.exe executable to be in path\to\android-sdk-windows\tools whereas it currently resides in path\to\android-sdk-windows\platform-tools.

To resolve this issue: >Simply copy adb.exe and AdbWinApi.dll from platform-tools to the tools directory.

NOTE: Remember to repeat this process with adb each time Google updates the Platform-Tools package, or Android SDK itself.

Verify ADK Install

1. Open a new command window and enter the commands below. > aapt v > android list2. If you've configured everything correctly, you should see something similar to.

Lets run our first app on emulator

1.Goto: File>New>Titanium Mobile Project2.Fill the Details of the App & click Finish.

Run the code.After the Studio displays : Deployed hello ... Application should be running. You will see something like this in the emulator

The Application Project Structure

• Build .apk

• Resourcesapp.jsSplash ScreenApplication Icon

• Tiapp.xml

Titanium follows MVC : Model-View-Controller

The Titanium Architecture

How does Titanium work ?

• Pre-compiler

• Front-end compiler

• Platform compiler & packager

Titanium Design Concepts

The following are the major design components in Titanium:

• Windows - windows host one or most Views

• Views - views draw content on the screen

• Widgets - widgets are special types of views that perform specific actions like buttons

Self-contained Windows

For example, to create a simple Window, you could do the following:

var win = Ti.UI.createWindow(); >>Window is similar to page of HTML

var view = Ti.UI.createView({ >>One window can have many viewsbackgroundColor:'red',width:200,height:150,top:150});

win.add(view); >> Add view to the window.

win.open(); >> Open the window.

var view2 = Ti.UI.createView({backgroundColor:'red',width:50,height:50,bottom:50});

win.add(view2);

Create a new View for animation

For Alert:

view.addEventListener(‘click',function() { alert(‘You clicked Upper View’); });

Adding interactivity

view2.addEventListener(‘dbclick',function() { view2.animate({

width:150,height:150,duration:1000});

});

For Animation

Labels

Text to be displayed on screen

var mylabel = Titanium.UI.createLabel({ text: 'Wow! This is a Label', height:'auto', width:'auto', color:'#900', font:{fontSize:20}, textAlign:'center', top: 10});

Text Fields

Text to be entered within a field

var tf1 = Titanium.UI.createTextField({ hintText: 'You Name Here', height:35, top:40, left:10, width:250}); tf1.addEventListener('blur',function(e){ //if focus moved away from tf1

alert('Welcome ' + tf1.value);});

Button

Add your own buttons and functions

var button = Titanium.UI.createButton({ //create Button title: 'Hello !', width: 100});

win.add(button);

button.addEventListener('click',function(e) //if button is clicked{ alert("You just clicked the button"); //display alert message});

Picker

Add Picker which functions as drop-down box

var picker = Titanium.UI.createPicker();var data = [];data[0]=Titanium.UI.createPickerRow({title:'Bananas'});data[1]=Titanium.UI.createPickerRow({title:'Strawberries'});data[2]=Titanium.UI.createPickerRow({title:'Mangoes'});data[3]=Titanium.UI.createPickerRow({title:'Grapes'}); picker.add(data);win.add(picker); picker.addEventListener('change',function(e){ //if picker is changed

alert('You selected '+e.row);});

Activity Indicator

Display this if some Activity is to be performed in background

var actInd = Titanium.UI.createActivityIndicator({ //activity indicator height:50, width:10, message: 'You cannot do anything now'});

actInd.show();

Animations

We can add Animations to any widgets

var animation = Titanium.UI.createAnimation({ //define animationheight:100,duration:1000,repeat:5,autoreverse:true

});

Object.animate(animation); //start animation

ImageView

Eg: ImageView from Titanium API

var myimage = Ti.UI.createImageView({ image: 'android/appicon.png', width:128, height:128, borderColor:'#aaa', borderRadius:10, borderWidth:5});

Adding interactivity to ImageView

myimage.addEventListener('touchend',function(e) { myimage.animate({

width:128,height:128,duration:500});

});

myimage.addEventListener('touchstart',function(e) { myimage.animate({

width:200,height:200,duration:500});

});

On Touch Start:

On Touch End:

Table View

Creation of static or dynamic Tables

var data = [{title:"Row 1"},{title:"Row 2"}];data.push({title:'Row 3'}); var table = Titanium.UI.createTableView({ //static creation of table

data:data,backgroundColor: 'blue',rowHeight: 20,separatorColor: 'red'

}); table.appendRow({title:'Row 4'}); //dynamically add rows to table table.addEventListener('click',function(e){

alert(e.rowData.title);});
