Sample Flex Mobile Application
Let’s start building a simple flex mobile application for
android. Flex 4.6 lets you develop native applications for Android devices,
BlackBerry and IOS. We are taking example of android since it’s widely used
among Indian masses.
I’ll cover a simple hello word mobile application
development here and will show you how to deploy it on your android device.
Step : 1 Open New Mobile Project
Open a new Flex Mobile
Project
Give your project a name, say “HelloWorld”
and click on Next
Choose a template , here we are
using a blank “View Based Application”
for Google Android. Now click on Finish.
Step : 2 Default Project Structure
In the Package Explorer
you will see your project created with some default structure like this
Under default package resides
default main application file.
HelloWorld.mxml
xmlns:s="library://ns.adobe.com/flex/spark" firstView="views.HelloWorldHomeView"
applicationDPI="160">
The firstView contains the name of the
file to be shown first when application is executed.
Step : 3 HelloWorld Example Code
In HelloWorldHomeView.mxml
we will simply create a Label and two buttons to hide and show the Label.
HelloWorldHomeView.mxml
xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView">
<![CDATA[
protected function
btnClick_clickHandler(event:MouseEvent):void
{
lblHello.text="Hello
World"; }
protected function btnClear_clickHandler(event:MouseEvent):void
{
lblHello.text="";
}
]]>
verticalAlign="top"/>
click="btnClick_clickHandler(event)"/>
click="btnClear_clickHandler(event)"/>
Step : 4 Run on Desktop
To Run the application click Run
button or press Ctrl+F11. On first time execution the run configuration
appears.
Choose the option On Desktop
and then device name (like Samsung Galaxy Ace) and then click on Run.
OutPut :
Step : 5 Installing .apk on device
In order to create the .apk
file which will be deployed on your device we need to Export Release build
Click Next and go to Digital
Signature tab . Create your Certificate and Password by clicking on create
button. And then click on Finish.
You can now see your .apk (HelloWorld.apk)
file in Package Explorer
Now send this .apk to you device
via Data Cable or Bluetooth and install the application and Enjoy!!!
