Flex 4.6 and SplitViewNavigator in AIR : Demo application – Finnkino Movies

Adobe Flex 4.6 includes several new and updated mobile-optimized Spark components (for example SplitViewNavigator, CallOutButton, SpinnerList, DateSpinner, Text Enhancements and ToggleSwitch).

In this example I used SplitViewNavigator to show Finnkino‘s Theatres in the first view of the SplitViewNavigator. Second view shows the selected Theatre’s movies (what are running at this day) or all movies that are running in Finnkino’s Theatres.

<s:SplitViewNavigator id="splitNavigator" width="100%" height="100%" autoHideFirstViewNavigator="true">
<s:ViewNavigator id="areasView" width="200" height="100%" firstView="views.AreaCategory"/>
<s:ViewNavigator id="detailView" width="100%" height="100%" firstView="views.MoviesTileView">
<s:Button id="navigatorButton" label="Valitse Teatteri"

Movies in Landscape mode

SplitViewNavigator is working very nicely and it hide’s the first view in navigator when tablet is rotated to Portrait. You should add resize event handling to your application and use states in ActionContent in ViewNavigator.

<s:Application resize="resizeHandler(event);">
protected function resizeHandler(event:ResizeEvent):void {
currentState = aspectRatio;
<s:State name="portrait"/>
<s:State name="landscape"/>

Movies in Portrait mode

List and ItemRenderers
I have used List to show all the movie items and own made ItemRenderer to display some basic information (or just movie image when all the movies are selected from the main list).

<s:List id="moviesList"
width="100%" height="100%"
<s:TileLayout id="tileList"
paddingLeft="5" paddingRight="5" paddingTop="5" paddingBottom="5" horizontalGap="5" verticalGap="5"
// MovieAreaTile
<s:Image source="{data.Images.EventSmallImagePortrait}" />
<s:Label id="title" styleName="title" text="{data.Title}" />
<s:Label id="startTime" styleName="data" text="{data.dttmShowStart}" />
<s:Label id="length" styleName="data" text="{data.LengthInMinutes} min" />
<s:Label id="theatre" styleName="data" text="{data.TheatreAndAuditorium}" />
<s:Label id="genre" styleName="data" text="{data.Genres}" />

All the Movies in Finnkino’s Theatres

SQLite: Automatically display same Theatre which was used in previous time
In this example I store theatreID and theatreName to SQLite database every time when a new Theatre is selected. Those values are used when application is started again.

Connection to database:

private function connect(type:Number):void {
dbConn = new SQLConnection();
if (type == CREATE_DB) dbConn.addEventListener(SQLEvent.OPEN, createTable);
else dbConn.addEventListener(SQLEvent.OPEN, getTheatreData);
dbConn.addEventListener(SQLErrorEvent.ERROR, errorHandler);

Create a table:

private function createTable(event:SQLEvent):void {
var dbStatement:SQLStatement = new SQLStatement();
dbStatement.sqlConnection = dbConn;
dbStatement.addEventListener(SQLEvent.RESULT, theatreTableCreated);
dbStatement.addEventListener(SQLErrorEvent.ERROR, errorHandler);
dbStatement.text = "CREATE TABLE IF NOT EXISTS movieTable (id INTEGER PRIMARY KEY AUTOINCREMENT, theatreID TEXT, theatreName TEXT);";

Table is created a first time -> add some sample data to table

private function theatreTableCreated(event:SQLEvent):void {
var dbStatement:SQLStatement = new SQLStatement();
dbStatement.sqlConnection = dbConn;
// just set default data when table is created
theatreID = 1015;
theatreName = "Jyväskylä";
dbStatement.text = "INSERT INTO movieTable (theatreID, theatreName) VALUES(‘"+theatreID+"’,’"+theatreName+"’);";

Theatre (id and name) data is added first time, load events with HTTPService

<s:HTTPService id="finnkinoArea" showBusyCursor="true" url="{url}"

private function theatreDataAdded(event:SQLEvent):void {

private function getTheatreData(event:SQLEvent):void {
var dbStatement:SQLStatement = new SQLStatement();
dbStatement.sqlConnection = dbConn;
dbStatement.text = "SELECT theatreID, theatreName FROM movieTable where id=1";

TheatreID and name is loaded from SQLite, start loading XML data from Finnkino’s service

private function theatreResult(event:SQLEvent):void {
var dbResult:SQLResult = SQLStatement(;
theatreID =[0].theatreID;
theatreName =[0].theatreName;
// load previous used theatre
public function loadEvents(theatreID:uint):void {
// one Teatre
if (theatreID != -1) url = urlBase + theatreID;
// all events from Finnkino
else url = "";
// call HTTPService

Movie Details
Movie details are shown when user clicks MovieTile from TileView. Finnkino’s Service offers a lot of information about the movie. In this example I only display some sample data and movie trailer. Movie trailer can be played in fullscreen mode too (use this only in Landscape – there a some issues in portrait mode – in this example :-)

<s:Scroller width="100%" height="100%">
<s:VGroup width="100%">
<s:Image source="{data.Images.EventLargeImagePortrait}" />
<s:Label text="{data.Title} ({data.OriginalTitle})" styleName="title"/>
<s:Label text="{data.RatingLabel}" styleName="data" />
<s:Label id="startTime" styleName="data" text="{data.dttmShowStart}" />
<s:Label id="length" styleName="data" text="{data.LengthInMinutes} min" />
<s:Label id="genre" styleName="data" text="{data.Genres}" />
<s:Label id="showUrl" styleName="dataBlue" text="{data.ShowURL} – (osta liput)" click="showUrl_clickHandler(event)" />
<s:Label id="eventUrl" styleName="dataBlue" text="{data.EventURL} – (lisätietoa elokuvasta)" click="eventUrl_clickHandler(event)" />
<s:Label text="{movieData.Synopsis}" width="100%" styleName="synopsis" />
<s:VideoPlayer id="myVideo" source="{movieData.Videos.EventVideo.Location}" autoPlay="false" visible="{isVideo}" width="{this.width-20}"/>
<s:Button label="Takaisin" id="takaisin" click="takaisin_clickHandler(event)"/>

Source codes

There are a few bugs in this example (too). Sometimes the date is missing from first views, and VideoPlayer is messing up if it is in fullscreen mode in Landscape and you turn the device to portrait.. but now it is working for my purposes :-) and finally I have only tested this in Samsung Galaxy Tab 10.1 not in mobile…

This example uses Finnkino’s Services

Developing AIR application to run in different screen sizes

A few days ago I got Samsung Galaxy S 2 and Tab 10.1 in my hands and I want to test how to make an AIR application that runs in both of these (with different screen sizes). This demo application uses SQLite database to collect information about Interesting Places (place information and picture).

I decided to make mobile application with s:Application and first test is application running in mobile or tablet. After that different states are used in s:ViewNavigator to launch MainPhoneView or MainTabletView view depending on used device (mobile or tablet). (Michael Chaize has wrote excellent article about Adaptive UI: Mobile vs. Tablet).

left="0" top="0"
right="0" bottom="0"
firstView="views.MainPhoneView" firstView.tablet="views.MainTabletView"
resize="mainNavigator.scrollRect = new Rectangle(0, 0, mainNavigator.width, mainNavigator.height)">

draws PlaceList component (which is used in the left side of MainTabletView view also) which displays some already embeded Interesting Places from SQLite database (title and time) by default. PlaceView is opened when users clicks PlaceList item and place information data is show with PlaceComp component (which is used in the right side of MainTabletView view also). Sample SQLite database is embeded into Flex Project.

<comps:PlacesList id="placesList"
width="100%" height="100%"


MainTabletView holds Placelist and PlaceComp components in a same view in tablet. So there are not View changes in tablet version of this application. All needed information can be show in one View.

<s:HGroup width="100%" height="100%">
<comps:PlacesList id="placesList" places="{data}"
width="33%" height="100%" click="placesList_clickHandler(event)">
<comps:PlaceComp id="place" width="67%">

Add Place

User can write some lines from interesting place and take one picture. All of these information are saved into SQLite database. Same component are used in mobile and tablet view.

Using your own made components in different views helps application development into different screen sizes. This is working quite a nicely in AIR development. Like in this small example same components are used in Tablet and Mobile views to build this example.


There are a few bugs and limitations in this example.. I did this just for a testing purposes :-)

Send pictures from Android device to Windows with AIR applications

In this example I will show how you can take and send pictures from Android phone to Windows application using Adobe AIR in Android and Windows.

Create AIR for Android application (to take and send picture)

In Adobe AIR 2.5 there is Camera UI class that allows you to capture a still image or video using the default camera application on a device. First check that Camera is supported and create a new Camera UI object and register MediaEvent.COMPLETE to call onComplete function when picture is taken.

After that establish a new NetConnection for P2P in the local network (LAN). This can be done by specifying connection string as “rtmpf:” in NetConnection.

private function init():void {
if (CameraUI.isSupported){
myCam = new CameraUI();
myCam.addEventListener(MediaEvent.COMPLETE, onComplete);
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);

When connection is made netStatus function will be called. If NetConnection is ok it is time to setup own group for multicasting. You can set up your own NetGroup with GroupSpecifier. Enable local connections between peers and set your IP address and port for multicasting. You can find more details about multitasking for example here: (Tom Krcha – thanks about your excellent demos and work with Flash based Technologies).

private function netStatus(event:NetStatusEvent):void {
switch( {
case "NetConnection.Connect.Success":
var groupspec:GroupSpecifier = new GroupSpecifier("fi.ptm.imageApp/myChannel");
groupspec.postingEnabled = true;
groupspec.ipMulticastMemberUpdatesEnabled = true;
group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());
group.addEventListener(NetStatusEvent.NET_STATUS, netStatus);

A new picture is taken when user presses Take Picture Button in device’s screen. Picture is taken with Android Native Camera Application (using with Camera UI class) and onComplete will be called when picture is taken.

In this example image is shown with <mx:Image id=”image”> and image URL is used when image is sent to Windows AIR application.

private function takePicture():void {
image.filters = [];
if (CameraUI.isSupported) myCam.launch(MediaType.IMAGE);

private function onComplete(evt:MediaEvent):void{
image.source =;
imageURL =;

Image is converted to ByteArray and all of those bytes is sent to Windows AIR application when user clicks send button in the devices screen.

private function sendPicture():void {
var fs:FileStream = new FileStream(); File(imageURL), FileMode.READ);
var bytes:ByteArray = new ByteArray();
if (bytes == null) {
trace("Image bytes is null!");
} else {
// create a new object with image data and image count (sent)
var message:Object = new Object();
message.bytes = bytes;
message.images = ++imagesSent;;
trace("Pictures sent:"+imagesSent);

Create AIR local client in Windows (receive images)

Windows AIR application is connected to same group and it is waiting for images from AIR for Android application. If we get a new netStatus with NetGroup.Posting.Notify message then a new image is received from Android. First new Sprite is created and all of those image bytes is loaded with Loader.

public function receivePicture(message:Object):void {
imageContainer = new Sprite();
var loaderContext:LoaderContext = new LoaderContext();
loaderContext.allowCodeImport = false;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onPicLoaded,false,0,true);
loader.loadBytes(message.bytes, loaderContext);
// add a new sprite to hold image
imageSprite = new Sprite();

ImageSprite is a wrapped for a new image sprite to get Parallel image animation into it (scaling, positioning and sizing) for 4 seconds.

private function onPicLoaded(e:Event):void {
imageSprite.x = -imageContainer.width / 2;
imageSprite.y = -imageContainer.height / 2;
imageContainer.x += imageContainer.width / 2;
imageContainer.y += imageContainer.height / 2;
startX = imageContainer.width / 2;
startY = imageContainer.height / 2;
targetX = Math.floor(Math.random()*frame.width);
var borderSize:uint = 100;
if (targetX < borderSize) targetX = borderSize;
if (targetX > (frame.width-borderSize)) targetX = frame.width – borderSize;
targetY = Math.floor(Math.random()*frame.height);
if (targetY < borderSize) targetY = borderSize;
if (targetY > (frame.height-borderSize)) targetY = frame.height – borderSize;
startRotation = Math.floor(Math.random()*360);
if (Math.random() > .5) targetRotation = startRotation + 180;
else targetRotation = startRotation – 180;;

Here is a basic parallel animation used to make a cool sliding effect with a new images. All previous taken images will be visible there too.

<mx:Parallel id="imageAnimation" target="{imageContainer}" >
<mx:AnimateProperty property="scaleX" fromValue="1" toValue="0.2" duration="4000" />
<mx:AnimateProperty property="scaleY" fromValue="1" toValue="0.2" duration="4000" />
<mx:AnimateProperty property="x" fromValue="{startX}" toValue="{targetX}" duration="4000" />
<mx:AnimateProperty property="y" fromValue="{startY}" toValue="{targetY}" duration="4000" />
<mx:AnimateProperty property="rotation" fromValue="{startRotation}" toValue="{targetRotation}" duration="4000" />

Testing and source codes

You have to install Flex 4.1 (or newer) and AIR 2.5 SDK to try these examples (just copy/overwrite AIR SDK 2.5 to Flash Builder sdks/4.1.0 folder, or make copy from 4.1.0 to for example FlexAIR2.5 folder and overwrite there).

Image Gallery with Flex, PHP and MySQL

There are many Image Galleries available on web, but time to time I want to make one of me own. This time I used Flex, PHP and MySQL. I found one excellent Flex Component from Doug McCuneCoverFlow Component and created my Image Gallery Menu with it.

Image Gallery Menu

Selected gallery is displayed with own state in Flex, thumbnails and image information are displayed in bottom of the screen.

Image Gallery Pictures

New galleries can be uploaded to server with Admin tool. Admin tool sends gallery information to PHP which adds gallery information to MySQL table. After gallery is initialized, all selected pictures will be send to server and thumbnails will be generated with PHP.

Image Gallery Admin

Here are sources and installation instructions:

1. MySQL tables
– create following tables
– if you change table names, edit PHP-files also

mysql> describe ptm_imagegallery;
| Field       | Type         | Null | Key | Default | Extra          |
| gallery_ID  | int(11)      | NO   | PRI | NULL    | auto_increment |
| name        | varchar(50)  | YES  |     | NULL    |                |
| description | varchar(100) | YES  |     | NULL    |                |
| date        | date         | YES  |     | NULL    |                |
| password    | varchar(45)  | NO   |     |         |                |
| count       | int(11)      | YES  |     | NULL    |                |
| size        | int(11)      | YES  |     | NULL    |                |

mysql> describe ptm_imagegalleryimages;
| Field      | Type        | Null | Key | Default | Extra          |
| image_ID   | int(11)     | NO   | PRI | NULL    | auto_increment |
| gallery_ID | int(11)     | YES  |     | NULL    |                |
| filename   | varchar(30) | YES  |     | NULL    |                |
| date       | date        | YES  |     | NULL    |                |
| width      | int(11)     | YES  |     | NULL    |                |
| height     | int(11)     | YES  |     | NULL    |                |
| views      | int(11)     | YES  |     | NULL    |                |

2. PHP files
– copy PHP files to your server and edit needed MySQL variables

3. Flex project
– edit and compile Flex sources, use your own domain and path’s

Racing Golf Tour – Flash Lite, Flex 2, PHP, MySQL – Example, Tutorial

My friends and I play golf in summer times and we have one major tournament at the end of July yearly. We drive then around Finland one week and play about 18-36 holes in each day. We needed a system what stores our golf scorecards and maybe gives somekind of analyse of playing. So I decided to do a application for that purpose. Now here is Flex application to test and of course all Flex sources are available to you also. Forum Nokia will release Flash Lite part of this application soon in early 2008, maybe in January, so you can download Flash Lite sources from there then.

Flash Lite application can send players scorecards data to server and get basic analyses from server side (like scores, pbs, firs, girs, birdies and so on). Here is a few screenshots from Flash Lite application:

Flex 2 application is web based client to this application – there player can add, edit and delete scorecards and get beautiful graphics. This Flex application uses AMFPHP 1.9 at the backend of this applications. There are a lot of data in screen so you should have at least 1024×768 screen resolution to test this application.

You can test this Flex application here: Racing Tour Golf (login: guest, passwd: guest). There are now only testing material available in my player name, all other players data are empty.

Here are Flex, PHP, MySQL source codes of this application:

AMFPHP Racing Golf Tour Services
MySQL Racing Golf Tour Tables
Flex Racing Golf Tour Sources

Merry Christmas and a Happy New Year to everyone!
