Leonardo França » Nokia http://www.leonardofranca.com Flash Platform Consultant and Developer (Adobe AIR/Flex/Flash/Flash Media Server/PHP/Java/.NET) Wed, 01 Feb 2012 14:05:46 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 Building Applications with Web RunTime(WRT) and Flash Lite for Nokia devices http://www.leonardofranca.com/index.php/2010/10/28/building-applications-with-web-runtimewrt-and-flash-lite-for-nokia-devices/ http://www.leonardofranca.com/index.php/2010/10/28/building-applications-with-web-runtimewrt-and-flash-lite-for-nokia-devices/#comments Thu, 28 Oct 2010 04:17:07 +0000 Leonardo França http://www.leonardofranca.com/?p=848 Continue reading →]]> Web RunTimeis one of the possibilities that Nokia provides for creating applications for mobile devices. If you're a web developer, you do not need much of anything else to start developing for Nokia devices using the WRT. It allows you to create widgets for S60 platform is a browser extension allowing you to Webkit browser instances to run as if they were separate applications. And you can still create rich applications using Flash.
Development Tools.
Nokia offers some tools to facilitate development to WRT:

It also provides UI Framework and Library as:

And there are some API's to work with the resources of mobile devices.

  • Platform Service 2.0 - An API in ActionScript 2.0 and JavaScript to access resources of mobile devices such as accelerometers, etc. geolocation.
  • API Bridge - is a component for Nokia devices with Symbian, which allows WRT widgets content, Adobe Flash Lite and Java applications to access device features through a plug-in architecture. Developers can extend the component APIBridge with their own plug-ins.

How does the widgets made with Web RunTime? widgets that are files with extension .wgz which is nothing but a compressed file with the files from your site. Files that are can not miss:

  • Info.plist - file responsible for the information of your widget as version, homepage, name etc.
  • index.html - in fact, can be any name that is set in the Info.plist as MainHTML.

Create widgets to WRT and Flash Lite
How do you use html to create your widgets with WRT, nothing prevents to use Adobe Flash in the same way as you use normally through the html. Let's see an example using JavaScript to communicate with Flash through the ExternalInterface class. In this example I will use the Nokia Web Developer Environment Standalone.

  • Create a new project of type web apps Symbian-> Basic web app project. Give a name for your project and click next. Basic files are generated for your project.

We will choose the User option to play two videos. We start with the html containing the video options

PLAIN TEXT
XML:
  1. <label for="select"></label>
  2.             <select name="select" id="select">
  3.               <option value="sample">sample.flv</option>
  4.               <option value="sneeze">sneeze.flv</option>
  5.             </select>
  6.             <input type="button" name="button" id="button" value="Tocar" onclick="javascript:playVideo();" />

And the html that loads the swf responsible for playing the video:

PLAIN TEXT
XML:
  1. <object id="playerFlashLite" name="playerFlashLite" width="360" height="360" data="PlayerFlashLite.swf"
  2.              allowscriptaccess='always'
  3.              allowFullScreen='true'
  4.              usefullscreen='true'
  5.              type='application/x-shockwave-flash'
  6.              loop='false'>
  7.             </object>

Edit the file basic.js to add the method that will send the video to the swf to be played.

PLAIN TEXT
JAVASCRIPT:
  1. function playVideo()
  2.       {
  3.           document.getElementById("playerFlashLite").playVideo(document.getElementById("select").value);
  4.       }

In Flash, create a file type of Flash Lite 3.0 or 3.1. In the library panel, click on the "new video". Give the name of instance "vd." In type let selecting "Video (ActionScript-controlled) and add the stage. Add the following code to run Flash video streamed from Flash Media Server:

PLAIN TEXT
ACTIONSCRIPT:
  1. import flash.external.*;
  2.  
  3.       ExternalInterface.addCallback("playVideo",this,playVideo);
  4.        
  5.       trace("init..");
  6.       var nc = new NetConnection();
  7.       nc.connect("rtmp://localhost/videoondemand");
  8.        
  9.       nc.onStatus = function(info)
  10.       {
  11.           trace("Level: " + info.level + " Code: " + info.code);
  12.       };
  13.        
  14.       function playVideo(video:String)
  15.       {
  16.           ns = new NetStream(nc);
  17.           vd.attachVideo(ns);
  18.           ns.play(video);
  19.           ns.connect();
  20.           txt.text = video;
  21.           ns.onStatus = function(info)
  22.           {
  23.               trace("Level: " + info.level + " Code: " + info.code);
  24.           };
  25.       }

We use static class ExternalInterface that our method within Flash can be called from JavaScript.. Running the emulator from Nokia Web Developer, we have something like this:

Besides the Nokia N8, we also have a Nokia C7 and Nokia E7, all running the Symbian^3 and Adobe Flash Lite 4.0 is already installed. This implies the possibility of developing applications for Symbian^3 using ActionScript 3.0 running on the browser or standalone.
We must look to the fact that Flash Lite 4.0 is not the Flash Player 10.1, they have some significant differences:

  • Flash Lite supports some features partially.
  • Flash Lite adds some features to work specifically with mobile devices.

Flash Lite 4.0 is based on Flash Player 10, having features that were introduced in Flash Player 9 and 10. Among the resources available are:

  • Multi-touch support
  • Flash Player 10 text engine
  • Using inline text input
  • RTMP data channel
  • RTMPE
  • RTMPT and RTMPTE
  • Multi bit-rate streaming
  • Geolocation
  • Accelerometer
  • SharedObject Remote(yessss! :D )

Also see partially supported classes and the Unsupported classes.
Come to our first example using the new capabilities of Flash Lite 4.0, in which case the accelerometer.

  • Create a file of type Flash Lite 4.0 in Flash CS5 or in Adobe Device Central CS5.
  • Add three dynamic text fields in them will show the coordinates of x, y and z.

We begin our coding, we have a method to create a ball that will suffer the effects of the accelerometer

PLAIN TEXT
ACTIONSCRIPT3:
  1. function createBall():void
  2.       {
  3.           ball = new Sprite();
  4.           ball.graphics.beginFill(0xFF0000);
  5.           ball.graphics.drawCircle(0, 0, RADIUS);
  6.           ball.cacheAsBitmap = true;
  7.           ball.x = stage.stageWidth / 2;
  8.           ball.y = stage.stageHeight / 2;
  9.           addChild(ball);
  10.       }

Then check if the device has an accelerometer to add the listeners that handle the sensor data and update the positions of the ball.

PLAIN TEXT
ACTIONSCRIPT3:
  1. function AccelerometerTest()
  2.       {
  3.           stage.scaleMode = StageScaleMode.NO_SCALE;
  4.           stage.align = StageAlign.TOP_LEFT;
  5.        
  6.           createBall();
  7.        
  8.           if (Accelerometer.isSupported)
  9.           {
  10.               accelerometer = new Accelerometer();
  11.               accelerometer.addEventListener(AccelerometerEvent.UPDATE, accUpdateHandler);
  12.               stage.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
  13.           }
  14.       }

And the rest of the code.

PLAIN TEXT
ACTIONSCRIPT3:
  1. function enterFrameHandler(event:Event):void
  2.       {
  3.           event.stopPropagation();
  4.           moveBall();

  9.           var newY:Number = ball.y + ySpeed;
  10.           if (newX <20)
  11.           {
  12.               ball.x = RADIUS;

  19.           }
  20.           else
  21.           {
  22.               ball.x +=  xSpeed;
  23.           }
  24.        
  25.           if (newY <RADIUS)
  26.           {
  27.               ball.y = RADIUS;
  28.               ySpeed = 0;
  29.           }
  30.           else if (newY> stage.stageHeight - RADIUS)
  31.           {
  32.               ball.y = stage.stageHeight - RADIUS;
  33.               ySpeed = 0;
  34.           }
  35.           else
  36.           {
  37.               ball.y +=  ySpeed;
  38.           }
  39.       }
  40.        
  41.       function accUpdateHandler(event:AccelerometerEvent):void
  42.       {
  43.           xSpeed +=  event.accelerationX * 2;
  44.           ySpeed -=  event.accelerationY * 2;
  45.          
  46.           txtX.text = new String(event.accelerationX);
  47.           txtY.text = new String(event.accelerationY);
  48.           txtZ.text = new String(event.accelerationZ);
  49.       }

Now just ask to test the emulator in Adobe Device Central CS5, we have something like this:

The argument is always the same, that the Symbian operating system is obsolete, that Nokia should invest in Google Android, and so on.
Now I’ll show my arguments by which I believe Nokia will not stop using the Symbian operating system on their handsets anytime soon, my arguments tab is based on two topics:
Market and strategy:

  • Nokia has a huge range of mobile phones being sold lately, running Symbian and all they sell a lot.
  • Who compares Symbian with Android or iPhone is making the wrong comparison, are users with different needs and purchasing power.
  • A user who buys a $30 device will not buy an actual $500 device.
  • Many users just want the equipment to make calls and send and receive SMS.

Technical

  • It is very profitable for Nokia devices produce low cost, or cheap handsets and of course, without an ability to run Android for example.
  • Nokia has the Qt (C++) to create applications for Symbian, Maemo and Meego. In the Android SDK is Java based and would require some partnership between Nokia and Google to create Qt applications for Android, something that does not exist yet.
  • Symbian Foundation already working on a new version of OS Symbian^4.

Are just a few points based on my experience. In short, Symbian still generates profit for Nokia and why give up something that is profitable? Example was the phone that worked as a flashlight that was very successful in Africa and Brazil. But I agree on one point, that Nokia was slow to realize that the model introduced by the touchscreen iPhone would become a trend. Now it seems he did a good job with the Nokia N8 and Symbian^3.

Nokia has created a library especially for working with Flash Lite feature that gives access to natively are not possible as access to the accelerometer, GPS, calendar, contacts etc.

I'll show a simple example of the use of geolocation with Flash Lite 3.0 and Nokia Platform Services.
Download the library Nokia and then save the directory under your operating system:

Nokia Platform Services only works on devices running Symbian S60 5th.

  • Mac - Copie para /Users//Library/Application/Support/Adobe/Flash CS5/en/Configuration/Classes/
  • Windows Vista - Extraia para /Users//AppData/Local/Adobe/Flash CS4/en/Configuration/Classes.
  • Windows XP - Extraia para //Local Settings/Application Data/Adobe/Flash CS5/en/Configuration/Classes/

We will start our first example:

  • Create a file of type ActionScript 2.0 and ask them to compile for Flash Lite 3.0 or 3.1. Or you can create directly from Adobe Device Central CS5.
  • Create a MovieClip and the instance name "mcScreen" and leave the stage.

We will now part of the encoding. We start by disabling the virtual keyboard (in my case to using a Nokia 5230) and setting the program to open on fullscreen.

PLAIN TEXT
ACTIONSCRIPT:
  1. fscommand2("DisableKeypadCompatibilityMode");
  2.       fscommand2("FullScreen", "true");

Add the class to import services from Nokia and declare the needed variables.

  3.       //api google maps
  4.       var API_KEY:String = "YOUR_API_KEY";
  5.       var latitude:Number;
  6.       var longitude:Number;
  7.       var myLocation:Service;
  8.       var mapLoader:MovieClipLoader;

I will use the Google Maps API to use the latitude and longitude to display the location on the map. Do I need to purchase a key Google website.
Instantiate the service and so we set the number of geolocation information from your smartphone.

  1. var myLocation = new Service("Service.Location", "ILocation");
  2.       var inParams = {LocationInformationClass:"GenericLocationInfo"};
  3.       var outParams = myLocation.GetLocation(inParams);

Just get the latitude and longitude have to load the map. One detail is that Google has no API for working with ActionScript 2.0, ActionScript 3.0 only. So what I will do is that Flash load an image from Google Maps via HTTP. You can get details by clicking here.

There you will learn how to easily develop for the greater global community of consumers of paid apps, and better understand how the apps are consumed by Ovi Shop, which already receives more than 1.7 million downloads a day in 180 countries - including Brasil.
Prepare yourself for a day filled with information for developers, where you'll learn about:

  • Using the new Nokia Qt SDK to create native applications for the advanced Nokia and other Nokia N8;
  • Using the Nokia Web Runtime and Flash Lite to create applications for the Nokia N8;
  • Best practice design of graphical interfaces for apps N8;
  • How to publish your application on Ovi Shop quickly and without subscription fees and certification;
  • The new incentives for developers to publish on Ovi Store;
  • The importance of their applications for Symbian ^ 3 and Ovi Shop for the Brazilian market;
  • As local developers have already achieved success in Ovi Store.

The idea is to connect with other developers and meet your local representatives from Nokia, the following areas: technical, sales and marketing, thus obtaining essential information and contacts you need to make your application more successful.

  5. deviceObject.DisableAutoRotation(true);

Service will use the class by passing the parameter sensor and then passing the criterion for a search the coordinates of the accelerometer.

PLAIN TEXT
ACTIONSCRIPT:
  1. var sensors = new Service("Service.Sensor", "ISensor");
  2. var inParam = {SearchCriterion:"AccelerometerAxis"};
  3. var outParams = sensors.FindSensorChannel(inParam);

Will return a series of values we use to "advise" the smartphone that our application will be updated with every change in value of the coordinates of the accelerometer through a callback method.

PLAIN TEXT
ACTIONSCRIPT:
  1. var channelInfo = outParams.ReturnValue;
  2. var channelId = channelInfo[0].ChannelId;
  3. var contextType = channelInfo[0].ContextType;
  4. var quantity = channelInfo[0].Quantity;
  5. var channelType = channelInfo[0].ChannelType;
  6. var location = channelInfo[0].Location;
  7. var vendorId = channelInfo[0].VendorId;
  8. var dataItemSize = channelInfo[0].DataItemSize;
  9. var channelDataTypeId = channelInfo[0].ChannelDataTypeId;
  10. var channelParams = {ChannelId:channelId, ContextType:contextType, Quantity:quantity, ChannelType:channelType, Location:location, VendorId:vendorId, DataItemSize:dataItemSize, ChannelDataTypeId:channelDataTypeId};
  11.  
  12. var inParams = {ListeningType:"ChannelData", ChannelInfoMap:channelParams};
  13. sensors.RegisterForNotification(inParams, callBack);
  14. function callBack(transactionID:String, eventID:String, outParam:Object)
  15. {
  16.     if (outParam.ErrorCode == 0)
  17.     {
  18.         var channelData = outParam.ReturnValue;
  19.         txtX.text = channelData.XAxisData;
  20.         txtY.text = channelData.YAxisData;
  21.         txtZ.text = channelData.ZAxisData;
  22.        
  23.         xSpeed -= channelData.XAxisData/NOISE;
  24.         ySpeed += channelData.YAxisData/NOISE;
  25.     }
  26. }

Then just update the x and y coordinates with the values and xSpeed ySpeed in our MovieClip. Made available at the source code to define how far the MovieClip can walk, or only in the area of our application.

You developer who likes to keep up, you know exactly what I'm talking about. In this article I gathered some links that those who want to start with mobile development in at least three different platform in which I had lately demands.

The mobile market is one of the fastest growing lately, and with it the demand for applications for this growing niche also bringing one more option for anyone who is a developer and new business opportunities

Among the platforms available for mobile development, we can highlight:

  • Java with JME
  • Nokia Qt, besides being able to use WRT(Web RunTime)
  • Flash Lite
  • Android SDK from Google with the addition of Adobe AIR and Flash Player 10.1
  • IPhone

'll Comment a little bit of each:

Java with JME
JME (Java Micro Edition) is the version that Sun offers for you to program in Java for mobile devices. It offers an enormous range of API's that were made specifically. Has a very complete documentation and several examples. I leave a link how to set up your environment for development JME.

Nokia Qt
Nokia offers Qt, Cross-plaftorm application and UI framework, with specific libraries for mobile devices (such as QTMobility). You program in C++ and there is an interface language like MXML. Has its own IDE and has emulators for Symbian S60, 40 and Symbian^3 beyond Maemo and Meego.

Adobe Flash Lite
Adobe Flash Lite still has space on the market, with a different version of the Flash player with some features specific to mobile devices. The development environment is to own Adobe Flash Professional and Adobe Device Central.

Google Android
Google offers for the Android platform a set of SDK's and emulators for the different versions of its operating system with each passing day it becomes more popular. It has a plugin for you to program in Eclipse, the Android Development Tools(ADT). The language used is Java. From Android 2.2 (Froyo) you have the option to create applications in Adobe AIR, the AIR runtime is installed on the device and you create the application using Adobe Flash Professional (which has an extension to create the files .apk) or Adobe Flash Builder.

Apple IPhone
Who wants to program for iPhone, ipad and the like, Apple provides an SDK. You use the Objective-C language, derived from C, and some interesting libraries developed for working with muiltitouch like Cocoa. We'll find a list of frameworks.

Well, we have options, it behooves us to analyze only that can best serve our customers. Should stay something about Windows Phone 7 because it seems to me very promising and deserves attention too.

We have the Flash Player 10.1 optimized for mobile and Adobe AIR 2.5 for Android, and with that Flash Lite would be in their final days.
I've read articles that argued that Adobe did not know that capitalize on the success that Macromedia has with Flash Lite in Japan and began to give priority for mobile systems only now. This can be a little truth, but Adobe does not mess around, now this with full force for a variety of devices, not only mobile.
Now our question which gave title to the article, along with Flash Player 10.1, Adobe released Flash Lite 4.0 also, being a version of Flash Player for devices with limited processing resources and memory but with support for ActionScript 3.0. See the list of features available here.
For one thing, each day brings more smartphones come with Android 2.2 (Froyo), which officially supports the Flash Player 10.1 and Adobe AIR 2.5. Also, we're seeing with Android smartphones (earlier) being updated with Froyo. That is, based on Flash contents tends to grow with these major smartphones. On the other hand so far, have only a smartphone officially announced with Flash Lite 4.0, the Nokia N8 and possibly Nokia C7, the question remains, still worthwhile to develop content for Flash Lite?
And my answer is YES, even for Flash Lite 3.0 or 3.1(ActionScript 2.0) especially for Nokia devices and why I say this. Let's see some facts:

So in conclusion, is a market for development and yet it is worth studying (and remember) Actionscript 2.0. I believe that we will have two or three years of life for Flash Lite.

O S60 Platform Services aims, to increase the power of Flash Lite, giving access to resources that natively, are not supported in Flash Lite still.
A API Services is supported on devices with Flash Lite 3.0 and Symbian S60 5th Edition including Nokia N97.
The following are some examples of uses of the API Services..
