One of the questions you do lately is the possible death of Flash Lite. 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.

This business model has become a fad in the world, you provide your application through a large company, we have examples such as Apple’s App Store, Nokia with Ovi Store, Google Android Market. The advantages are many and generate greater confidence for the user and off course that Adobe could not be left out.
Previously called Shibuya, now Adobe Melrose seeks to offer basically three types of services for those who develop applications on Adobe AIR:

  • Try and Buy – When you are developing your AIR application, you simply embed the licensing SWC in your application, enter a few lines of code and specify the price and trial periods online.
  • Monetize -When end user customers purchase your application, the Melrose service keeps track of the income from each of your applications. You get paid at a regular interval, typically once a month.
  • View analytics – Reports are available online via the Adobe Developer Connection site. In this initial release you’ll be able to view reporting information regarding revenue, active trials, expired trials and downloads. This information is available for everywhere you use Melrose-not just for downloads from the Adobe AIR Marketplace.

We often need our system can store data locally without the need for a robust database as a MySQL or SQL Server, or even that data can be stored locally for later synchronization with a remote database. Adobe AIR offers the possibility of working with database locally, your bank is based on the SQLite database, the more used to this kind of need to be very fast and easy to work with. Was added transaction support in Adobe AIR 2.0.
Let's do a simple example, start with the SQLConnection class, she will be responsible for connecting with our local bank, it is also defined that the database will be used only in memory or whether it created a local file (extension. db).

PLAIN TEXT
ACTIONSCRIPT3:
  1. conn = new SQLConnection();
  2. try
  3.             {
  4.                 conn.open(dbFile);//conn.open(null) passe null para o banco ser criado somente em memoria
  5.             }
  6.             catch(err:Error)
  7.             {
  8.                 trace(ObjectUtil.toString(err));
  9.                 return;
  10.             }

In this case, I am creating a local file to the database. dbfiles is an instance of the File class:

PLAIN TEXT
ACTIONSCRIPT3:
  1. dbFile = File.applicationStorageDirectory.resolvePath("dbFile.db");

Having created our database, we create our table for storing data. We will use the class SQLStatement.

PLAIN TEXT
ACTIONSCRIPT3:
  1. createStmt = new SQLStatement();
  2.             createStmt.sqlConnection = conn;

We will pass by the SQL string to create the table then to be performed by AIR:

PLAIN TEXT
ACTIONSCRIPT3:
  1. var sql:String = "";
  2.             sql += "CREATE TABLE IF NOT EXISTS contato (";
  3.             sql += "    id  INTEGER PRIMARY KEY AUTOINCREMENT,";
  4.             sql += "    nome    TEXT,";
  5.             sql += "    email   TEXT";
  6.             sql += ")";
  7. createStmt.text = sql;
  8. try
  9.             {
  10.                 createStmt.execute();
  11.             }
  12.             catch(error:SQLError)
  13.             {
  14.                 trace("CREATE TABLE error:", error);
  15.                 trace("error.message:", error.message);
  16.                 trace("error.details:", error.details);
  17.                 return void;
  18.             }

We have our database and tables created, let's create a form to enter some data in the database:

PLAIN TEXT
ACTIONSCRIPT3:
  1. insertStmt = new SQLStatement();
  2.             insertStmt.sqlConnection = conn;
  3.             var sql:String = "";
  4.             sql += "INSERT INTO contatos (nome, email) ";
  5.             sql += "VALUES ('"+txtNome.text+"', '"+txtEmail.text+"')";
  6.             insertStmt.text = sql;
  7.            
  8.             try
  9.             {
  10.                 insertStmt.execute();
  11.             }
  12.             catch (error:SQLError)
  13.             {
  14.                 trace("INSERT error:", error);
  15.                 trace("error.message:", error.message);
  16.                 trace("error.details:", error.details);
  17.                 return void;
  18.             }

Now just create the method to execute the select

PLAIN TEXT
ACTIONSCRIPT3:
  1. selectStmt = new SQLStatement();
  2.             selectStmt.sqlConnection = conn;
  3.             var sql:String = "SELECT id, nome, email FROM contatos";
  4.             selectStmt.text = sql;
  5.            
  6.             try
  7.             {
  8.                 selectStmt.execute();
  9.             }
  10.             catch (error:SQLError)
  11.             {
  12.                 trace("SELECT error:", error);
  13.                 trace("error.message:", error.message);
  14.                 trace("error.details:", error.details);
  15.                 return;
  16.             }
  17.            
  18.             var result:SQLResult = selectStmt.getResult();
  19.             dg.dataProvider = result.data;

Adobe Flash Media Live Encoder is a free software that Adobe offers for you to use to convey stream directly to a server and deploy Flash Media Server for your Web site or application.
Among the options available are:

  • High Quality Encode
  • H264 / VP6 Video
  • AAC / MP3 Audio
  • Command-line
  • Error Handling
  • VITC Timecode
  • Pre-processing
  • Live Metadata
  • Local Archive
  • DVR Support

With support for a variety of capture devices like webcam video, SDI, Composite, Component, Firewire.
There are cases where you need to restrict access to Flash Media Server via the Flash Media Live Encoder for that Adobe has created a plugin that is installed on your server, Flash Media Server, Flash Media Server Authentication Add-in.
Para instalar esse plugin, siga os seguintes passos:
Download and install Flash Media Server Authentication Add-in
https://www.adobe.com/cfusion/entitlement/index.cfm?e=fmle3
Then use the command prompt and go to conf directory Flash Media Server
C:\Arquivos de programas\Adobe\Flash Media Server 3.5\conf
To create a new user, simply use the command:

users add -u user -p 123

Where is the user login and password is 123
Note that the directory C:\Arquivos de programas\Adobe\Flash Media Server 3.5\conf Now there are two files, users.exe and users.dat, logins and passwords are saved in users.dat
Now simply open the Flash Media Live Encoder and try to connect, it asks login and password.
One of the advantages of Flash Media Live Encoder is that it recognizes most devices that capture the Flash Player.

Needed to implement a feature that in a AdvancedDataGrid hours ordering the data by the first letter or not. First time I thought it was very difficult as I had done something similar in another project where it should split by examples hours the servers, time servers of the instances.
When looking at this old project, I thought it was very complicated and hard to understand, I returned to livedocs to study a little more.
I used the example of Adobe and basic with some adjustments, I saw what I wanted to do was simpler than I thought.
I have a data layer for simple demonstration, and at first, my food grid with it.

A CheckBox is adding a listener to tell me when he is selected or not.

PLAIN TEXT
MXML:
  1. <mx:CheckBox id="ckGroup" label="Checkbox"/>

My function that handles the event of the CheckBox will do the work group and ungroup data.

PLAIN TEXT
ACTIONSCRIPT:
  1. private function handlerCheck(evt:Event):void
  2. {
  3.     if(ckGroup.selected)
  4.         {
  5.         trace("selected");
  6.         gc.source = dpFlat;
  7.         gc.refresh();
  8.         hView = new HierarchicalCollectionView(gc);
  9.         myADG.dataProvider = hView;
  10.     }
  11.     else
  12.         {
  13.         trace("no selected");
  14.         myADG.dataProvider = dpFlat;
  15.     }
  16.  }

I am using the class GroupCollection which is responsible for grouping my data for a particular field to be displayed in AdvancedDataGrid.

PLAIN TEXT
MXML:
  1. <mx:GroupingCollection id="gc" source="{dpFlat}">
  2.         <mx:grouping>
  3.             <mx:Grouping>
  4.        <!--         <mx:GroupingField name="Region"/>-->
  5.                 <mx:GroupingField name="Territory"/>
  6.             </mx:Grouping>
  7.         </mx:grouping>
  8.     </mx:GroupingCollection>

Turning then to HierarchicalCollectionView that provides a hierarchical view of my data.

PLAIN TEXT
ACTIONSCRIPT:
  1. gc.source = dpFlat;
  2. gc.refresh();
  3. hView = new HierarchicalCollectionView(gc);
  4. myADG.dataProvider = hView;

I was called to resolve a problem with the protection of the contents of a client, the problem was that somebody malicious was stealing their live streams.
He simply took the html code of the site and pasted on her website, so you may transmit the content in your blog. The player in question was not developed by me, so I did not even bother to look at the source, I decided to go directly to the Flash Media Server.
Based on the documentation from Adobe, I decided in a very simple code main.asc is as follows:

PLAIN TEXT
JAVASCRIPT:
  1. trace("init application...");
  2.  
  3. var VALID_REFERRER = "http://www.mydomain.com.br/mySwf.swf";
  4. var VALID_PAGEURL = "http://www.mydomain.com.br/myPage.html";
  5.  
  6. application.onAppStart = function ()
  7. {
  8.     trace("init app...");
  9.     trace("onAppStart> " + application.name + " is starting at " + new Date());
  10. };
  11.  
  12. application.onStatus = function (info)
  13. {
  14.    trace("onStatus> info.level: " + info.level + ", info.code: " + info.code);
  15.    trace("onStatus> info.description: " + info.description);
  16.    trace("onStatus> info.details: " + info.details);
  17. };
  18.  
  19. application.onConnect = function (client)
  20. {
  21.     if ((client.referrer == VALID_REFERRER && client.pageUrl == VALID_PAGEURL))
  22.     {
  23.         trace("acesso permitido");
  24.         application.acceptConnection(client);
  25.     }
  26.     else
  27.     {
  28.         trace("acesso indevido");
  29.         application.rejectConnection(client)
  30.     }
  31.     trace("onConnect> client.ip: " + client.ip);
  32.     trace("onConnect> client.pageUrl: " + client.pageUrl);
  33.     trace("onConnect> client.agent: " + client.agent);
  34.     trace("onConnect> client.referrer: " + client.referrer);
  35.     trace("onConnect> client.protocol: " + client.protocol);
  36. };
  37.  
  38. application.onDisconnect = function (client)
  39. {
  40.     trace("onDisconnect> client.name: " + client.name)
  41.     trace("onDisconnect> disconnecting at: " + new Date());
  42. };
  43.  
  44. application.onAppStop = function (info)
  45. {
  46.    trace("onAppStop> application.name: " + application.name);
  47.    trace("onAppStop> stopping at " + new Date());
  48.    trace("onAppStop> info.level: " + info.level);
  49.    trace("onAppStop> info.code: " + info.code);
  50.    trace("onAppStop> info.description: " + info.description);
  51. };

The API Flash Media Server is very powerful and contains many interesting features, one of them is the ability to know where exactly the connection is coming from the swf. This passage has solved the problem with the constants declared at the beginning of the file.

PLAIN TEXT
JAVASCRIPT:
  1. if ((client.referrer == VALID_REFERRER && client.pageUrl == VALID_PAGEURL))
  2.     {
  3.         trace("acesso permitido");
  4.         application.acceptConnection(client);
  5.     }
  6.     else
  7.     {
  8.         trace("acesso indevido");
  9.         application.rejectConnection(client)
  10.     }

In short, so the connection is made with Flash Media Server is attempting to connect comes from a SWF and HTML defined by me.
A very simple solution but it solved the problem :D
As a last resort, the thief also copied the swf client and put into your blog :P

This post was originally written several years ago, it was only as a draft and strangely remains current.

Sometimes I see on the Internet some movement "anti-Flash", something really strange, it seems religion. There is a culture of saying that Flash is a program "to make a ball go" or that "Flash has accessibility zero, this is very far from the truth. it is possible to make extremely complex applications with Flash. And when there is a kind of "dispute" between AJAX X FLASH Flash x Silverlight Flash x HTML5. From time to time there is a new "Flash-killer", I think they are different technologies and complement. I see the same kind of radicalism in relation to PHP X Cold Fusion, ASP X PHP, PHP X PHYTON, Open Source X Proprietary etc.
I have also been very radical, defending PHP tooth and nail, spoke ill of any other language that was not PHP without even know it, but I realized that those who still think that way, limits their opportunities to major world today no matter what tool you use but how you use the tool, who heard "The bad employee blames his tools work"?.
Always worked with Flash and PHP, when I entered the BANCOOB, I felt compelled to learn Java, was a challenge that could overcome. Shortly after I entered the migration project, which would have to program in C # and Visual Basic, many of my friends simply do not accept into the project. I heard things like, "look at my curriculum and see if it is VB" and called the loose, but the end result was a great experience for me, I was able to grow much.
I have already been many philosophical discussions, and today I have no more patience for it when I see that this conversation tends to radicalism or religion, I lose the will to fully discuss.
Working with Flash since version 5, I followed closely the development of the tool, and the long ceased to be just a "plugin" to become a development platform for several devices. Of course with that, disrespect the competition, which is great. After all we must always move.

Developers who do not work with Flash, underestimate the power he has.

I'm not the only one who thinks this story that "one will replace the other" makes no sense, to own Adobe preaches that the two work perfectly together, so that the Adobe Dreamweaver CS5 already has support HTML5.
The launch of the iPad was the trigger for the so-called "anti-Flash". it mounted the perfect setting for a healthy discussion, where we could point out the strengths and weaknesses of a given technology and how it can be improved. But what we have seen is just the opposite, I've seen several articles and comments from people simply saying "I hate Flash", sites with sensational headlines(what they did to the post of Lee was disgusting!!!), Each week a different rumor that people believe without checking the sources and the same conversation 5 years ago.

Meanwhile, the client ta little matter if you use this tool or that, what matters to him is that you do the job.

The bad employee blames his tools work.
