PACKT Publishing Book Review: “Gideros Mobile Game Development”

As you probably know, I did some reviews on PACKT Publishing technical books. Now I did a review on a new book about Gideros Mobile. At bit Time Software we used to create mobile games too and in the last months some of them have been built with Gideros Mobile (we do also training on the Gideros Mobile framework. If you are interested, check the contact me section ad write me an email).

The last game released by bit Time Software, is written with Gideros Mobile and is available for Android and iOS devices. It is called Math Brain HD and it’s free. Here’s the game icon.

At the last DROIDCON in Turin, IT, we held a speech about the Gideros Mobile framework.

So, being an advanced user, I’ve been really pleased to do this book review for PACKTPUB.

The title of the book is: Gideros Mobile Game Development

The book cover

Here you can find the book page on PACKT Publishing web site

Here’s a bullet list of considerations about the book. These are a sum of feelings, mine and from my colleague at bit Time SoftwareDaniele Spinetti.

Is’s really simple to read, also for non native english people, and the contents are very well organized. When you finish to read the book, you are able to create a good level game, not a trivial one. All the topics related to the complete Gideros Mobile software stack are covered.

During the book, the author incrementally starts to use the most popular plugin for the Gideros Mobile, so you are getting familiar with the “fantastic plugin world” from the start.

IMHO it’s a good book.

However, if you want to find some cons, sometimes seems that it goes into too much details getting too trivial (e.g. zindex).

Sending Android Intents from Delphi (Part 2)

Some months ago I wrote a post with title “Sending Android Intents from Delphi (Part 1)”. In that post I promised to write a 2nd part… here’s it is!

This time I want to play a video deployed with my APK using an external player.

Some informations are available on the Internet, but to correctly know how to play the video I’ve to inspect my Nexus 5 with the LogCat while using the default file manager to start the default video player.

The app main form  is shown below

The main form
The main form


I’ve added an mp4 video file using the deployment manager.

This is the code under the button click event

procedure TForm1.Button1Click(Sender: TObject);
  Intent: JIntent;
  FileName, DestFileName: string;
  Data: Jnet_Uri;
  CompName: JComponentName;
  VIDEO_FILENAME = 'videoviewdemo.mp4';
  FileName := System.IOUtils.TPath.GetDocumentsPath + PathDelim + VIDEO_FILENAME;
  DestFileName := TPath.GetSharedDownloadsPath + PathDelim + VIDEO_FILENAME;
  // Copy the file into a public path (you can use any public path)
  TFile.Copy(FileName, DestFileName, true);
  Data := TJnet_Uri.JavaClass.parse(StringToJString('file://' + DestFileName));
  Intent := TJIntent.Create;
  if CheckBox1.IsChecked then
    CompName := TJComponentName.JavaClass.init(StringToJString('android'),
  Intent.setDataAndType(Data, StringToJString('video/mp4'));
    on E: Exception do
      Label1.Text := E.Message;

Using the checkbox you can force the OS to show the ResolverActivity.

Sending Android Intents from Delphi (Part 1)

As you probably know, I work for the italian embarcadero representative (, so last week, I’ve been in Milan (Italy) with the Delphi Product Manager Marco Cantù, to show the new Delphi XE5 for Android (and iOS…).

Users (old and new) were enthusiastics. The Delphi-WAY combined with the Android openness and flexibility, is really a good way to develop mobile apps for the business customers.

So, after the initial demos some users were interested in sending Android Intents from their Delphi app.

I’ve builded some demos about Intents, so I showed those demos to them (in the next weeks there will be many Delphi for Android training in Italy, so I’ve build those demo in advance)

In Delphi XE5 you can call java classes from the Google SDK. So I started investigating hot to do this.

There are a lot of possibilities, and I’m still doing research, but this is a simple Intent send demos.

The Intents demo app
The Intents demo app


This is the code under the first button.

procedure THeaderFooterForm.Button1Click(Sender: TObject);
  Intent: JIntent;
  // String url = "";
  // Intent i = new Intent(Intent.ACTION_VIEW);
  // i.setData(Uri.parse(url));
  // startActivity(i);

  Intent := TJIntent.Create;

Simple, isn’t it?

With this piece of code, you cann open your device browser to a web site (my blog in the snippet).

Click on the first button and you will be redirected to this blog.

Open browser with intent
Open browser with intent


Intents are REALLY powerfull

With the next snippet, you can send piece of data (e.g. text) to other apps. You dont have to know the apps in advance, Android will do the match with the Implicit Intent. (It is similat to the TShowShareSheet action).

procedure THeaderFooterForm.Button2Click(Sender: TObject);
  Intent: JIntent;
  // Intent intent = new Intent(Intent.ACTION_SEND);
  // intent.setType("text/plain");
  // intent.putExtra(android.content.Intent.EXTRA_TEXT, "Android Rocks!!!");
  // startActivity(intent);

  Intent := TJIntent.Create;
    StringToJString('Delphi Rocks!!!'));
Chose wich apps shoud be launched to handle the intent (and the text)
Chose wich apps shoud be launched to handle the intent (and the text)


Now, if you choose Twitter, you will get this screen.

Intent handle by twitter app
Intent handle by twitter app


I’ve demos about placing a call, sending an SMS, show a PDF file, accessing different kind of storage etc.
In the next part of this mini series I’ll show some other snippets.

There is still many areas to explore…

  • Services
  • BroadcastReceiver
  • Widget
  • Bluetooth
  • I/O
  • …?

I’ll keep you informed…

ITDevCon2011 Android App

In less that a week, ITDevCon2011 will begin. To allow all members (and to let decide who is still undecided) to take advantage of the two days of intense training, we have just published the application ITDevCON2011 on the Android Market. You’ll find full conference program, speaker profiles and information about the sponsors.
In addition, you can define your favorite speeches in order to be alerted immediately before the start of the speech.

You can vote and comment every speech. You can comment now by entering your expectations for the speech or some clarifications on the content. The vote, however, is allow only after the speech.
From a technical standpoint, this Android application uses a Delphi DataSnap REST service and the DataSnap Mobile Connectors for Android.

For those interested in the “Application Making Of” during the conference may attend the speech of Salvatore Sparacino illustrating the various steps of development and the technological solutions adopted. Very cool! Salvatore will talk about a REAL app, not only a demo!

To define your training profile, add rates and comments, you have to use the code provided at registration. If you’ll not attend, or you have not received your access code, you can use the application as “anomymous.” In this case, you cannot save your favorite speeches or votes or comments.

DataSnap Mobile Connectors in RAD Studio XE2

WARNING! I’ve been authorized by EMBARCADERO to write about RAD Studio XE2.

RAD Studio XE2 is full of nice and exciting features. One of the most interesting IMHO is the DataSnap extension called “Mobile Connectors”.

In the past, I’ve talked about connecting and using your datasnap REST service with Android, creating ad-hoc json messages and manually parsing the returned json messages. With RAD Studio XE2 this is no longer needed. If you have a DataSnap REST service, you can automatically generate the proxy connector for the major mobile platforms. Yes, just like you have been doing with Delphi or C++ since Delphi 2010.

DataSnap XE2 version supports 4 mobile platforms:

  • Android (Using Java)
  • BlackBerry (Using Java)
  • Windows Phone (Using C#)
  • iOS 4.2 (Using ObjectiveC)

If you want to enable your DataSnap server for the Mobile Connectors you have to explicitely check the feature in the “New DataSnap Server” wizard.

The generated proxies support all the standard Delphi types and maps them to the native target language. Some of the most used Delphi types (e.g. TStream, TDBXReader and so on) have been rewritten in the target language to allows a greater compatibility and a simpler programming interface. The functionalities of the various Delphi classes are not-one-to-one with the Delphi version, but  similar.

From a remote (or local) machine you can download the generated proxy and all the required files using a tool called “Win32ProxyDownloader.exe” which is in the bin folder of your RAD Studio installation. In my FieldTest version, this tool called without parameters, shows its help.

As usual you should have the RAD Studio bin folder in your PATH environment variable, so you can change your current directory to where you want the proxy and write this command in a commandprompt window:

Win32ProxyDownloader -language java_android -host localhost:8080

The proxy and all the needed files are ready in the current directory.

Mat DeLong wrote a very nice Eclipse plugin to use the proxy downloader directly from Android or BlackBerry development environment. You can find this plugin here.

You know that Android is my preferred mobile platform, don’t you?

So, let’s go with an Android example.

To use the generated java proxy, in an Android client application I can write something like this:

//Create the connection
connection = new DSRESTConnection();
//Create the proxy
proxy = new DSProxy.TServerMethods1(connection);
//Use a simple remote method
int sum = proxy.Sum(1,4));
//Use a complex remote method
TStream inStream = null;
TStream outStream = null;
String s = "abc";
inStream = new TStream(s.getBytes());
outStream = proxy.DoSomethigWithATStream(inStream, sum, "Hello DataSnap Mobile Connectors");
//here I can use the java TStream type

All the custom Delphi types (e.g. TPerson) are mapped on the target platform as TJSONObject. All the TJSONValue hierarchy has been ported, with a very similar interface, to the target platform as a wrapper of the native JSON classes.

So, you can write code as the following (Java on Android):

TJSONObject jobj = new TJSONObject();
jobj.addPairs("firstname", "Daniele");
jobj.addPairs("lastname", "Teti");
jobj.addPairs("age", 31);
jobj.addPairs(new TJSONPair("nickname", new TJSONString("Spiderman")));
if (jobj.has("firstname"))

All the proxies work in a similar way except for the Windows Phone one. Indeed, the WP proxy is asynchronous because Microsoft does not allow a sinchronous http request in the main thread. All the proxies are thread safe.

The proxies are generated on the fly by a set of specialized writers. The TDSProxyGenerator component is in charge of generate the actual proxy code in the target language/platform using one of the specialized generators.

In the next figure you can see all the available proxy generators. Some of them are there since Delphi XE but all the mobile platforms have been added in XE2.

That’s all for now.

RAD Studio XE2 will be officially presented all over the world during the “RADStudio XE2 World Tour”.

You can find the list of all launch events in the RADStudio XE2 World Tour page.

I’ll be a presenter at 3 launch events in Italy and United Arab Emitates.

These are the events where I’ll be (click to register):

RAD Studio XE2 had a lot of new features. This is really the BEST ever Delphi version since version 1.

I’ll blog about other XE2 features mostly Delphi related (as usual) so stay tuned.
