On what to write the application engine if you need multiplatform?

Question

Programming

Good afternoon!

After a long break, I decided to continue working on the visual training program. Not another scam :). The method has been tested and patented.
There is a fully working version on Delphi under Windows. But now I want:
1. Multiplatform. Windows, Android, iOS, smartphone versions.
2. Online and offline clients.

On what to write the engine? Flash? I have all the algorithms written in the previous version on AS3.
I would like to use the developments ...
Did I understand correctly that Flash will not be supported ONLY in mobile browsers?
Those. you can write your own application without fear?

Or maybe there are other ways? Not a programmer himself (however, he wrote algorithms on AS3 himself), a customer.
But I wanted to understand ... To somehow evaluate the proposals of the developers.
I understand that a project manager is needed. I'm looking for ...

I apologize if I illiterately formulated the question.

Answer 1

html+js is the best. You can look at HTML5 if you work for the future. Now old browsers do not understand it.

Answer 2

>> There is a fully working version on Delphi under Windows.
Overtake on FireMonkey (new platform in Delphi, better than the old VCL) - you will have multi-platform now (Windows, Mac OS X, + styling on Windows 8).
In the near future there will be iOS (yes, on Delphi).
The next one is Android.
Since "visual training" is 100% applied, Delphi will be more than enough.

Answer 3

a. well, you can safely cut on js.

Answer 4

C++ + Qt? However, it's probably not for you...

Answer 5

I think monkeycoder.co.nz/

Answer 6

Write under AIR. It's on both mobile and desktop. For desktop, you can make an installation file. Plus, it will be possible to use ready-made AS3 code without any problems.
As for mobile platforms. If we are talking specifically about the application, and not about the site with interactive content, then the issue of mobile browsers is irrelevant. AIR applications for smartphones are full-fledged applications that can be freely distributed through application stores.
Flex is a framework for developing interfaces in AS3. A very powerful thing. But for AIR applications, you can also write in pure AS3.

Answer 7

If the task is to cover as many platforms as possible, then the algorithms can be translated into Java (desktop, android) and Objective C (iphone). And the face for Android and iphone will have to be developed for each platform.

Answer 8

As a C++/QT variant
True, the port for iOS has not yet been completed.
