iOS Question Looking for consult on simultaneous iOS+Android development

I am really glad with these tools. Firstly I created the layouts from the b4a layouts with the bal2bil tool. Then what I did was to create some functions that are acting as interfaces between the B4A side and the B4i side. F.e. a class that emulates the runtime permissions and has a function GetSafeDirDefaultExternal that acts exactly as the function rp.GetSafeDirDefaultExternal(""). Then the 99% of the code of the application will be reusable with slight changes if no native java functions are used.

Hello!
You have made the right choice to come here. I'll answer your questions honestly with my experience with B4

Are you glad you chose these tools?
Yes! I grew up learning VB.Net, and eventually moved on to Eclipse/Android-Studios and Xamarin to create my mobile apps. I found B4A, and instantly fell in love. I've been using it for over 4 years, where building mobile apps is required.

Do you think you saved significant time over the native SDKs?
Definitely. B4X comes with so many useful tools as far as encoding, communication, DB support, etc.. It's so easy to write code, and the visual designer is VERY useful and time-saving.
Not only that, but B4X has so many advanced development tools. Wireless debugging, Code hot-swap, logging, etc. Shipment is very easy. I hate Macs, which are required with other platforms. B4i doesn't require a Mac whatsoever with the remote servers. B4X also has the fastest debugging in my experience. I'm sick and tired of waiting 15+ seconds for a debug on other platforms. B4A debugs my biggest projects in under 2 seconds

Did you achieve enough reuse to make it a smart choice, as opposed to choosing a Javascript-based cross platform technology?
B4X makes it super duper easy to translate from B4A->B4i, as long as you don't use a whole lot of native views. If I use only B4X and custom views, my project translations usually only take 1-2 days or less. It depends on the size of the project. 99% of the actual class code is reusable in my experience.

Does the product now contain support for building a single layout in a responsive manner, as opposed to having to essentially hard code to a screen resolution?
I think it's had the designer scripting for awhile. That allows you to create responsive layouts. However, now there are anchors, which are absolutely fantastic.


Overall, I would definitely recommend B4X. Everything is native, meaning no runtime. You aren't going to have a 40MB hello world application, like in other platforms. A hello world application will be 0.01 MB. The speed is going to be optimum as well. Expect to build a fully native high-quality application, in about 1/4 of the amount of time. That's what I have experienced personally.

I appreciate these very helpful responses. Thank you.

I mainly write thinkering games.

After getting used to the IOS difference it was just a matter of writing the game first for Android then reuse the entire class in the IOS project and work away the differences with conditional compiling.

With the birth of XUI things got even easier and a lot of these differences are captured into XUI methods.
Which means smaller sources and easier to follow without all these #IFs.
The only big exeptions here are mouse events. for example on one it's just _Click on the other it's _MouseClicked with or without extra mouse event type.
It would be nice if this was the same over all platforms maybe it's on the to-do list for later XUI extentions.

The current project was even done in B4J first with the same 'ui strategy' kept in mind so that a nearly instant port to Android or IOS is possible.

It's just a matter of constructing things right from the start.

If you rely a lot on forms then things are harder I guess as most things look different from one OS to the other but you can always create your own set of elements
so that it looks exactly the same on each.

It depends on how far you want to push things.

Based on my experience:

• Are you glad you chose these tools?

• Do you think you saved significant time over the native SDKs?

• Did you achieve enough reuse to make it a smart choice, as opposed to choosing a Javascript-based cross platform technology?

• Does the product now contain support for building a single layout in a responsive manner, as opposed to having to essentially hard code to a screen resolution?

There is still some bias against using a Basic based language, both from other developers and some clients. I have started to refer to B4X as a low-code tool-set/environment which whilst not being strictly true, seems to work.

I would also like to add that b4i actually saves you money which is absolutely crucial for low budget developers. I am referring to the hosted builder option which with 25 dollars a year provides you the chance to compile your app and upload to Apple Store without being forced to buy a mac. The price for the hosted builder is fair and if you do the maths (supposingly you would get a adequately good mac of around 900 euros) it would take 36 years to pay the same amount. In 36 years if my height is still positive I will probably be a pensioner and probably I will not remember where my p*n*s is located . Given this approach I would say it definetely worths it to use the b4x universe because it is full of benefits other IDEs do not provide especially for low budget developers.

I really appreciate all the feedback.

For an independent developer, finding affordable tools is indeed key.

But my ask is for a corporation. The tool cost itself isn't the issue. But key to us is:
- Being able to reuse most source across web, iOS, and Android
- Tools that are reliable and worthy of building solutions to be delivered to thousands of end users
- Tools that have a high probability of still being around and viable in, say, 5 years
- Tools that wouldn't have special requirements for the web; not requiring JavaFX.

If the 3 here are a match, I'm interested in learning more, but it isn't clear to me yet.

The best way to really evaluate any tool is to use it on a real project...

Yes, One of my apps is used by > 10K users each weekend and I'm sure other members have more usage than that.

Yes, I would not have chosen this tool if I didn't believe it had a decent lifetime.

This is your problem. Not sure what your objection to JavaFX is, but B4J certainly uses it.

Perhaps your search needs to continue. I'm sure the perfect tool is out there waiting for you to find it.

Good luck!

I think he means sites running entirely on java like we had old config tools/sites for pabx, routers, switches etc...

You can use B4J/java as backend but it's not required to work with a B4X based app/client.

If you prefer PHP or .NET as your corporation might have a developer for that you can use that without any problem while still using B4A for Android and B4i for IOS.
there's enough ways to interchange data between the two.

@sorex , my mistake. Thanks for that.

• Does the product now contain support for building a single layout in a responsive manner, as opposed to having to essentially hard code to a screen resolution? You can't share the layouts between projects, but you can copy/paste from one platform to another in the designer. If you use XUI views and some common views, you can copy all your views. It ends up looking nearly identical across platforms. You can fine-tune your layout with designer script code, which you can also copy from one platform to the other (has to be done manually). B4x really shines in this area, unlike popular new frameworks like Flutter, which is cumbersome and time consuming to manually code all of your UI.

I use b4a/b4i for my apps and have over 20 million downloads with my apps. Recently, it became possible to share nearly all of your code across platforms. I developed a class and strategy for sharing code across platforms. I have successfully used this strategy to share almost all of my b4a code in a b4i app. I have experimented with and used various cross platform development systems. One was web-based, which I used to develop apps for Android, iOS, and the web. The b4x system is superior to everything else I have tried when using my strategy for sharing code.

As far as I know, there is not a way to deploy a b4x app to the web. You can write a web server, but you can't compile b4x to html/javascript. If you don't need a web app, and have experience with the basic language, I highly recommend b4x for cross platform Android/iOS apps. I am migrating my HTML/js cross platform apps to b4x. I have no regrets about using b4x. It is not perfect, but I like it better than anything else I have tried.

Here is my cross platform development strategy and class for b4i. One thing that is unrivaled with b4x is its support community. There are many helpful experts, and best of all, Erel who is the author of the product often personally answers questions, which can't be beat.

Across web, iOS and Android is way too much to ask from a tool. Even visual studio does not provide this possibility to the maximum but partially. I do not know why you are interested for the web, but if it is about a back end you can easily use B4x for Android and iOS and use .NET for the back end having the two sides (mobile and web) communicating through JSON.

I suppose your question has to do with only the front end in the mobile side and the answer is yes they are. If you refer though to web also, then the answer is that it is up to you to create scalable server integration or have a load divider in a main server to multiple servers.

The probability is high unless Erel's company decide or be forced to stop developing the B4x tools.

I cannot answer this question since I have not used B4J for a long time. My programming approach besides B4X is .NET and in .NET a lot of things are done differently.


Have a nice day
