Hello there,
I am an experienced programmer. I can do C/C++/Rust/assembly/Ruby/Perl/Python/ etc… The language itself is not a barrier.
The barrier to me is that I have never coded a single web or android application. I guess it must be surprising but I am more of a low-level programmer in my job (I develop a compiler backend) and I never really had the opportunity or idea to work on an app.
What would be a good starting point for making an android application?
A quick search got me this: https://google-developer-training.github.io/android-developer-fundamentals-course-concepts-v2/unit-1-get-started/lesson-1-build-your-first-app/1-1-c-your-first-android-app/1-1-c-your-first-android-app.html
Would it be a good starting point?
Side note: my app will not have to interact with any service. If I were to code it as a command-line program, it would not take me more than a day or two. The actual app would involve (for now) no more than a text field, a button, some logic attached to it - the hard part for me being to choose a framework to build it, “upload it” to my phone and use it.
Well, first of all, don’t try to use any of those languages and recognise that the language is a barrier. Choosing the right tool for the job is critical. Those are great languages… but as far as I know there are precisely zero good user interface frameworks available in those languages.
Just like a good function starts by picking a good name and argument list, a good user interface has to start with a good user interface design. Unfortunately user interfaces are complex beasts and it’s virtually impossible to get them right the first time. You absolutely must pick a user interface tool/language/etc which allows you to make major changes (including scrapping the whole thing and stating over) in a short amount of time (minutes, preferably).
The best user interface languages are declarative ones. You should be describing the structure of your interface, largely ignoring the functionality - that’s something which can either be done for you by the framework or done yourself as a completely separate task, in a different file, maybe even a different git repository, and probably a different programming language.
It should be possible to get a rough interactive version of your app up and running very quickly, so you can test it, learn what works/doesn’t work, show it to other people, and you need to be able to rewrite entire sections of the interface by simply rewriting two or three lines of source code.
I recommend HTML/CSS as a good starting point. After you’ve got your head around that first (it won’t take long, it’s relatively simple). After that look into more modern tools like React Native. Learn to crawl before trying to walk.
The article you linked to is just wrong. It suggests this process:
Step 4 needs to be tightly integrated into Step 1. Start working on step 2 after you have finished step 4 (and then, after you’ve done steps 2 and 3, you will need to repeat step 4).
I encourage you to read less articles, they’re often giving really bad advice and without experience it’s impossible to know which ones are good advice. Instead pay for ChatGPT Plus and just ask it questions. “How do I make a button in HTML/CSS” or “how do I make it execute code when the user clicks it” or “how can I deploy a HTML/CSS/JavaScript app on Android”.
@abhibeckert @potterman28wxcv You could use Ruby on Rails or Python’s Dash.
Please; no.
Was this an attempt at a joke? All of that stuff can be found on W3Schools: no tech-evangelist articles, no paid subscription, no ChatGPT. I’ll even throw in the links. (I maintain that given OP’s project parameters, he doesn’t need an app at all, it just needs to be accessible from his phone - a web page may suffice.)
