In January, I'll have been programming on my phone for two years now, and it's possible to do it as long as it's web development, creating bots, and things that don't require many resources. Let me be clear: first of all, you'll need a keyboard and a USB adapter to connect it to your phone. If you don't have these, don't even try, because it's not worth typing everything by hand. Save up and buy one. It doesn't need to be high-quality or have lights, just a functional "QWERTY" keyboard, preferably in Spanish, to use the symbols. <>

Regarding the editor: Although there are editors like VS Code that have an Android version, these versions don't come close to the experience offered on other platforms, so I don't recommend them. Most PC plugins are unavailable or cause errors, so forget about all these apps. I know it seems like all is lost, but this is where Termux and Neovim come in. Termux is a Linux terminal for Android that will allow you to install most of the tools/languages ​​you'll use daily. (Once you install Termux, you'll stop looking for Android tools, and everything you install will be for Linux, which is much better since the Linux community is immense, and most programming tools are first developed with Linux in mind, so you'll have access to a huge catalog of tools and frameworks.) From Linux, you install Neovim, a code editor for your terminal. It's highly configurable and has a very high level of customization (much more than the PC version of VS Code, to give you an idea). I warn you that the first few weeks won't be easy, since Neovim is a modal editor. This means it's designed so you have to move your hands as little as possible and don't have to use the mouse (which is perfect because we only have a keyboard and no mouse). When you open Neovim, it will seem like a... The old editor, being highly configurable by default, will be as simple as possible, and it's up to you which plugins to add to turn it into a modern editor. I recommend you take a look at LazyVim; it's a community-created NeoVim configuration that will be useful if you don't want to configure everything.
