The Redmi Note 8 Pro, which is powered by the MediaTek Helio G90T, was originally conceived as a gaming hub for the budget segment, but its computing power and Google Play Services support make it a great base for mobile development. Many aspiring programmers underestimate the capabilities of Android devices, believing that writing code necessarily requires a powerful desktop, but the modern ecosystem allows you to turn the phone into a full-fledged workstation.
In this article, we will look at not just installing a code editor, but deep system setup that will allow you to compile projects, debug them, and even run local servers right on your device. ARM, Xiaomi requires a different approach to installing compilers and libraries than standard ones. x86-system.
Before you start installing heavy IDEs, you need to make sure that your device is ready to work in debugging mode. Redmi Note 8 Pro has 6 or 8 GB of RAM, which is enough to work with lightweight environments, but requires competent resource management so that the MIUI system does not “kill” the background compilation processes.
Preparation of the operating system and unlocking the loader
The first step to creating a development environment is to get advanced file system access rights. The standard MIUI shell aggressively manages memory, which can interrupt the execution of compilation scripts. You will need to activate the developer mode by going to Settings → About Phone → MIUI version and quickly pressing 7 times on the build number.
After activating the hidden menu Advanced settings → For developers, you need to enable debugging over USB. However, to fully work with system partitions, you often need to unlock the bootloader, which allows you to install custom recaps and get root rights. Unlocking the bootloader on Xiaomi devices requires submitting an application through the official Mi Unlock website and waiting for 7 to 168 hours.
⚠️ Warning: Unlocking the bootloader will result in the complete removal of all data from the device. Be sure to back up important designs and settings before starting the procedure, as it will be impossible to restore them without a backup.
To perform unlock operations, you'll need a computer with the Mi Unlock Tool installed. The process syncs the Mi Account to the device, and only after the wait timer has expired will you be able to unlock the bootloader. This is a critical step if you plan to use Magisk for modular system management.
Installation of the Linux terminal and base environment
The most powerful solution at the moment is the Termux app, which provides a terminal emulator along with its own package manager. Don't download the version from Google Play, as it's no longer updated; use the F-Droid repository or the official GitHub release.
Once Termux is installed, you need to update the repositories and install the basic packages. Enter pkg update && pkg upgrade to update the packet lists. To run the compilers, you need clang, make, cmake and git packages. It takes a few minutes to install depending on the speed of the Internet connection.
pkg install clang make cmake git python nodejsIt is important to understand the difference between standard Linux and Android: there are no system directories like /bin or /usr as usual, all files are stored in /data/data/com.termux/files. So the paths to libraries and executables will be different from those you are used to on desktop distributions.
💡
Use the Termux:API plugin to access the phone’s hardware features (camera, GPS, battery) straight from the command line, which is useful for script testing.
Configure code editors and IDEs on a mobile device
Choosing a code editor is a matter of personal preference, but on a mobile device, performance and plug-in support are important. One of the best solutions is Acode, a lightweight but powerful editor with syntax backlighting for dozens of languages and a built-in terminal.
For more complex projects that require a full IDE, you might consider running VS Code through a server infrastructure or using cloud solutions. However, native applications such as Spad or QuickEdit+ show excellent performance on the Helio G90T processor. They support large files and have easy navigation on the project.
- 📱 Acode: Perfect for Web Development (HTML, CSS, JS) and scripts, supports plugins.
- 💻 Spad: Supports C++, Python, has a built-in compiler and debugger.
- ☁️ GitHub Codespaces: Allows you to run a full-fledged VS Code in the browser using the power of the cloud.
Ergonomics are critical when working with code on a smartphone screen: connecting an external Bluetooth keyboard and mouse turns the Redmi Note 8 Pro into a mini laptop. A 1080×2340 screen allows you to comfortably display about 40-50 lines of code, which is enough for mobile development.
☑️ Workplace setting
Compilation and launch of projects on Android
Running a code compilation directly on the device requires the correct setting of paths and environment variables. In Termux, you can compile programs in C/C++ using clang or run scripts in Python and Node.js. Java/Kotlin is more difficult, since a full JDK requires significant resources, but using dx or d8 allows you to compile Android bytecode.
Consider an example of building a simple Python server that can backend your application. Create a server.py file and write a simple one. HTTP-Server. Run by python server.py, after which the server will be available on localhost within the Termux network or even on Wi-Fi if you configure port spreading.
| Programming language | Installation team at Termux | Launch team | RAM consumption |
|---|---|---|---|
| Python 3 | pkg install python | python script.py | Low. |
| Node.js | pkg install nodejs | node app.js | Average. |
| C++ (Clang) | pkg install clang | ./program | Very low. |
| Ruby | pkg install ruby | ruby script.rb | Average. |
Importantly, large projects can take longer to compile than on a PC, due to differences in processor architecture and disk I/O speed. However, the Redmi Note 8 Pro has more than enough power to train, prototype and write microservices.
⚠️ Warning: Long-term compilation of heavy projects causes a strong heat of the processor.Use external cooling or smartphone cooler to avoid trottling (decreased performance due to overheating).
Debugging applications and working with ADB
Android apps require the ability to use Android Debug Bridge (ADB) to develop fully. Although ADB is usually run on a computer to debug your phone, Termux can install an Android-tools package that allows your phone to control another Android device or even yourself (if there is a root).
Tools are installed via pkg install android-tools, and then you can access adb and fastboot commands. APK-files, take screenshots, read system logcats and monitor performance in real time.
adb logcat | grep "MyAppTag"Using logcat on your device is a powerful tool for finding bugs inruntime. You can filter logs by tags, priority and application package. On the Redmi Note 8 Pro, with its large amount of RAM, the log buffer is large enough to track the chain of events that led to the crash of the application.
ADB Secrets on Android
Optimizing the system for the work of the developer
MIUI is known for its aggressive power saving policy, which can kill a compilation process or a running server in the background. To avoid this, you need to set up autostart and work in the background for Termux and your code editor. Go to the battery settings and select No Limits mode.
It is also recommended to disable MIUI optimization. In the Developer Menu, find the item "Enable MIUI Optimization" and turn it off. This action may require confirmation via ADB if the item is hidden.
- 🔋 Battery: Set a charging limit (if there is support through the kernel or Magisk) so that the battery does not swell when running long from the network.
- 📉 Animations: Reduce the scale of animations in the developer settings to 0.5x speed up the interface.
- 🔒 Security: Turn off Memory Cleanup in the background for working applications.
The stability of the development environment depends on free memory. Regularly clean the Termux cache and remove unused packets with the pkg uninstall command. Redmi Note 8 Pro does well in multitasking, but overflowing storage can lead to compilation errors.
💡
The main secret of success is the correct configuration of power management in MIUI, without which no background compiler will not live longer than 10 minutes.
