How to create a SAMP server on Android: step-by-step guide

Mobile gaming has long ceased to be just entertainment for short trips on the subway. Modern smartphones have the computing power that allows you to run full-fledged game servers right in your pocket. Creating your own project SA-MP (San Andreas Multiplayer) based on Android is not only a way to play with friends, but also an excellent practice for those who want to understand the architecture of game worlds and scripting.

Unlike classic deployment on a VPS or dedicated server, the mobile platform imposes its own limitations, but also opens up unique opportunities for testing and training. You don't need to rent expensive equipment or set up complex network infrastructure from scratch. It is enough to have a device on hand Android and the desire to dive into the technical part of modding.

However, it is worth noting right away that the process requires attention to detail. The operating system Android was not originally intended for hosting server applications, so we will have to use specialized tools for emulating the Linux environment. This will allow you to launch the native server binary file, which usually runs on desktop operating systems.

Required tools and environment preparation

The first step is to install basic software that will create the foundation for the server to operate. The main tool will be a terminal emulator, which will allow you to run commands from a Linux-like system directly on your device. Without this component, launching the server executable file is impossible, since the standard Android shell does not support the necessary libraries.

For comfortable work, you will also need a file manager with extended access rights to move archives and edit configuration files. It is important that your device has a sufficient amount of free RAM, since compiling and running the server are resource-intensive processes. Minimum requirements for hardware may vary, but having at least 4 GB of RAM will make the task much easier.

⚠️ Warning: Using terminal emulators can consume a significant amount of power and cause the device to heat up. It is recommended to carry out the setup with the charger connected and in a well-ventilated place.

The list of required software includes not only an emulator, but also a text code editor, since you will have to make edits to the scripts. Many users prefer to use the built-in terminal capabilities for editing, but having a separate application for working with code increases convenience and reduces the risk of syntax errors when typing commands.

• 📱 Termux - terminal emulator and Linux environment for Android, the main tool for running the server.
• 📂 ZArchiver or a similar archiver for unpacking SA-MP server source codes and libraries.
• ✏️ Acode or QuickEdit —text editors for editing configuration files server.cfg and scripts.
• 🌐 Stable Wi-Fi connection —for downloading packages and ensuring low latency when connecting players.

Installing and configuring Termux

After installing the Termux application from a trusted source (it is best to use F-Droid or the official GitHub repository, since the version on Google Play is often out of date), you need to update the package lists. This is standard procedure for any Linux system and ensures that you install the latest versions of dependencies and avoid library conflicts.

Enter the command pkg update && pkg upgrade and confirm the action. This process may take some time depending on the speed of your Internet connection. After updating the base packages, you should install the compiler clang, which is necessary to build the server module from source code. Without a compiler, starting the Pawn script engine will be impossible.

Next, install the necessary utilities with the command pkg install git clang wget. The utility git will be needed to download source codes, and wget to download ready-made server binary files, if you do not plan to compile them manually. Creating the correct file structure is also important: create a separate directory, for example mkdir samp-server, and go to it with the command cd samp-server.

It is important to give Termux access to the device storage by running the command termux-setup-storage. This will allow you to easily transfer configuration files and mods from the phone's internal storage to the server folder without using complex network protocols. After confirming access, a folder will appear in the system storageassociated with your phone files.

Downloading and installing SA-MP server files

Now you need to get the server files themselves. The official SA-MP server is distributed as an archive containing an executable binary for Linux. Since the architecture of processors in smartphones (usually ARM) differs from standard server ones x86_64, you will need to either find a special ARM version of the server, or use emulation, or (which is most effective) compile the server yourself for your architecture.

If you are using a ready-made binary, download it using wget via a direct link. After downloading the archive, unzip it. Inside you will find an executable file sanandreas (or samp037 depending on the version) and a folder pawno with scripts. Make sure that the executable file has permissions to run using the command chmod +x sanandreas.

File/Folder	Destination	You need to edit
server.cfg	Main server config (name, max. players, mode)	Yes (required)
gamemodes/	Folder with game modes (.amx files)	Optional
plugins/	Additional modules (MySQL, sscanf, etc.)	Depends on the mod
scriptfiles/	Data files (accounts, houses, cars)	No

The critical file is server.cfg. It is in it that the parameters that the player sees when connecting are written down. Open this file in a text editor and find the line gamemode. Make sure that the specified game mode file name matches the file in the folder gamemodes. Also check the line rcon_password —this is the administrator password, which should be complex.

Problem with the glibc library

If you get an error related to glibc when starting, it means that the standard version of the server is not compatible with Android. You will need to use a special patch or an emulator like proot-distro to create a compatible environment.

Compiling a game mode (optional)

Standard game modes often require modification or complete rewriting to suit the needs of your project. The Pawn language is used to make changes to the game logic. You will need a compiler pawncc, which can be installed in Termux via a package manager or downloaded as a static binary. Compilation allows you to turn the source code (.pwn) into an executable file (.amx) that the server can understand.

The compilation process is as follows: go to the folder with the sources and run the compilation command. For example: pawncc mymode.pwn -o gamemodes/mymode.amx. If there are no syntax errors in the code, you will receive a completed mode file. This gives flexibility in creating unique systems that are not possible in standard assemblies.

During compilation, errors may occur due to missing include files. Make sure that the folder pawno/include contains all the necessary libraries, such as a_sampdb, sscanf or streamer. Without these header files, the compiler will not be able to understand the functions used in the code.

• 🔍 Syntax check: Always read the warnings in the console carefully before compiling.
• 💾 Backup: Save the original .pwn files before making edits.
• 🧩 Plugins: if the mod uses plugins, make sure that their .so files are also adapted for ARM architecture.

Starting the server and debugging

After all the files are in place and The configuration has been verified, you can proceed to launch. In the Termux terminal, while in the server folder, enter the command ./sanandreas (or the name of your executable file). If everything went well, the loading logs will appear in the console: "Loading gamemode...", "Number of vehicle models: ...".

If the server has started, but you cannot connect, check your Android firewall settings. The system can block incoming connections to the server port (default 7777). Also make sure you are using the correct IP address. For a local connection on the device itself, this is 127.0.0.1, but to play with friends you will need your external IP or port forwarding settings on the router.

During operation, the server may crash due to lack of memory or errors in scripts. Watch the terminal output: red lines usually indicate critical errors. A common problem on Android is limiting background activity - do not minimize Termux completely, otherwise the system may “kill” the server process to save battery power.

⚠️ Attention: Interfaces and power saving settings in Android are constantly changing by manufacturers (Samsung, Xiaomi, Huawei). If the server turns off when the screen is off, find the Termux application in the battery settings and select the “Unlimited” mode.

Organizing access for other players

So that friends who are on another Wi-Fi network or via the mobile data can access your server, simply launching it is not enough. Your phone is behind a NAT router, and the outside world does not see the open port. There are two main solutions: Port Forwarding or using tunnels.

Port forwarding requires access to the admin panel of your router. You need to find the Port Forwarding section and create a rule: external port 7777 -> internal IP of your phone -> internal port 7777. Select UDP (sometimes TCP/UDP) protocol. After this, your external IP address will become available for connection from anywhere in the world.

An alternative and often easier way for mobile devices is to use apps for creating a virtual local network, such as Hamachi or Radmin VPN. In this case, all players must install the same application, create a group and connect to it. Then the server will be accessible via the internal IP address issued by the tunnel app.

Don't forget about safety. By opening ports, you are potentially exposing your device. Use strong RCON passwords and update your antivirus software regularly. It is also worth limiting the maximum number of players (parameter maxplayers) so as not to overload the phone's processor, which can lead to lags and connection breakdowns.

Frequently asked questions (FAQ)

Is it possible to run the SA-MP server version 0.3.7 on Android?

Yes, this is possible, but it requires searching for specific binary files adapted for the ARM architecture, or independently compiling the source code of this version. Most ready-made assemblies on the network are focused on version 0.3.DL.

Why does the server crash immediately after startup?

The most common reasons: lack of rights to execute the file (solved through chmod +x), incompatibility of libraries (glibc), syntax error in server.cfg or lack of RAM. Check the logs in the terminal for an accurate diagnosis.

Do you need Root to create a server?

In most cases, root access is not required if you use Termux. However, for forwarding ports below 1024 or deep network configuration, superuser rights may be required. Standard port 7777 works without Root.

How to save server data after rebooting the phone?

The SA-MP server saves data (accounts, houses) to text files in a folder scriptfiles automatically when turned off or on a timer. The main thing is not to delete the Termux folder and make backup copies of important files manually.

Is it possible to run a MySQL database on the phone along with the server?

Yes, you can install the package mariadb or mysqlin Termux. However, this will greatly increase resource consumption. For simple projects, it is better to use file databases or lightweight alternatives, and for large ones, move the database to external hosting.
