How to create and configure an SA:MP server on Android: a complete guide with instructions

Running your own server San Andreas Multiplayer (SA:MP) on a smartphone running Android is a task that seems impossible only at first glance. Many players mistakenly believe that hosting a game server requires a powerful PC or VPS, but modern mobile devices (especially those with processors Snapdragon 8 Gen 2+ or Dimensity 9000+) can cope with this task. Of course, we are not talking about a server for 500 players with hundreds of mods - but for testing scripts, playing with friends or a small community, a smartphone is ideal.

In this guide we will cover all stages: from choosing a suitable hosting application to fine-tuning server files and solving common errors. You will learn how to bypass the limitations of the mobile OS, optimize resource consumption, and even set up remote server management via SSH. Important: the process will require you to have basic knowledge of working with console commands and the Android file system, but we tried to make the instructions as accessible as possible even for beginners.

Before you start, check whether your device meets the minimum requirements:

Device requirements and preliminary preparation

Not every smartphone is suitable for running the SA:MP server. The main limitations are related to performance i access to the file system. Here are the key parameters that are worth paying attention to:

• 📱 Processor: 8-core chip with a clock frequency of 2.2 GHz (recommended Snapdragon 855+, Exynos 2100, Dimensity 1200+). Budget chips like Helio G96 may not be able to handle even 10 players.
• 🧠 RAM: minimum 6 GB (8 GB and higher for servers with 15+ players). Android reserves part of the memory for the system, so at least 3-4 GB should remain free.
• 🗃️ Memory: 5 GB of free space on the internal storage (server files + cache). The memory card microSD is not suitable due to low read/write speed.
• 🔌 Power: the server will actively consume battery power. It is ideal to connect the device to the network or use Power Deliverycharging at 18W+.
• 🌐 Network: stable connection to Wi-Fi 5/6 or mobile data with low ping. 4G can fail due to unstable speed.

In addition to hardware, you will need:

• 🔓 Root access (optional, but greatly simplifies setting up ports and autostart). Without root access, you will have to use workarounds.
• 📂 File manager with access to root folders (for example, FX File Explorer or Solid Explorer).
• 🔧 Terminal to execute commands (Termux is the best choice).

⚠️ Attention: Running a server on a smartphone can lead to device overheating and accelerated battery wear. Do not leave your phone unattended for a long time in server mode, especially if it is not connected to charging.

If your device meets the requirements, you can proceed to installing the necessary software. Let's start by choosing a hosting application.

Choosing an application for hosting the SA:MP server

There is no official client for running the SA:MP server on Android, but there are alternative solutions. We will look at three main options, each of which has its own pros and cons:

Application	Advantages	Disadvantages	Complexity of setup
Termux + SA:MP Server	Full control, support for all mods, low consumption resources	Requires knowledge of Linux commands, manual configuration of ports	⭐⭐⭐⭐
GTA SA:MP Server Launcher	Simple interface, built-in config templates, auto-update	Limited functionality, possible lags on weak devices	⭐⭐
PocketMine-MP (alternative)	Optimized for mobile devices, easy installation, plugin support	Not fully compatible with SA:MP, limited customization options	⭐⭐⭐

For most users, the optimal solution would be Termux this is a terminal emulator for Android that allows you to run Linux applications. It gives maximum flexibility, but requires more effort to configure. If you are a beginner, start with GTA SA:MP Server Launcher —it offers ready-made presets and a visual interface.

We will use Termux, since this is the most universal solution. Install it from F-Droid (the version from Google Play is outdated and does not support all commands).

Update packages (pkg update && pkg upgrade)|

Install dependencies (pkg install wget tar gzip)|

Download SA:MP server files (wget https://sa-mp.com/download.php?file=sa-mp-0.3.7-server-linux.tar.gz)|

Unpack archive (tar -xzvf sa-mp-0.3.7-server-linux.tar.gz)|

Go to the folder with the server (cd sa-mp037)|-->

Installing and configuring server files

After installing Termux and downloading the server files, you must perform the initial setup. Follow the instructions step by step:

1. Unpacking and preparing files:

Open Termux and execute the commands from the checklist above. After unpacking the archive, you will have a folder sa-mp037 with key files:

- samp03svr — executable file server;

- server.cfg — main configuration file;

- gamemodes/ — folder with game modes;

- filterscripts/ — folder for additional scripts.

2. Editing server.cfg:

Open the configuration file in a text editor (for example, via nano server.cfg). Pay attention to the following parameters:

rcon_password your_password // Password for remote control (be sure to change!)
port 7777 // Server port (default 7777)
maxplayers 16 // Maximum number of players
gamemodetext "My Android Server" // Server name in the list
mapname "San Andreas" // Map name
announce 1 // 1 - the server is visible in the master list, 0 - hidden

3. Setting up the game mode:

By default, the server starts without game mode. Copy the file gamemodes/example.pwn to gamemodes/yourmode.pwn and edit it. To compile the script you will need Pawn Compiler, which can be installed in Termux:

pkg install pawn-compiler
pawncc gamemodes/yourmode.pwn -o gamemodes/yourmode.amx

⚠️ Attention: If you use public IP (not a local network), be sure to change rcon_password and configure firewall on the router. An open server with default settings can be hacked within hours.

4. Starting the server:

Go to the server folder and run the command:

./samp03svr

If everything is configured correctly, you will see the startup log with the message Server initialized.

Configuring ports and forwarding on the router

For players to connect to your server, you must open port 7777 (or another specified in server.cfg) on the router. Without this, the server will only be accessible on the local network. The instructions depend on the model of your router, but the general algorithm is as follows:

1. Find the local IP of your device:

In Termux run the command:

ifconfig

Look for the line inet addr: in the section wlan0 (Wi-Fi) or rmnet_data (mobile data). For example, 192.168.1.105.

2. Enter the router settings:

Open the browser and enter the router address (usually 192.168.1.1 or 192.168.0.1). The login and password are indicated on the device sticker.

3. Configure Port Forwarding:

Find the section Port Forwarding, NAT or Virtual servers. Add a new rule:

• 🔢 Service name: SA:MP Server
• 🔢 Port start/end: 7777 (or your custom port)
• 🔢 Protocol: TCP and UDP
• 🔢 Local IP: IP of your smartphone (from step 1)
• 🔢 Local port: 7777

4. Check external IP:

Find out your public IP through a service like 2ip.ru. Players will connect to your_ip:7777.

⚠️ Attention: If you have Dynamic IP (changes when reconnecting), use the service No-IP or DynDNS to link the domain name. Without this, players will lose access to the server after changing IP.

5. Checking the connection:

Ask a friend to connect to your server via the SA:MP masterlist or directly via IP. If the connection is not established, check:

• 🔌 Correct port forwarding;
• 🔥 Firewall settings on the router and smartphone;
• 📡 Stability of the Internet connection (ping to the server should not exceed 100 ms).

What to do if the port does not open?

If the port remains closed after forwarding, try:

1. Disable UPnP in the router settings (sometimes it conflicts with manual rules).

2. Check if the port antivirus on your smartphone is blocking (disable it temporarily).

3. Reboot the router and device.

4. Make sure that mobile operator does not block incoming connections (relevant for 4G/5G).

Optimizing server performance

Android is not an ideal platform for hosting game servers, but with the right settings you can achieve stable work. Here are the key recommendations:

1. Limiting FPS and streams:

In the file server.cfg add the lines:

fpslimit 30 // Server FPS limit (default 50)
sleep 5 // Delay between ticks (helps reduce CPU load)

For servers with 10+ players, set fpslimit 20.

2. Disable unnecessary modules:

If you do not use file-logging or RCON, disable them:

logtimeformat [%H:%M:%S]
enablelog 0 // Disables writing logs to a file (saves place)

3. Use of lightweight scripts:

Avoid resource-intensive mods like Roleplay with hundreds of objects. Optimal modes for Android: (for up to 15 players); overheating. To reduce the temperature:

• 🏆 Deathmatch (up to 15 players);
• 🚗 Drift/Race (up to 10 players);
• 🎯 Minigames (For example, Hide and Seek).

4. Device cooling:

Long-term operation of the server leads to overheating. To lower the temperature:

• 🧊 Use cooling pad for a smartphone;
• 🔄 Limit the maximum processor frequency via Kernel Adiutor (required root);
• 📉 Close all background applications (especially instant messengers and games).

Remote control and autostart of the server

Starting the server manually every time is inconvenient. Fortunately, there are ways to automate the process and manage it remotely.

1. Autostart when the device is turned on:

In Termux install the package termux:boot:

pkg install termux:boot
mkdir -p ~/.termux/boot
echo 'cd /sdcard/sa-mp037 && nohup ./samp03svr &' > ~/.termux/boot/start_samp

Now the server will start automatically when booting smartphone.

2. Management via SSH:

Install OpenSSH in Termux:

pkg install openssh
ssh-keygen -t rsa // Create SSH keys
passwd // Set a password for the user

Connect to the server from a PC via ssh your_ip -p 8022 (the default port in Termux is 8022).

3. Monitoring via RCON:

If server.cfg enabled rcon, you can manage the server via console commands. Examples:

rcon password your_password
rcon say Hello, players!  // Send a message to all players
rcon kick 0 // Kick player with ID 0

4. Backup configurations:

Regularly save copies of files server.cfg and gamemodes/ to the cloud (for example, via rclone in Termux). This will help quickly restore the server after a failure.

Solving common errors and problems

When running a server on Android, you may encounter errors. Let's look at the most common ones and how to fix them:

Error	Cause	Solution
Failed to bind socket (address already in use)	Port 7777 is occupied by another application	Change the port in server.cfg or find the process occupying the port (netstat -tuln)
Segmentation fault	Corrupted server files or lack of memory	Reinstall server files or reduce maxplayers
Server is not visible in the master list	Incorrect port forwarding or blocking by a firewall	Check your router settings and disable the firewall on your smartphone
High ping (lag) for players	Low Internet speed or CPU overload	Limit FPS, close background applications, switch to a wired connection (USB-ethernet)

If the server crashes without errors, check the logs in the file server_log.txt. A common reason is script incompatibility with the mobile version of the server. Test mods one at a time to identify the problematic one.

⚠️ Attention: On some firmware (for example, MIUI or ColorOS) Android aggressively closes background processes. Add Termux to the list of battery optimization exceptions, otherwise the server will turn off after 10-15 minutes.

If the problem is not solved, try:

• 🔄 Restart your smartphone and router;
• 📥 Reinstall server files;
• 🛠️ Update Termux and all packages (pkg update && pkg upgrade).

FAQ: Frequently asked questions about running the SA:MP server on Android

Is it possible to start the server without root access?

Yes, but with limitations. Without root you will not be able to:

• Automatically forward ports on some routers;
• Run a server on ports below 1024;
• Use iptables for fine-tuning the network.

However, the basic functionality (starting the server, connecting players) will work.

How many players can the server support on a smartphone?

Depends on the hardware:

• Flagships (Snapdragon 8 Gen 2+, 12 GB RAM): 20-25 players in light modes;
• Mid-class (Snapdragon 7xx, 8 GB RAM): 10-15 players;
• Budget devices: 5-8 players (lags are possible).

If the limit is exceeded, the server will start to freeze or crash.

How to make the server accessible via the Internet if I have a dynamic one IP?

Use services DDNS (Dynamic DNS):

1. Register on No-IP.com or DynDNS.com;
2. Create a host (for example, myserver.ddns.net);
3. Set up a DDNS client on the router or in Termux (pkg install ddns-updater);
4. Players will connect by domain name instead of IP.

IP updates occur automatically every 5-10 minutes.

Can I use mods from the server on a PC?

Yes, but not all problems may arise with:

• Mods that require .dlllibraries (they do not work on Android);
• Scripts that use SQLite or other databases;
• Modes with a large number of objects (more 1000).

Test mods one at a time, starting with simple ones (for example, Deathmatch or Race).

How to reduce battery consumption?

The SA:MP server can drain a smartphone in 2-3 hours. To extend the operating time:

• Connect the device to charging (preferably with support) data-i="327">Activate the mode Quick Charge);
• Reduce fpslimit until 15-20;
• Disable Wi-Fi (if you use mobile data) or vice versa;
• Activate mode Battery in the Android settings (it will limit background activity).

The ideal option is to run the server on a smartphone connected to Power Bank.
