A1 memory management

A1 Memory Management represents an innovative third-party tool aimed at optimizing memory usage on rooted Android smartphones. This module focuses on enhancing device performance by intelligently handling background applications, minimizing unnecessary process terminations, and freeing up non-critical resources automatically. It integrates smoothly with root frameworks like Magisk or KernelSU, allowing it to coexist with other optimization tools without causing interference. By leveraging low-level system hooks, it provides a lightweight solution that enters a low-power state during device idle times, ensuring minimal impact on battery life.

Developed by OneB1ank, this module appears in version Richard8, released on November 26, 2023. It supports various rooting methods such as Magisk, KSU, APatch, and KSUNext, making it accessible for a wide range of users in the modding community. As a popular choice, A1 Memory Management builds on efficient C/C++ code from the HAMv2 framework, offering features like app hibernation and customizable rules for process management. Although the repository is now archived as of January 10, 2024, it remains a reliable option for those seeking better memory control on older Android versions. The project’s open-source nature under GPL-3.0 encourages exploration of its code, including configuration files for tailored adjustments.

Key Features

Effective control over background processes to manage their persistence and shutdown.
Ability to target and release specific subprocesses within apps.
Blocking of the Low Memory Killer Daemon to avoid abrupt app closures.
Automated liberation of unused memory segments.
Hibernation mode for applications to lower CPU and RAM consumption.
User-friendly terminal interface for enabling or disabling options, accessible through commands like amui.
JSON-driven customization for detailed parameter tweaks.
Intelligent rule sets, such as KILL directives for precise package and subprocess handling.

Installation Guide

To install A1 Memory Management, confirm your device runs Android 8.0 to 14 and features arm64-v8a architecture, with Magisk v20.4 or higher (or compatible KSU) as the root method. Download the ZIP file from the GitHub releases page. Open the Magisk Manager app, navigate to the modules section, and select the downloaded package for installation. Reboot the device to activate the module. After setup, the default configuration file will be placed at /sdcard/Android/HChai/HC_memory/名单列表.conf for initial adjustments. For advanced users, edit the memory.json at /data/adb/modules/Hc_memory/config/memory.json to fine-tune settings. Launch the terminal UI by running terminal.sh via Termux or MT Manager, using arrow keys for navigation and Enter to apply changes.

Functionality and Usefulness

Functionally, A1 Memory Management operates by integrating into Android’s memory system through scripts that handle setup and runtime tasks. The module.prop file defines essential metadata like the module’s name, version, and author, serving as the identifier for root managers during installation. The customize.sh script likely manages post-installation customizations, such as setting permissions or creating directories for configurations. Service.sh oversees background operations, including monitoring processes and applying hibernation rules, while magisk.sh acts as the primary bootstrap script to initialize the environment and load JSON configs on boot. Terminal.sh provides an interactive UI for toggling features, located at /sdcard/Android/HChai/HC_memory/terminal.sh, allowing users to adjust settings via simple commands. These scripts collectively hook into system mechanisms using the HAMv2 framework, enabling features like LMKD blocking and memory release without high overhead, as the module sleeps during standby to conserve resources.

The usefulness of A1 Memory Management shines in scenarios where devices suffer from aggressive background killing or limited RAM, making it ideal for users on mid-range or older hardware. It enhances multitasking by preserving important apps, reduces lag from frequent reloads, and improves overall responsiveness, which is particularly beneficial for gamers, multitaskers, or those running resource-intensive software. By offering customizable whitelists and hibernation, it allows privacy-focused tweaks, such as preventing unnecessary data usage in idle apps, while its compatibility with other modules enables layered optimizations. This tool extends device usability, supports educational exploration of Android internals, and provides a reversible way to experiment with system tweaks, ultimately helping users achieve a more efficient and personalized mobile experience without permanent modifications.

Compatibility Details

A1 Memory Management is designed for Android versions 8.0 through 14, exclusively on arm64-v8a architectures, ensuring it runs on most modern 64-bit devices. It integrates well with Magisk starting from v20.4 and offers partial support for KSU, with broad compatibility across APatch and KSUNext as well. The module avoids conflicts with other Magisk or Xposed tools, allowing cumulative use for enhanced effects. However, Samsung devices may encounter forced background mode when LMKD prevention is active, requiring users to disable that specific hook. Audio playback interruptions are rare but can be mitigated by adding processes to whitelists. It does not counter manufacturer-specific killers, and non-arm64 setups will fail with incompatibility errors. Custom ROMs may yield better results, but testing on stock firmwares is recommended for stability.

Additional Notes

Users should note the repository’s archived status, meaning no future updates, but existing versions remain functional. For troubleshooting, refer to the changelog.md for version-specific fixes or JSON-CONFIG.md for detailed configuration guidance. Warnings include careful use of KILL rules to prevent app malfunctions and awareness that OEM killers bypass LMKD blocks. Power usage is low thanks to optimizations, and features like smart lists require proper syntax. Credits go to contributors like yc9559 and HChenX for code, with testing by 火機@coolapk.
