CustoMIUIzer A13

简体中文 | English

CustoMIUIzer A13 customizes the system UI and interactions on MIUI 14 / Android 13, with capability-based compatibility paths for HyperOS 1 / Android 13. It uses an independent package, release line, and modern libxposed API.

Maintenance status

Active development has ended as the maintainer has moved to other systems. The project remains available as a stable maintenance build for MIUI 14 / Android 13. Future updates, if any, will be limited to critical fixes, necessary compatibility work, or actual maintainer needs.

Core Features

  • Status-bar clock, date, temperature, network speed, battery, signal, and icon layout;
  • Control center, notifications, volume, brightness, lock screen, media, and charging UI;
  • Launcher icons, folders, Dock, recents, gestures, and animations;
  • Navigation keys, button actions, power menu, floating windows, multi-window behavior, installer, sharing, and app permissions.

Compatibility

Item Supported range
Primary system MIUI 14 / Android 13
Capability-detected target HyperOS 1 / Android 13; feature availability depends on the ROM and system-app versions
SDK minSdk 33 / targetSdk 34
ABI arm64-v8a
Xposed framework LSPosed / Vector
Module metadata minApiVersion=101, targetApiVersion=102, staticScope=false

Android 14 and later are not supported. Do not enable this module together with upstream or another CustoMIUIzer-derived module.

Known deployed baseline: Redmi Note 11T Pro (xaga), MIUI V14.0.10.0.TLOINXM.

Runtime Architecture

  • SystemUI, Launcher, system_server, and regular-app entry points are routed to process-specific Installers, avoiding unrelated installation paths in the wrong process;
  • Features use stable identities, process scopes, install phases, and install-once state; disabled or incompatible features skip unrelated registrations and object creation;
  • ROM Contracts, Resolvers, and Installers share the resolved target, while missing targets safely skip only the affected feature;
  • Receiver, Observer, View, and controller lifecycles are owner-bound with replacement, stale-state, and release paths;
  • Ordinary ROM, reflection, and callback failures remain isolated, while OutOfMemoryError, ThreadDeath, and VirtualMachineError are not disguised as compatibility failures;
  • DeviceInfo and Launcher hot paths reduce repeated Binder calls, reflection, I/O, configuration reads, and temporary objects.

See CHANGELOG_EN.md for release changes and AGENTS.md, ARCHITECTURE.md, COMPATIBILITY.md, and docs/A13_PARITY.md for engineering rules, architecture, and compatibility.

r13.12.2 supersedes r13.12.0 / r13.12.1. This final release adds USB default mode, installer purify, Launcher dock height, hiding the IME dismiss button, status-bar visual options, folder-blur disable, Backup V2 with legacy restore, BatteryIndicator custom colors, and dim-ratio adjustment, and fixes MultiAction / gesture persistence, spinner OOB, Launcher restart scope, USB replug latch, app/shortcut/Activity result relay, and final MultiAction result delivery.

Development notes

  • Stability and behavior preservation come first; compatibility logic stays at ROM / ClassLoader boundaries;
  • Hot-path hooks avoid temporary arrays, collections, regex, formatting, repeated reflection, and remote preference reads;
  • Java-to-Kotlin migrations are behavior-equivalent and gated by tests;
  • MainModule.java, XposedHelpers.java, and MemberUtilsX.java remain the JVM / framework boundary;
  • Fine-grained history lives in Git commits and tags; release changes are in CHANGELOG_EN.md.
