# StatusBarTweak
|
|
|
|
StatusBarTweak is an Xposed/LSPosed module originally built for Samsung
|
|
SystemUI. It focuses on making the status bar, lockscreen, and Always On
|
|
Display more configurable while still keeping the system's own icons and visual
|
|
style where possible.
|
|
|
|
The project is physically tested only on a Samsung Galaxy Z Fold5 running One UI
|
|
8.0 / Android 16. Other SystemUI builds have emulator-tested support as shown
|
|
in the compatibility matrix.
|
|
|
|
## AI Assistance
|
|
|
|
This project was developed with help from AI-assisted coding tools. The design
|
|
decisions, physical device testing, and final behaviour are still manually reviewed.
|
|
|
|
## What It Does
|
|
|
|
- Custom status bar layout for the unlocked screen, lockscreen, and AOD where
|
|
supported by the SystemUI build.
|
|
- Independent placement of clock, carrier text, notification icons, status
|
|
icons, and Samsung status chips.
|
|
- Separate notification display handling for Samsung's cards, icons, and dot
|
|
modes.
|
|
- Configurable icon sizes, vertical offsets, ordering, spacing, truncation, and
|
|
cutout handling.
|
|
- Hide selected notification icons by app, separately for AOD, lockscreen, and
|
|
unlocked mode.
|
|
- Hide selected status icons such as NFC, Bluetooth, hotspot, location, VPN,
|
|
battery, and similar SystemUI indicators.
|
|
- Optional custom clock text with multi-line formatting, colours, font families,
|
|
and cutout-aware split alignment.
|
|
- Battery bar with configurable position, alignment, thickness, colours, and
|
|
threshold colours.
|
|
- Controls for Samsung status chips such as media, navigation, and call chips.
|
|
- Debug tools for generating test notifications, visualizing layout containers,
|
|
and restarting SystemUI during development.
|
|
|
|
## Custom Clock Text
|
|
|
|
The custom clock uses Java-style date/time patterns such as `HH:mm`,
|
|
`EEE d MMM HH:mm`, or `HH:mm:ss`.
|
|
|
|
It also supports lightweight markup:
|
|
|
|
- HTML-like tags: `<i>`, `<u>`, `<small>`, `<big>`, and `<font ...>`.
|
|
- Shorthand blocks such as `{#FA0 big @sans-serif-condensed}HH:mm`.
|
|
- Multi-line text using `\n` or `{\\n12}`; numbered line breaks use statusbar units.
|
|
- Pipe alignment with `|`, useful for aligning split clock rows around a camera
|
|
cutout.
|
|
- Colour variants and reverse Polish notation colour math for light/dark status
|
|
bar states, for example `color(#batterybar 1.2 *RGB ; #batterybar 0.5 *RGB)`, which uses the batterybar's dynamic colour as its base. For the bright tint, it brightens it up some more, while for the dark tint, it is darkened.
|
|
|
|
The in-app clock page has the full syntax help and examples.
|
|
|
|
## Requirements
|
|
|
|
- A rooted Android 14+ device or emulator. Actual feature support depends on
|
|
the SystemUI implementation; see the compatibility matrix.
|
|
- A modern Xposed implementation such as LSPosed or another libxposed-compatible runtime.
|
|
- Xposed API 101 or newer.
|
|
- SystemUI access for the module scope.
|
|
|
|
The module is developed and manually tested on a Samsung Galaxy Z Fold5 running
|
|
One UI 8.0 / Android 16. Non-Samsung builds have emulator-tested support as
|
|
shown below, but hardware-dependent behavior remains experimental unless it has
|
|
also been verified on physical hardware.
|
|
|
|
## Device Compatibility
|
|
|
|
Some behavior cannot be fully verified on emulators. Emulator testing can still
|
|
verify whether hooks load, whether SystemUI stays stable, whether settings apply,
|
|
whether excessive background work appears in logs, and whether the steady state
|
|
looks the way it should.
|
|
|
|
`⚠️ Experimental` means best-effort support exists, but the emulator cannot
|
|
expose the required hardware or state for real verification.

|
Current emulator targets use rooted LSPosed snapshots. They are useful for
|
|
compatibility work, but hardware-specific entries remain marked as experimental
|
|
when the emulator cannot expose the required state.
|
|
|
|
## Build
|
|
|
|
The project is a standard Gradle Android project:
|
|
|
|
```bash
|
|
./gradlew assembleDebug
|
|
```
|
|
|
|
Release builds require local signing configuration:
|
|
|
|
```bash
|
|
./gradlew assembleRelease
|
|
```
|
|
|
|
## Test Harness
|
|
|
|
The repository also includes a small companion app for compatibility testing.
|
|
It is not required for normal use of the module. It creates repeatable
|
|
statusbar scenarios such as opaque, transparent, fullscreen, privacy-indicator,
|
|
and notification states:
|
|
|
|
```bash
|
|
./gradlew :test-harness:assembleDebug
|
|
adb install -r test-harness/build/outputs/apk/debug/test-harness-debug.apk
|
|
adb shell am start -n se.ajpanton.statusbartweak.harness/.MainActivity
|
|
```
|
|
|
|
Automation can launch scenarios directly:
|
|
|
|
```bash
|
|
adb shell am start -n se.ajpanton.statusbartweak.harness/.ScenarioActivity --es scenario fullscreen_landscape
|
|
adb shell am start -n se.ajpanton.statusbartweak.harness/.MainActivity --es command post_normal
|
|
```
|
|
|
|
Useful scenario values include `opaque_light`, `opaque_dark`, `transparent`,
|
|
`fullscreen_portrait`, `fullscreen_landscape`, `camera`, `microphone`, and
|
|
`camera_microphone`.
|
|
|
|
Useful command values include `post_normal`, `post_ongoing`, `post_grouped`,
|
|
`update`, `start_chronometer`, `start_churn`, `stop_churn`, `start_media`,
|
|
`start_foreground`, `stop_service`, and `clear`.
|
|
|
|
Battery charging state is controlled by Android system commands rather than by
|
|
the harness APK:
|
|
|
|
```bash
|
|
adb shell cmd battery set status 2
|
|
adb shell cmd battery set level 80
|
|
adb shell cmd battery reset
|
|
```
