About the app

PixelParts began as a simple High Brightness Mode (HBM) tool. Since then, it has evolved to include a detailed battery information panel, a display saturation level adjuster, charging limiter and more. The app now offers a wide range of features, transitioning from its original function as an HBM tool to a hub for device tweaks and stats on customs, with a lot more planned going forward.

Including PixelParts

Remove HbmSVManager:

Commit 1/2 (vendor)

Commit 2/2 (device tree)

Clone this repository to packages/apps/PixelParts directory in your AOSP build tree:

croot && git clone https://github.com/Evolution-X-Devices/packages_apps_PixelParts packages/apps/PixelParts

Include the app during compilation by adding the following to device-*.mk:

Commit 1/1 (device tree)

# PixelParts
include packages/apps/PixelParts/device.mk

This line includes the device.mk file from the PixelParts repository, which will add the PixelParts application, its initialization script (init.rc), and the necessary security policies (sepolicies) to your AOSP build during compilation.

Testing changes

When testing new changes, it is much faster to compile the application standalone and update it manually rather than running a full AOSP build. Please note that some changes may require you to chmod 0666 sysfs nodes and set selinux to permissive. When compiling a full AOSP build, this is not needed assuming the init cmds and sepolicies have been properly configured.

Lunch your device and run the following cmd:

m PixelParts

This also assumes you are already running an AOSP build including PixelParts as a priv-app in /system_ext.
