# SystemUI Module
|
|
|
|
This directory contains all the required SystemUI modules, based from
|
|
the [upstream source code](https://android.googlesource.com/platform/frameworks/base/+/refs/heads/main/packages/SystemUI/)
|
|
of the SystemUI app.
|
|
|
|
Some examples of modules include [`common`](#common-submodule), which serves as a helper for other
|
|
SystemUI modules, and
|
|
`unfold`, which handles devices with hinges.
|
|
|
|
## `common` submodule
|
|
|
|
`SystemUICommon` is a module that hosts standalone helper libraries. It is intended
|
|
to be used by other modules, and therefore should not have other SystemUI dependencies to avoid
|
|
circular dependencies.
|
|
|
|
To maintain the structure of this module, please refrain from adding components at the top level.
|
|
Instead, add them to specific sub-packages, such as `systemui/common/buffer/`.
|
|
This will help keep the module organized and easy to navigate.
|
|
|
|
## `utils` submodule
|
|
|
|
A stripped-down version to only include the `WindowManagerUtils` code used by `wmshell`.
|
|
|
|
### `viewcapture` submodule
|
|
|
|
> [!CAUTION]
|
|
> `ViewCapture.java` is **extremely performance sensitive**.
|
|
> **Any changes should be carried out with great caution** not to hurt performance.
|
|
|
|
The following measurements should serve as a performance baseline (as of 02.10.2022):
|
|
|
|
1. The onDraw() function invocation time in WindowListener within ViewCapture is measured with
|
|
System.nanoTime(). The following scenario was measured:
|
|
- Capturing the notification shade window root view on a freshly rebooted bluejay device (2
|
|
notifications present) -> avg. time = 204237ns (0.2ms)
