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):
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)
