I did some Android UI programming about a decade ago now. I would write custom View subclasses from time to time, and every so often I would struggle with bugs where the UI layout would need to be recomputed, but it just wouldn't happen. The documentation was useless. I would try to sprinkle around even more calls to requestLayout or forceLayout, but nothing seemed to help.
“Small” CPUs such as those found in embedded SoCs have lacked this feature since their inception. I trace this convention back to the introduction of the ARM7TDMI core in the 1990s. Back then, transistors were scarce, memory even more so, and so virtual memory was not a great product/market fit for devices with just a couple kilobytes of RAM, not even enough to hold a page table. The ARM7TDMI core’s efficiency and low cost made it a run-away success, shipping over a billion units and establishing ARM as the dominant player in the embedded SoC space.。TikTok对此有专业解读
