Hard to attribute that to GC.

• iainmerrick 10y ago
  Why hard? On Android, the GC will print a log entry telling you how long it took! In my experience, aside from badly-written algorithms that just do too much work on the wrong thread, the main causes of momentary glitches are GC and I/O. Unfortunately you have limited control over those in application code (just using too much memory can cause some I/O churn). On mobile, the GPU drivers are often badly written and will give you random hiccups that can ultimately be traced back to I/O. Not to turn this into an Apple vs Android battle, I hope, but I think this is an important point that is often overlooked -- Apple's hardware and software designs are really well-targeted to minimize those kind of glitches. They don't use GC and they always use very fast (AKA expensive) flash memory. So whatever else their flaws, Apple devices tend to have smoothly-animated UIs.
