Possible explanation for jank in Android as opposed to iOS (20 millisecond core ramp on ARM/Android vs 50 microseconds on Apple/iOS) (social.treehouse.systems)

Interesting, I always thought it had to do with Android’s ungodly software stack which at some point involves, of all things, fucking java.

[–] fartsparkles@sh.itjust.works -2 points 1 year ago (1 children)

Android doesn’t use Java at a byte-code level and never has, as far as I can tell. Source code was written in Java since mobile developers were so used to it but Android never ran the JVM, they do their own thing with Java source.

You can dislike Java syntax but the software stack on Android wasn’t Java’s.

Dalvik/ART is essentially the same idea. It uses dalvik byte code, much in the same way the JVM operates.

There’s some complexity (it’s designed to do different things, and the whole Oracle lawsuits added some wrinkles) but it’s not so different as you imply.

Java is only used for software development, there's nothing Java during run time.

ART?

[–] Aux@lemmy.world 0 points 1 year ago (2 children)

ART what?

[–] huginn@feddit.it 3 points 1 year ago

ART is the equivalent of a JVM. It doesn't implement all the apis, the compiled bytecode differs, it's optimized for mobile but that doesn't make it not a JVM.

That's why the NDK exists: so you can build and run C++ code natively.

Thou art wrong.

I have no experience with iOS but I do develop for the Meta Quest which runs on Android and wow is it jank. One solution for apps up to 2GB and another for up to 4GB and yet another, much more complicated solution for apps over 4GB. Is iOS like this too?

TIL that a microsecond exists and 1 millisecond is the same as 1,000 microseconds.
