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.
Wait, thats is very different from what I read back in the day. I know there was a point at, I dunno, android 5 where they started doing something different with java, but my impression was that android always ran a JVM of sorts. And frankly, given how it performs even on the highest-end devices, that was really easy to believe.
I guess I need to do some research now.
Pretty sure it was Dalvik virtual machine that Java was compiled to byte code for before 4.4 when they deprecated Dalvik for Android Runtime (ART), fully dropping Dalvik in 5.
@fartsparkles @Sheltac Android always ran dalvik bytecode and never Java bytecode
The change to Art was just a replacement of the "VM", but didn't change what byte code was run. It's similar to how Hotspot improved the Java VM while also not fundamentally changing that it's running Java bytecode.
Thank you for the insight!
