Dalvik VM has been the default VM since first Android versions.
Google released the new ART runtime in KitKat 4.4.
From what I understood, Dalvik VM translates dex bytecode into machine instructions in runtime. ART precompiles dex code into native instructions, so that it eliminates runtime translation step.
With respect to this:
- Is my understanding accurate?
- If ART compiles dex bytecode into native, what happens to Garbage Collector?
- Is the idea behind ART somehow similar to Microsoft’s NGEN?
- How would ART impact app debugging?
