ART doesn't entirely replace Dalvik?

    I keep reading articles about ART replacing Dalvik but, as far as I can determine, the ART Runtime is replacing the Dalvik Runtime, but that Dalvik bytecode (namely dex files) are still being used in ART. It looks as if, at the Dalvik bytecode level, nothing has changed. (There's no such thing as a specific ART bytecode.) Am I correct in my understanding?

    Hmm, not sure if they (the .dex files) are really still used... The snippet of text from the below article implies that they're only needed by the dex2ota tool:

    I'm guessing we're just in a transitory phase where Android is simply keeping the .dex files around for the ability and ease of flipping back and forth between Davlik and ART--but not 100% sure about that :dontknow:.
