The Dart &amp; Go teams have projects to target Android but AFAIK these are independent projects with no relation with the Android team.<p>Dalvik -&gt; it is already replaced by ART, but it is still a VM (for ART the bytecode is compiled AOT though).<p>AFAIK, there is no public plan to replace java, neither are there any public commit on AOSP indicating a move in that direction.<p>Many Android devs are following Kotlin very closely (it is a boon for Android app development) but again there is no known plan from the Android frameworks team to switch to it.
