That is basically correct. My understanding is that Jolla phones run an Android runtime, either Dalvik VM or ART, plus the Android Framework code.<p>Had Microsoft taken the approach of running a separate runtime for Android apps instead of trying to map frameworks, they might have something by now.<p>They would still have to map the semantics of the behavior of an app being foreground or not, connect the clipboard, etc. So it&#x27;s not like dropping-in a runtime that&#x27;s meant to be portable, but it&#x27;s a lot closer.
