Sure, but my point was about similarity/compatibility. It might be the case that Android has suitable alternatives to Java's features, and it's possible that they're even more suitable for Android's needs, but the point is that while the two platforms were quite similar ten years ago, and a single language could target both with few if any tradeoffs, this is increasingly becoming tenuous as the two platforms become dissimilar in fundamental aspects. A language that attempts that will increasingly find itself needing to make tradeoffs that it didn't need to, say, five years ago, or even today.
