From Android's perspective, of course it isn't coincidence. Google implemented those APIs that they thought would be useful to Android developers. But from Java's perspective it is coincidence. If I have a Java application or a library (designed for SE or ME -- doesn't matter), it will only work on Android if I'm lucky (I'm not saying there's a 10% chance of it working, but it isn't 90% either). As a maintainer of several Java libraries -- none work on Android -- I feel this pain when people ask us to support Android, and there's a lot of work involved in making that happen.
