I don't know, but remember that Android does not run the JVM, it runs the now deprecated Dalvik or the more modern ART, both Google in house projects.

None of them have all those million engineer hours baked in, not even close.

My guess is that the CLR have more man hours spent on than both those two implementations combined.

This is no longer true.

It is my understanding Android simply uses the class library of OpenJDK. Android will continue to used the ART VM instead of the HotSpot VM.

True, but I personally believe this is the first step to adoption. The whole issue was around licensing..not because the Hotspot vm had something fundamentally missing (zygote and MVM notwithstanding)

That's hard to know and I have no insider knowledge.

From the outside it seems like a lot of work. Firstly HotStop is not optimized for fast startup, small footprint or short GC pauses. There is talk about merging the Java ME VMs but such things usually take years. Secondly Google built many proprietary extensions, eg DEX. I'm not sure that ART can even execute Java bytecodes.
