Android - Is it possible to run Minecraft on an Android?

Minecraft Pocket Edition is available in the Google Play Store and Amazon's Appstore. Engadget has a hands-on of the game, and "SonyEricssonDev" has a video showing Minecraft being played on the Xperia Play.

I know nothing about Minecraft but I can't see how it would be possible without rewriting big chunks of it. Even if you can convert the JAR to an .apk, there are many Java classes that are not part of the Android API. Furthermore, Android does not include AWT, Swing or Java 2D/3D, it has its own UI and graphics APIs, so the user interface would need to be rewritten.

Android cannot just "run" native Java applications. Android does not have a Java Virtual Machine. Android uses a Dalvik Virtual Machine, which is completely different.

While android applications are written in Java, it is a "subset" of actual Java. so even if you could run the jar files through a "converter", there is no guarantee the code is actually supported by Dalvik.
