There is one thing that I does not understand with this NDK, as I understand it, it would not run directly on the CPU on the device, but rather in some kind of emulated mode.

They (Android Team) says “If you write native code, your applications are still packaged into an .apk file and they still run inside of a virtual machine on the device” on their page http://developer.android.com/sdk/ndk/index.html

The reason I wounder is that I’m really not an Java-programmer, Last time I wrote some Java code I was 10yrs old
