Android Developers Blog: Now available: Android 1.6 NDKAndroid 1.6 NDK, release 1 is available for download from the Android developer site.
To recap, the NDK is a companion to the SDK that provides tools to generate and embed native ARM machine code within your application packages. This native code has the same restrictions as the VM code, but can execute certain operations much more rapidly. This is useful if you're doing heavy computations, digital processing, or even porting existing code bases written in C or C++.
