It's true that you can use the NDK to write "Parts" of the app but, don't get me wrong, I don't think it's intended as a replacement for Java or the Java libraries (unless you are writing a game that requires high performance requirements). I think Java is a decent programming language and Android comes with tools nicely integrated in Eclipse IDE. I quote: "The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications. Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. This can provide benefits to certain classes of applications, in the form of reuse of existing code and in some cases increased speed."
