Google Provides Android Coders the Native Development Kit
Google recently made the native development kit for Android version 1.5 available to those writing applications for the Android platform. The NDK will give some developers another avenue to approach how they create applications for Android, and will include things such as compatibility with C and C++. This set of tools isn't for all applications, but might help some developers make better use of signal processing and data processing. Anything developed using NDK 1.5 will be compatible with Android 1.5 and future versions of Android, too.
