Today we are releasing an updated version of the Android NDK, now in revision 7. The updated NDK lets developers who are using native code get started with the new native APIs available in Android 4.0.
Android NDK r7 includes a number of build system improvements and bug fixes, but most importantly it gives you access to two new sets of APIs:
Low-level streaming multimedia: A new API based on provides a direct, efficient path for low-level streaming multimedia. The new path is ideal for applications that need to maintain complete control over media data before passing it to the platform for presentation. For example, media applications can now retrieve data from any source, apply proprietary encryption/decryption, and then send the data to the platform for display.
Audio decoding into PCM: Extensions to the existing native audio API based on let native apps decode compressed audio assets to PCM format.
For detailed information about how to use these new APIs, please see the documentation included with the Android NDK r7 package. To read about the build system improvements and bug fixes included in this release, check out the .
