Hi Ronan,
NEON intrinsics shouldn’t cause any problems with app store submissions. It’s really an instruction set, not an API, and is widely used in iOS apps.

Great post, thanks.

I was wondering if you had any experience with iOS app store review with an app that includes Neon intrinsics? Does this type of code border on “non-public API”?

Hi,
I would love to see 3d positioning, as I mainly develop audio games, meaning they have nothing but 2d and 3d sound to let users know where things are in the environment. Mainly blind people play these games, like myself.
Thanks,
-Michael.

Thanks for the comment – but in fact, you can use JNI on Android (and we do). You can use it to call native code (built using the NDK) from Java code, or to call Java code from native code.

Or put more simply:
NDK = interface for native code (C or C++)
SDK = interface for Java code
and the JNI ties the native and Java code together.

Oops. Actually my suggestion is also wrong. You just described how you use the AudioTrack class as part of the Android SDK. So once more: “In my last post I described how we use the Android SDK and the AudioTrack class…”.

However to really set thinks clear, let me quickly elaborate on the JNI (or just have a look at http://en.wikipedia.org/wiki/Java_Native_Interface): the JNI is an interface, that allows you to use C or C++ code when using Java, “plain” Java that is. It doesn’t work with Android, there you have the NDK for that kind of thing.

Anyway. I hope I manage to get everybody confused by now, although originally I had the opposite intention.

Cheers, Audiodroid.

I believe it should say “In my last post I described how we use NDK and the Java AudioTrack…”, rather than “In my last post I described how we use JNI and the Java AudioTrack…”. Funny typo, oh and thanks for all these little infos. Great!
