Now the decode() function is called only with the output buffer and the decode() function requests (callback to Java) input data on-demand. But this did not work unless you were very careful about the sizes of the buffers. The input buffer was passed to the decode() function and the ouput buffer was supposed to be filled in - like 1:1. Second - the original algorithm of decoding was wrong. There were three problems there: first - FAAD2/FFmpeg are quite slow (but only on older devices/emulator).

I've created a follow-up project 'AACDecoder' which uses only OpenCORE aacdec library and allows using the working library in other 3rd party Android projects. ant.properties (oh, yes in rev20 you must change the name of the property 'loglevel' to 'jni.loglevel') and run Apache Ant (beginners please consult Android SDK and NDK documentation - you need to have installed Apache Ant and GNU Make - Windows users also Cygwin).

How to compile it ? Just unzip the archive, edit local.properties, copy to. You can download the sources and compiled shared libraries from the Downloads section (aacplayer-android-r20.zip). Now I am able to play streams smoothly even on the emulator (using no more than 60% of my host CPU)! I've added OpenCORE aacdec library/decoder and rewrote both Java and C parts of the player.

if you create your own AAC decoder, then as a developer you must obtain a license from the patent holders - and you must pay for it.

although Android contains AAC decoder, you cannot use it / access it natively.

So the result is that playing raw AAC on Android devices (er even on the emulator) is possible, but there are several 'buts': I tried Android 1.5 (cupcake) and Android 2.1 (Eclair) versions - both with the same results (working, but not perfect). On the emulator it works, but it is not smooth (performance problems). It failed when trying 128kbit AAC stream served by the same server - but it also failed when using mplayer or when I saved it to a file and tried the internal HTC Desire's AAC player. I tried 32kbit AAC stream served by (the exact URL you can find in the sources). Using FAAD2 library works on my HTC Desire phone without problems.

use 3rd party native library (FAAD2) to decode AAC (OK on HTC Desire, working on emulator - but slow).split the AAC stream into small file chunks (OK, but not excellent).sync ADTS header (icecast does not do it) (error).change content-type to several possibilities like audio/mpeg (error).filter the stream using local ServerSocket and:.pass a NetSocket FileHandle to MediaPlayer (error).invoke MediaPlayer on raw AAC file (error in emulator, OK on HTC Desire).invoke MediaPlayer on raw AAC URL (error).I've spent many hours by it and I want to save other's time to public what I found. How to make Android to play raw AAC files (streams) ?

This blog (and project) was written for those developers spending hours of googling the internet to answer a simple question:
