Dianne, Ok, well, can you tell me if using the C++ Audio Libraries is merely unsupported, or is actually not possible due to the security model of the currently deployed platform (G1) ?
I mean, can I write most of my application in the standard SDK but use one outside JNI/.so that is unsupported to do my audio bits, or will that simply not work because I can't merge it with the SDK code and sign it and upload it to market and download it to a phone and have it work?
