[android-developers] Re: Fwd: Audio Streaming
I think you may need to remove the @hide directives in the new API's.
I can't help you with the Eclipse plug-in though, I still use VI and
make. :)

Hey Tez,
it's not only a .jar...you need to :
1) download source code
2) Compile it ("make")
3) Create SDK ("make sdk")
It's quite easy. The problem is that you cannot use this new SDK in
Eclipse, because conflicts between the SDK and the Eclipse plugin.
There is a way to generate this plugin using the source code, but this
is what i'm trying to figure out
Cheers

Hi,
I noticed in your post that you were successful in building the new
sdk. I have been trying to accomplish the same thing. Could you send
me the jar that you compiled or maybe only the cupcake branch source
code?
Cheers,
Earlence
