1. What happens to

What is the status of It is still in the
0.9 SDK, and its setVolume methods still compile (but
AudioSystem.stayAwake does not) , yet AudioSystem is not in the
current online documentation. Is it going to be deprecated or what?


2. Error when loading app to 0.9 beta SDK

I ported my app, did a clean build and when trying to deploy it to the
emulator I get the following error:

1882 KB/s (0 bytes in 2048642.001s)
        pkg: /data/local/tmp/AndroCom.apk
Failure [-11]

adb logcat output:

I get tons of other "link of class blah-blah" failed errors - merely
for every internal class of the application...

What's wrong - we're not allowed to have internal classes anymore or
