Maybe this is a silly question, but I'm new to java and I just want to use the audio apis, which is not provided yet.
So I tried to see how audio was manipulated in the amazon framework. I found that com.amazon.kindle.kindlet.internal.e implemented KindleContext and it had a method a() returning AudioManager; and I gussed that's what I needed.
However, when I tried to cast the the parameter to start(KindleContext ctx) to com.amazon.kindle.kindlet.internal.e, it threw a java.lang.NoClassDefFoundError exception saying com.amazon.kindle.kindlet.internal.e is missing.
Note that it had no problem to compile.
