Restarting the stream when receiving OnError*

[lukaszkozakiewicz]

Hey,

The full Oboe guide in https://github.com/google/oboe/blob/c5c3cc17f78974bf005bf33a2de1a093ac55cc07/docs/FullGuide.md says:

The onError*() methods should check the state of the stream as shown in the following example. You should not close or reopen the stream from the callback, use another thread instead.

On the other hand,

oboe/samples/hello-oboe/src/main/cpp/PlayAudioEngine.cpp

Line 270 in c5c3cc1

* in this method. There is no need to create a new thread.

in hello-oboe sample says there is no need to create a new thread to restart a stream. I can see that onError*() callbacks are invoked on a different (worker?) thread from onAudioReady() which would suggest one can restart the stream without creating a dedicated thread, at least on Android 8.1. So which one is true?
