I have prepared a new beta release of the Csound for Android app here:

https://github.com/gogins/csound-extended/releases/tag/v1.3.0beta2

Further improvements as compared with beta1 involve a fairly thorough
review and improvement of the CsoundOboe class that interfaces Csound
with the Android audio layer. The result appears to be an improvement
in performance and a significant decrease in audio glitches. Please
note, it is sometimes necessary to shut down other processes or enable
Airplane Mode to achieve optimal audio performance.

Feedback would be most appreciated!

Regards,
Mike

Thanks for your feedback. I have the same problem with your test file.

Oddly enough, I was testing the app with much more complex examples,
and this problem did not happen.

I believe what's happening is the Oboe stream can't be reliably ended
from the audio callback thread, which is what my app does. I will
change the code to spawn a stop call from a different thread.

Thanks! I will post a new beta very soon.

I have posted a new beta 3 for the Csound for Android app, in which
the audio output stream is stopped from a different thread than the
audio callback.

Please let me know if this helps.

Mike
