On Android Pie it's OK on many devices. But strange thing, on Xiaomi Redmi6 which is on Oreo (8.0.0) I am not facing the problem. So it's difficult to understand the problem. Sometimes it crashes on Start Effect, sometimes on Stop Effect.

Here is some log too

I am using AAudio only (because I need to change the microphone if headset is connected). Also I know about this #40.

Can you say is the bug fixed or some ways to avoid it. It says that on 8.1 bug is fixed.

[philburk]

AAudio should not be used on 8.0 because of #40.
Oboe should automatically revert to OpenSL ES.
The problem is intermittent and related to a race condition with the Java garbage collector. So on some devices it is fine but not on others.

I am using AAudio only (because I need to change the microphone if headset is connected).

If you are not using the latest Oboe, give it a try.
There were lots of changes made to the sample code.

Closing for lack of activity.
