We need more information in order to reproduce this error.

What app was this? An Oboe example app our your own app?

Do our Oboe example apps work on this device?

What device was this on? Does it fail on multiple devices?

Does it fail intermittently or every time?

[mbibas]

It's happened to 3M+ users with different devices in my own app (Real-Darbuka) as well.
The app crashes without any warning on runtime or after trying to reopen the app multiple times.
It's very hard to reproduce, because not happening all the time.

There is something that I can do to protect these crashes meanwhile?

[dturner]

It's difficult to diagnose this issue without source code. Typically a SIGBUS error occurs when the CPU attempts to access memory which does not exist or that it does not have access to. This can happen easily if you're doing raw pointer arithmetic, which you probably are inside onAudioReady. SIGSEGV on the other hand can happen when you dereference a null pointer.

Please consider posting a simplified version of your app which can reproduce the issue, then we can investigate further.

[mbibas]

I just disabled the Instant Run and now it not crashing all the time. (Just sometimes) any idea why?

[dturner]

Unless you can supply the information which has been requested there is no way to diagnose your issue further. Feel free to reopen if you can supply source code.

[philburk]

Is it possible that this occurs when plugging in or unplugging headphones?
Maybe the device is closed while the callback is being processed in another thread?

[philburk]

Closing for lack of response.
