According to the dump, App crashed when fmod called FMOD_Android_SetThreadAffinity in android.
Is there anyone knows why this happens?

2

It should be mentioned that the CPU is a Snapdragon 845

Hi,

Apologies about the delayed response.

Could I grab some info:
What version of Studio and integration are you using?

Are there any other logs you could pass on? FMOD Debug logs that might give us some insight to what is happening?

Are there repro steps that can cause the crash consistently or is it random?

Thank you for your response!
1、Version:2.00.04
2、Unfortunately, there is no log for Debug Callback.
3、This crash always happens when I initialize the studio system in android( CPU Snapdragon 845 ), it seems something wrong happend when setting thread affinity.

Hi,

Unfortunately, we no longer support major versions under 2.01. I would suggest migrating your version, the process of which is explained here: FMOD Studio | Advanced Topics, and hopefully that might solve the issue. In the meantime, I will try to reproduce the issue in 2.01 and see if I can find a resolution.
