什么是“状态-12"?在Android AudioTrack中意味着什么? [英] What does "status -12" mean in Android AudioTrack?

问题描述

使用Android声音池/audioTrack时，出现以下错误:

When using Android soundpool/audioTrack, I keep getting the following error:

AudioFlinger could not create track, status: -12
Error creating AudioTrack

任何人都可以解释-12是什么吗?它是源代码中某些枚举的值吗?

Can anyone explain what -12 is? Is it the value of some enum from the source code?

我已经看到了其他有关错误-12的问题，但没有一个结论可以肯定地表明该常数的含义.有人知道AudioFlinger的可能状态列表吗?我也看到过错误-22，但是我也不知道这是什么意思.

I've seen other questions that deal with error -12 but nowhere conclusively do I see what that constant actually stands for. Does someone know the list of the possible statuses for AudioFlinger? I've also seen error -22 around, but I don't know what that means either.

由源代码或文档备份的答案是最好的，但是我将尽一切可能获得的信息.

Answers backed up by source code or documentation would be best, but I'll take any information I can get at this point.

推荐答案

-12 is ENOMEM Not enough space

-22 is EINVAL Invalid argument. 

这些是标准的POSIX错误代码

These are standard POSIX error codes
