Aaudio doesn't build

Hello,

Although I added the directive #include <aaudio/AAudio.h> and added aaudio in CMakeLists.txt file in target_link_libraries section, my program doesn't compile for some reason.

What can I do to find source of the problem? I think I did everything right.

Some error messages:

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

error: undefined reference to 'AAudio_createStreamBuilder'

error: undefined reference to 'AAudioStreamBuilder_setPerformanceMode'

....

Re: Aaudio doesn't build

Probably using too low a minSdkVersion for those APIs?

Re: Aaudio doesn't build

MinSDKVersion is 22. Is it too low?

Yes, that was the case, thank you.

Re: Aaudio doesn't build

In reply to this post by Dan Albert

I agree with Dan. AAudio first appeared in Android O, API 26.

Instead of using AAudio directly, we strongly recommend using Oboe instead.

Oboe uses AAudio on API 27 and later, and uses OpenSL ES on earlier versions.

(AAudio on API 26 is not stable.)

Oboe also has multiple workarounds for problems on various devices and Android versions.

And it can help you get better latency.
