Can no longer start engine on Android #680

Can't start engine on Android. I started off experimenting with miniaudio on Android, so I know it works. I shifted into the iOS side to get that platform working, but ended up further developing in iOS for a few months and now I need to get things working with Android again. Everything I've tried so far hasn't worked, but before I start ripping things out, if anyone sees something obvious in the logs, please let me know. Otherwise, I'll go down the path of elimination. Same problem on all androids (pixel: 3a,xl, samsung: a7, s8)

The problem is currently resolved as a stated earlier, and it wasn't a miniaudio issue.
I think the problem has to do with how certain Android targetSdkVersions allow runtime permissions or not. I think my permissions were being ignored because the app was installed with a new Sdk version over a previous version of the app where the user prompt for permissions was set many months ago (on multiple devices) and Android did not re-prompt for permissions until I manually changed the SDK version and did a clean build and install. I also think this has something to do with it too: https://stackoverflow.com/questions/45163008/android-failed-to-finalize-session-26-new-target-sdk-22-doesnt-support…

What happens when you use shared mode instead of exclusive mode?

This is the Samsung S8 on shared mode. I think it might have something to do with how miniaudio is being compiled. Previously, when it worked, I was compiling miniaudio as part of a cpp file, I was mixing C with C++. Now I am using a C file with no C++. I wonder if the C++ compiler was doing something that C compiler is not...

Update: It wasn't the C vs C++ compiler, both yielded the same problem. It was the Android targetSdkVersion. I changed it the build.gradle to 22, which is an older version. I'm using Flutter and it provides the value for the targetSdkVersion as a variable in the build.gradle. I haven't touched any of the build configs, so maybe a Flutter update caused the update to the targetSdkVersion. My next step is to see which targetSdkVersion does not work.

Update 2: It looks like the Android targetSdkVersion of 33, which is the latest is causing the problem. It maybe something to do with how this SDK version is reading permissions to record or modify audio.

Update 3: Changed back 33, rebuilt and it is still working. Cleaned the build with 33 and it is still working. So it's not clear as to what the issue was.

It looks like from your last post that's its falling back to the null backend. Check that you've enabled the microphone permission for your app.

All the permissions were there. It was only after changing the targetSdkVersion, which flushed the the old build did it start working.

But are you actually getting any valid audio data? I can see from your log that both AAudio and OpenSL is failing when trying to create the capture side:

AAudio:

D/AAudio (12774): AAudioStreamBuilder_openStream() returns -898 = AAUDIO_ERROR_ILLEGAL_ARGUMENT for (0x0)

OpenSL:

E/libOpenSLES(12774): android_audioRecorder_realize(0x7313174000) error creating AudioRecord object; status -22

As a result, it's falling back to the null backend which will just give you silence.

I've tested playback and it's definitely working here. I can't easily test capture. If it's a general error with capture on Android I'll need advice from the community, but considering both AAudio and OpenSL are failing I find that to be a highly unlikely.

The problem is currently resolved as a stated earlier, and it wasn't a miniaudio issue.
I think the problem has to do with how certain Android targetSdkVersions allow runtime permissions or not. I think my permissions were being ignored because the app was installed with a new Sdk version over a previous version of the app where the user prompt for permissions was set many months ago (on multiple devices) and Android did not re-prompt for permissions until I manually changed the SDK version and did a clean build and install. I also think this has something to do with it too: https://stackoverflow.com/questions/45163008/android-failed-to-finalize-session-26-new-target-sdk-22-doesnt-support-runti
