How to install?

[ThreeDeeJay]

I'm pretty new to modding on Android so I'm really confused how to install .so mods like this.
I know this mentions installing SAUtils but I'm not sure how to install that either.
There's also the ASILoader, but I'm not sure how relevant or even useful it is to this particular mod.
So, should we modify and rebuild the APK, install a separate one to install mods, copy the .so files somewhere or something else? 🤔

You have mods folder. Guess by the name now

@RusJJ So the unmodified APK supports mods?
I found this https://libertycity.net/files/gta-san-andreas-ios-android/192495-aml-apk-s-modloader-i-cleo.html
Which kinda works (I get the HRTF and 44100hz options) but after I install that, both HRTF and Positional Audio just mix audio in stereo without any HRTF. Same happens if I update the SAUtils and OpenAL .so files.

However, if I delete the game data/mods folder, then turning on positional audio does spatialize the audio.
But I want to use this OpenAL Soft mod, particularly because I want to be able to use my own HRTF MHR file/s from here, if possible.

I was not planning to add MHR files loading but i don't know why. I will take a look at it later. Right now it loads a default simple version.

It seems loading MHR might already be possible, according to this log:

However, copying the files to the folder above might be an issue for people who haven't rooted their phone (not a problem for me, because loading the MHR files externally (like say, the sdcard/Android/data// seems to be a lot more complicated:
