Avalonia Android - Preferred Method for Playing WAV Files?

[jjcakes]

For my scan gun app I have a few short 1 second WAV files as audio cues for the user. What do people recommend for playing these?

Thanks!

You can use MiniAudio on many platforms including Android. See: https://github.com/mackron/miniaudio
There are a few (OSS) wrappers for C# on GitHub, making it super easy to use, while maintaining cross platform compatibility

For playing short audio feedback on Android specifically, I use Android.Media.SoundPool.

I'm new to Android so if you can point me to any examples that would be greatly appreciated.

[msneijders]

some pseudocode:

// in a part for netx.0-android

using Android.Media;

SoundPool soundPool = new SoundPool.Builder().SetMaxStreams(2)!.Build()!; // do only once
int resid = 1;// resource id of your wav/aac file
int soundId = _soundPool.Load(global::Android.App.Application.Context, resid, 1); // loading is async, you must wait for it to be loaded before play, or preload before you play
//after loading, you can reuse it to play:
//you can use soundPool LoadCompleted event to check
soundPool.Play(soundId, volume, volume, 1, 0, 1f);

And aac (audio files) in your project:

project
  |_ Resources
    |_ raw
        - negative.acc //sound for negative feedback
        - positive.acc //and for positive

dotnet should generate code for accessing these resources to get that resid, in a Resources.Raw.negative/positive.

This is using the normal dotnet Java_JNI bridge to androids api, included with dotnet-android, you can read complete api description at android api docs.

Works great, thanks so much!

For others:

You can get the resid for your resource like so, let's say for positive.acc:

Resource.Raw.positive

I had to build the solution before Resource.Raw was recognized.
