Hi Gord
You need to learn how to format your code in the forum. It is easy. Enclose your code using three back ticks like this:
```java
[<Your Code>]
```
You can change java for any other language (C, python, etc.)
****EDIT
Related to your last post. I believe apwidgets is not being supported so I am not sure if it will work. I have also tested your code. You can see it at the end of this post. I just edited this post to talk about your two examples above.
Back to your question. This link provides some code: Using Android MediaPlayer to play sound. - Processing 2.x and 3.x Forum
This next code is tested using P3.37 and Android Mode v4.0.1 which is from the previous link, slightly modified and tested on Samsung Galaxy S8 running on Oreo(Android version 8.0 / API 26). Make sure your mp3 file is in the data folder.

{

context = act.getApplicationContext();
try {
fd = context.getAssets().openFd("test-sound.mp3");
snd.setDataSource(fd.getFileDescriptor(),fd.getStartOffset(), fd.getLength());
}
catch (IllegalArgumentException e) {
e.printStackTrace();

I have also tested the following code which is in the same link above. It uses ketai and the cassette library, which you need to installed via the Contribution manager. Sound files need to be place in a folder named sound which is placed inside the data folder.

rect(width/2 -100, 0.15*height -15, 100*2, 15*2);
fill(250, 220, 25);
text("Playing a random sound " + fileN + "\nThis message will disappear in "+ int(holdCtr/30), width/2, 0.05*height);
