I've found some issues on Android.

First of all, it would not compile. It was complaining about sealed classes. I had to add this to the settings.gradle of the example app:

pluginManagement {
    buildscript {
        repositories {
            mavenCentral()
            maven {
                url = uri("https://storage.googleapis.com/r8-releases/raw")
            }
        }
        dependencies {
            classpath("com.android.tools:r8:8.2.24")
        }
    }
}

We should definitely document this somewhere, probably in the changelog. I think that's going to effect (almost) every user.

Second (in the example) I have an issue with the permission dialog.
After I give permission my finger is no longer on the record button, but the app thinks it is. There is no way to stop the recording. It does actually happen more often, also when there is no permission dialog in between.

When I do manage to get a recording I cannot listen to it. The file does not exist:

Caused by: java.io.FileNotFoundException: /data/user/0/com.example.example/cache/audio_1738920852258.m4a: open failed: ENOENT (No such file or directory)

Caused by: java.io.FileNotFoundException: /data/user/0/com.example.example/cache/audio_1738920852258.m4a: open failed: ENOENT (No such file or directory)

should be fixed now
