@TahaTesser thank you for your response. I created another project - audiotest it is working on the device I listed above.

Hi @henoktadesse
I am seeing the same issue but adding guava and multidex, solve that problem

dependencies {
    def multidex_version = "2.0.1"
    implementation "androidx.multidex:multidex:$multidex_version"
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.guava:guava:27.0.1-android'
}
apply plugin: 'com.google.gms.google-services'

However, clicking Audioplayer button does nothing for me

Please try your code project or simplify code sample

[henoktadesse]

That may have happened because I only configured the plugins on iOS since the issue occurred on iOS platform only. The Android side of the code is working perfectly.
