any solution?

[EirikFaerdin]

Has anyone found a way around this?

[arthas1888]

the problem is this lib assets_audio_player_web, if you don't use environment web please remove, so you can fork it that was my solution

Thanks for the tip. I have a local copy as I needed to add duck functionality in order to let my audio play in the foreground if e.g. music was already playing. I have tried to remove assets_audio_player_web, but have not been successful as it generates loads of errors I don't seem to be able to solve.
Any quick suggestions on how to remove the web part?

This method helped me. Add the following content to the assets_audio_player_web library

compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = '1.8' }
