Quote issue 814, there is still a problem on the Android platform

[zhushenwudi]

Which API doesn't behave as documented, and how does it misbehave? https://github.com/ryanheise/just_audio/issues/814#issue-1373717611

Minimal reproduction project Provide a link here using one of two options:

1. clone https://github.com/zhushenwudi/just_audio_demo
2. click play button

To Reproduce (i.e. user steps, not code) Steps to reproduce the behavior:

1. build android project and run at similator
2. see error

Error messages

1. when I click play button on arm64 api31 simulator will be ANR

Recently ran into this same error and found that it was because I had missed the permissions that were needed in the Android Setup instructions.

Took a look at your example repo, looks like you're missing those permissions in your AndroidManifest.xml as well?

    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

[ryanheise]

The submitted minimal reproduction project indeed has no permissions declared in the manifest, so that could well be it. @zhushenwudi , does that resolve your issue?

[zhushenwudi]

ok, i will test later

[zhushenwudi]

I have tested it and currently it can be played without any unresponsive issues. Quote issue #991 , found that the current setAudioSource method must be passed into the TAG attribute, otherwise an error will be reported. Please put the tag in the compulsory parameter, or check null on just_audio_background.dart 488 line before rotation type. it will be great
