Android Auto Radio App Need Fix for Voice commands

I have an app code on Android Studio for android auto to play audio streaming live.
Usually google team approve my app but on change to new api they reject my app for an issue that i cannot fix on my side.
So i need a developer that fix my code and test it as known on android auto.

These are the message from the google review team reason of reject:
App does not perform as expected
Your app does not perform all functions properly or as expected from a user perspective.
Media Apps
Your app does not respond (no music played or error message shown) after issuing a voice command.
Messaging Apps
Your app does not respond to “Reply” when confirming or editing custom messages.
Your app does not respond to “Reply,” "Send It,” or “Cancel”.
Nav Apps
Your app does not respond after issuing a voice command.

I need the fix for my code until google review accept my app.
Ask me for further info
Thanks
