public class MonitorSoundFragment extends Fragment {

    private static final String TAG = "MonitorSoundFragment.class";

    private BarVisualizer envirnment_bar;

    public static MonitorSoundFragment newIntance() {
        return new MonitorSoundFragment();
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_monitor_sound, null);
        findViews(view);
        return view;
    }

    private void findViews(View view) {
        envirnment_bar = view.findViewById(R.id.environment_shower);
        envirnment_bar.setDensity(70);
        envirnment_bar.setColor(R.color.colorAccent);
        //获取AudioManager
        AudioManager audioManager = (AudioManager) getActivity().getSystemService(Context.AUDIO_SERVICE);
        envirnment_bar.setPlayer(audioManager.generateAudioSessionId());
        int volume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        Log.i(TAG, "current volume" + volume);
    }
}

this is my code, I find the parameter is int audioSessionId,So I used this method of audiomanager, but it doesn't seem feasible

I believe you want the session id of a specific MediaPlayer or AudioTrack, not audioManager.generateAudioSessionId() which gives an unused Id.
If you want the visualiser to apply to the output mix you can pass in 0

I also found same issue I have added permissions:
<uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> <uses-permission android:name="android.permission.INTERNET"/>

And verified it has permission still getting this issue

I have tried to set audio player's session ID "1009" (mAudioPlayer.getAudioSessionId();) and "0" also but none is working

This is permission issue.
Make sure your app have android.permission.RECORD_AUDIO permission.
