android.media.AudioRecord库调用问题

uts插件中调用 AudioRecord初始化未报错，调用startRecording方法时报错

开始录音失败 ‍[⁠java.lang.IllegalStateException⁠]‍ {cause: null, message: "startRecording() called on an uninitialized AudioRecord."}

请问应该如何解决，延迟执行也仍然报错

import 'android.media.AudioRecord'  
import 'android.media.MediaRecorder'  
import 'android.media.AudioFormat'  
import 'android.media.MediaSyncEvent'  
import { Result } from '../interface.uts'  

let recorder: AudioRecord | null = null  

export const initAudio = async function (): Promise<Result> {  
  try {  
    const bufferSizeInBytes = AudioRecord.getMinBufferSize(  
      16000,  
      AudioFormat.CHANNEL_IN_MONO,  
      AudioFormat.ENCODING_PCM_16BIT  
    )  
    recorder = new AudioRecord(  
      MediaRecorder.AudioSource.MIC,  
      16000,  
      AudioFormat.CHANNEL_IN_MONO,  
      AudioFormat.ENCODING_PCM_16BIT,  
      bufferSizeInBytes  
    )  
    console.log('初始化录音', recorder.toString())  
    recorder.startRecording()  

    return {  
      code: 0,  
      data: {},  
      message: '成功'  
    }  
  } catch (error) {  
    console.log('开始录音失败', error)  
    return {  
      code: -1,  
      data: {},  
      message: error.toString()  
    }  
  }  
}
