在Android中录制提供例外情况

当我尝试使用以下代码通过模拟器录制音频时

  AudioRecord recordInstance = new AudioRecord(
    MediaRecorder.AudioSource.MIC, this.getFrequency(), this
      .getChannelConfiguration(), this.getAudioEncoding(),
    bufferSize);

然后我在logcat中得到以下异常：

你能弄清楚这段代码中有什么问题吗？

解决方法:

你的采样率是错误的,尝试8000Hz.这是一个模拟器限制.
