在Android中录制提供例外情况

概述当我尝试使用以下代码通过模拟器录制音频时AudioRecordrecordInstance=newAudioRecord(MediaRecorder.AudioSource.MIC,this.getFrequency(),this.getChannelConfiguration(),this.getAudioEncoding(),bufferSize);然后我在logcat中得到以下异常：12

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.
