问题描述

当我尝试使用以下code来记录通过模拟器音频

When I am trying to record an audio through the emulator using following code

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

然后我得到以下情况例外在logcat中:

Then I am getting following exceptions in logcat:
