使用ActionScript 3在Android中录制声音

我使用ActionScript 3构建了一个在桌面上录制声音的应用程序,现在我将该应用程序转换为Andriod Application,但是存在SampleDataEvent.SAMPLE_DATA事件未接收任何要记录的数据的问题
这是代码：

private var _microphone:Microphone;
private var _buffer:ByteArray = new ByteArray();
private var _difference:uint;

public function record():void
{
    if ( _microphone == null )
        _microphone = Microphone.getMicrophone();

    _difference = getTimer();
    _microphone.setSilenceLevel(_silenceLevel, _timeOut);
    _microphone.gain = _gain;
    _microphone.rate = _rate;
    _buffer.length = 0;
    _microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, onSampleData);
    _microphone.addEventListener(StatusEvent.STATUS, onStatus);
} 

private function onSampleData(event:SampleDataEvent):void
{
    _recordingEvent.time = getTimer() - _difference;
    dispatchEvent( _recordingEvent );
    var buteData:Number;
    while(event.data.bytesAvailable > 0)
    {
        buteData = event.data.readFloat();
        _buffer.writeFloat(buteData);
        soundBytes.writeFloat( buteData);
}
}

任何人都可以在这里帮助
谢谢

解决方法:

我认为,也许您不了解AIR for Android设置.如果您未签入RECORD_AUDIO.你应该检查一下.

请参考下图.
