Android的：播放AudioTrack多次生产崩溃 [英] Android:Playing AudioTrack multiple times producing crash

问题描述

我试图播放音频的缓冲声音使用AudioTrack（.WAV）。请参阅下面的code。我需要调用这个函数一个主题下，支持同时播放。这是罚款作为一个主题之下。它工作正常播放声音正常。但是，如果我执行使用打AudioTrack一个声音此起彼伏不断（即，在完成第一个播放声音之前执行的第二个上场），生产设备崩溃（强制关闭意外错误）。
有谁碰到过这样的问题，在某种程度上解决这个问题？

I am trying to play audio buffered sound (.wav) using AudioTrack. Please see the code below. I need to call this function under a Thread to support simultaneous play. It is fine being under a Thread. It is working fine playing the sound normally. But if i execute playing the sound using AudioTrack one after another continuously(i.e. executing second play before completing the first play sound), produces device crash (force close unexpectedly error). Does anyone come across such problems and resolve it in a way?

private void PlayAudioTrack(String filePath) throws IOException
{

    if (filePath==null)
        return;

    byte[] byteData = null;

    File file = null; 
    file = new File(filePath); // sdcard path
    byteData = new byte[(int) file.length()];
    FileInputStream in = null;
    try {
        in = new FileInputStream( file );
        in.read( byteData );
        in.close(); 

    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    int intSize = android.media.AudioTrack.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
            AudioFormat.ENCODING_PCM_8BIT);

    at = new AudioTrack(AudioManager.STREAM_MUSIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
                        AudioFormat.ENCODING_PCM_8BIT, intSize, AudioTrack.MODE_STREAM);

    at.play();

    at.write(byteData, 0, byteData.length);
    at.stop();              

}
