Question

试图通过装满负荷的id子在声音池中开标,还试图通过档案记录员这样做。

我总是有同样的例外:

This file can not be opened as a file descriptor; it is probably compressed

为什么要压缩我的话?

这里是健全的集合代码:

mySoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
try { mySoundPool.load(this, R.raw.drum, 1);
   } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Log.e(TAG, "", e);
    }

MP3是一种压缩的文档格式,因此你的MP3文件已经压缩。 http://en.wikipedia.org/wiki/MP3”rel=“nofollow noreferer” 说:

MP3, is a patented digital audio encoding format using a form of lossy data compression

https://stackoverflow.com/questions/5045267/ Soundpond-Ga-with-mp3-questions> 这一问题表明,你应使用西非经货联盟或欧佩集团对安乐施的支持,并提供另一种玩弄MP3的方法。

rel=“nofollow noreferer”>SoundPool docs 这确实意味着MP3的支持,因此我不敢肯定这里的错误。我建议你尝试用其他的MP3文档进行测试,并测试将现有的MP3改为WAV/OGG格式,以测试结果。

You ll need to rename it as Android resources don t include the file extension. Make sure you check if you have another file in res aw with the same name but a different file extension, as that could cause problems.
