Question

我正在使用此方法播放资源中的声音

public void PlaySound(String sound_name) {
    try {

        if (mPlayer != null) {
            if (mPlayer.isPlaying()) {
                mPlayer.stop();
            }
            mPlayer.release();
        }
        mPlayer = new MediaPlayer();

        int timerSoundId;
        String packageName = getPackageName();
        timerSoundId = getResources().getIdentifier( sound_name , "raw" , packageName );


        AssetFileDescriptor descriptor = getResources().openRawResourceFd(timerSoundId);
        mPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
        descriptor.close();

        mPlayer.prepare();
        mPlayer.setVolume(1f, 1f);
        mPlayer.start();

    } catch (Exception e) {
    }
}

当我在设备上测试应用程序时，无论何时播放声音都会打印此错误

应用程序没有崩溃，我无法检测到任何问题。我认为原因将是音频文件的格式。他们是wav。但后来我把它们改成了mp3，仍然没什么区别。音乐播放，但留下了这些日志行。

我要担心吗？或者只是忽略它？任何建议将不胜感激......
