SoundPool问题 asset的使用

float j = 1.0f; SoundPool sp = null; int sID = 0; @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.main);     Button b = (Button)findViewById(R.id.Button01);     b.setOnClickListener(new OnClickListener() {         @Override         public void onClick(View v) {             j = (float) (j +.5f);             sp.setRate(sID,j);         }     });     AssetFileDescriptor afd;     try {         sp = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);         afd = getAssets().openFd("wav/sample.wav");         int id = sp.load(afd, 1);         sID = sp.play(id, 1, 1, 1, 0, j);     } catch (IOException e) {         // TODO Auto-generated catch block         e.printStackTrace();     } }

SoundPool 大小文件在1m的样子，同时setrate的频率 在0.5- 2注意约束
