Java 安卓：这个警告是什么意思？

我有一个按钮，有一些音效。当我点击按钮时，什么也没发生。没有声音播放，但也没有力关闭。调试器向我发出以下警告：

“声音池-示例1未就绪” “声音池-样本2未准备好”等

Le代码：

package com.andrew.finnandjake;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Soundboard extends Activity{
private SoundManager mSoundManager;
private int next = 0;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(0,R.raw.finn_algebraic);
mSoundManager.addSound(1,R.raw.finn_allaboardthekuckletrain);
mSoundManager.addSound(2,R.raw.finn_iminmyelement);
mSoundManager.addSound(3,R.raw.finn_shmowzow);

Button SoundButton=(Button)findViewById(R.id.Button1);
SoundButton.setOnClickListener(new OnClickListener(){
  @Override
  public void onClick(View v){
    mSoundManager.playSound(next);
    next++;
    if(next>3)
      next=0;
  }
});
}
}

加载声音需要一段时间。您可以使用

声音池.OnLoadCompleteListener

查看它们何时准备就绪。（仅限安卓2.2+）
