在使用MediaPlayer播放音訊時報出 E/MediaPlayerNative: start called in state 1,mPlayer(0x0)

@Override
public void onClick(View v){
Bundle b = new Bundle ();
switch(v.getId ()){
case R.id.start: //獲取一個Message變數，用來傳遞點選狀態的值
msg = myHandle.obtainMessage (); //把狀態的值放在Bundle物件裡面
b.putInt(“status”,1);
msg.setData(b);
msg.sendToTarget ();
break;
    case R.id.pause:
      msg = myHandle.obtainMessage ();
      b.putInt("status",2);
      msg.setData(b);
      msg.sendToTarget ();
