                          String timeStamp,String packageValue,String sign,String extData)

        req.packageValue	= packageValue;
        req.sign			= sign;
        req.extData			= extData;
        // 在支付之前，如果应用没有注册到微信，应该先调用IWXMsg.registerApp将应用注册到微信
        api = WXAPIFactory.createWXAPI(this, APPID,false);
        api.registerApp(APPID);
        api.sendReq(req);
    }
    
    
     /**
     * 得到支付结果回调
     */
    @Override
    public void onResp(BaseResp resp) {
        int errCode = resp.errCode;
        switch (errCode) {
            case -2:
                Toast.makeText(this,"支付取消",Toast.LENGTH_LONG).show();
                break;
            default:
                Toast.makeText(this,"支付错误,errCode "+errCode,Toast.LENGTH_LONG).show();
                break;
        }
        UnityPlayer.UnitySendMessage("SDKManager","PayCallBack",""+errCode);

        finish();//这里重要，如果没有 finish（）；将留在微信支付后的界面.
