Razorpay退款

Question

在点击删除订单，我想启动一个要求退款的剃刀支付，但一旦我点击删除订单，我的应用程序崩溃，并给我这个错误。

我遵循了在这个链接https://razorpay.com/docs/api/refunds/上发布的步骤

我用了java正常的退款。

请帮我谢谢。

代码：

if(payid!= null) {

        RazorpayClient razorpay = null;
        try {
            razorpay = new RazorpayClient("<api_key>", "<api_secret>");
        } catch (RazorpayException e) {
            e.printStackTrace();
        }

        try {

            // Partial Refund
            JSONObject refundRequest = new JSONObject();
            refundRequest.put("amount", Amount); // Amount should be in paise
            Refund refund = razorpay.Payments.refund(payid, refundRequest); // this is line 341 of Order(Order.java:341)


        } catch (RazorpayException | JSONException e) {
            // Handle Exception
            Toast.makeText(Order.this, "Error With Refund: " + e, Toast.LENGTH_SHORT).show();
        }

        runn();

    }else {

        runn();
    }

错误

当应用程序试图在主线程中执行网络操作时，通常会发生错误android.os.NetworkOnMainThreadException at android.os.StrictMode。

为了避免这种情况，我们必须在其他线程或异步类中调用网络请求。

考虑下面的代码：

 setContentView(R.layout.user_login);

 // put this below lines under setContentView in activity
    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
