title: Payu payement error "Some error occurred, Try again!"
body: <p>I have integrated payu into my android app through official docs at 
  <a href="https://www.payumoney.com/dev-guide/mobilecheckout/android.html#prereq" rel="nofollow noreferrer">https://www.payumoney.com/dev-guide/mobilecheckout/android.html#prereq</a> .</p>
  
  <p>The problem i'm facing is that my code works perfectly with test credentials, and fails when i use credentials of my live account that i want to integrate in the app.</p>
  
  <pre><code>   public void makePayment(View view) {
      String phone = "8882434664";
      String productName = "product_name";
      String firstName = "piyush";
      String txnId = "0nf7" + System.currentTimeMillis();
      String email = "piyush.jain@payu.in";
      String sUrl = "https://test.payumoney.com/mobileapp/payumoney/success.php";

      PayUmoneySdkInitilizer.PaymentParam.Builder builder = new PayUmoneySdkInitilizer.PaymentParam.Builder();

              .setKey(key)
              .setMerchantId(merchantId);
  
      PayUmoneySdkInitilizer.PaymentParam paymentParam = builder.build();
  
  
      String hash = hashCal(key + "|" + txnId + "|" + getAmount() + "|" + productName + "|"
              + firstName + "|" + email + "|" + udf1 + "|" + udf2 + "|" + udf3 + "|" + udf4 + "|" + udf5 + "|" + salt);

  <p>Extra Info: Test credentials weren't working initially. I had to contact the payu support team to activate the account after which the code was working fine. My employer said he has activated the live account so i don't know what is the issue here. </p>
