我正在我的Android应用程序中集成Paytm SDK . 我必须POST ORDER ID和callbackurl以及其他paytm凭据 . 所有值都正确传递 . 但是显示OOPS错误 .

代码公共类Paytmgateway扩展Activity {

Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.merchantapp);
    context = this;
    //  initOrderId();
    getWindow().setSoftInputMode(
            WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

}

// This is to refresh the order id: Only for the Sample App’s purpose.
@Override
protected void onStart() {
    super.onStart();
    // initOrderId();
    getWindow().setSoftInputMode(
            WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

我的Android Studio Monitor输出

System.out.println(paramMap);

是

这意味着两个参数值成功发布，我也可以获取它们 . 但是显示以下错误

我只是使用第二个代码来测试trasaction . 但我必须使用第一个发布的代码，因为我必须将ORDERID和CALLBACKURL从Android应用程序发布到服务器 . 任何帮助都会很明显 .

android paytm

    **Here is the solution for all :**

Be sure to send equal number of parameters to your server (For checksum generator) And then to paytm server for payment.

**For example:**
If you are sending 6 params for checksum generator, then send these 6 same parameters including Checksum to Paytm...
It will resolve your problem.

**CODE EXAMPLE :**

**Generate checksum.php**

$paramList = array();
$paramList["MID"] = 'Provided by Paytm'; //Provided by Paytm
$paramList["ORDER_ID"] = 'hIquwhzvzTG7gvT'; //unique OrderId for every request
$paramList["CUST_ID"] = 'CUST0001453'; // unique customer identifier
$paramList["INDUSTRY_TYPE_ID"] = 'Retail'; //Provided by Paytm
$paramList["CHANNEL_ID"] = 'WAP'; //Provided by Paytm
$paramList["TXN_AMOUNT"] = '10.00'; // transaction amount
$paramList["WEBSITE"] = 'APP_STAGING';//Provided by Paytm
$paramList["CALLBACK_URL"] = 'https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp';

**Android Activity.java**

paramMap.put("MID" , "#########");
paramMap.put( "ORDER_ID" , "hIquwhzvzTG7gvT");
paramMap.put( "CUST_ID" , "CUST0001453");
paramMap.put( "CHANNEL_ID" , "WAP");
paramMap.put( "TXN_AMOUNT" , "10.00");
paramMap.put( "WEBSITE" , "APP_STAGING");
paramMap.put( "CALLBACK_URL" , "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp");
paramMap.put( "CHECKSUMHASH" , "dR5OtEkuNkgamHTZDCHmF+CF3j9RdG1520mlHEb85oSZP1CaxVUsRY2sYric90HLm/vElaPZKoQ7b5/SyFpi3oBWXf2BQNy+r6iiBwg4AH4=");
paramMap.put("INDUSTRY_TYPE_ID" , "Retail");

**NOTE : Please keep in mind to send paytm server exact parameters plus one checksum.....**
