注意:下面是版本1.0,现在paytm更新了他们的sdk,所以你需要相应地改变它.

并下载Android + SDK

将下面的代码放在你的函数中或者你想要启动paytm的东西.

    private int randomInt = 0;
    private PaytmPGService Service = null;

    Random randomGenerator = new Random();
    randomInt = randomGenerator.nextInt(1000);
    //for testing environment   
    Service = PaytmPGService.getStagingService();
    //for production environment 
    /*Service = PaytmPGService.getProductionService();*/ 

    /*PaytmMerchant constructor takes two parameters
    1) Checksum generation url
    2) Checksum verification url
    Merchant should replace the below values with his values*/


PaytmMerchant Merchant = new PaytmMerchant("https://pguat.paytm.com/merchant-chksum/ChecksumGenerator","https://pguat.paytm.com/merchant-chksum/ValidateChksum");

    //below parameter map is required to construct PaytmOrder object, Merchant should replace below map values with his own values

    Map<String, String> paramMap = new HashMap<String, String>();

        //these are mandatory parameters
        paramMap.put("REQUEST_TYPE", "DEFAULT");
        paramMap.put("ORDER_ID", String.valueOf(randomInt));
        //MID provided by paytm
        paramMap.put("MID", "id provided by paytm");
        paramMap.put("CUST_ID", "CUST123");
        paramMap.put("CHANNEL_ID", "WAP");
        paramMap.put("INDUSTRY_TYPE_ID", "Retail");
        paramMap.put("WEBSITE", "paytm");
        paramMap.put("TXN_AMOUNT", "1");
        paramMap.put("THEME", "merchant");          

        PaytmOrder Order = new PaytmOrder(paramMap);


Service.initialize(Order, Merchant,null);
        Service.startPaymentTransaction(activity, false, false, new PaytmPaymentTransactionCallback() {
        @Override
        public void onTransactionSuccess(Bundle bundle) {
            app.getLogger().error("Transaction Success :" + bundle);
        }

        @Override
        public void onTransactionFailure(String s, Bundle bundle) {
            app.getLogger().error("Transaction Failure :" + s + "\n" + bundle);
        }

        @Override
        public void networkNotAvailable() {
            app.getLogger().error("network unavailable :");
        }

        @Override
        public void clientAuthenticationFailed(String s) {
            app.getLogger().error("clientAuthenticationFailed :" + s);
        }

        @Override
        public void someUIErrorOccurred(String s) {
            app.getLogger().error("someUIErrorOccurred :" + s);
        }

        @Override
        public void onErrorLoadingWebPage(int i, String s, String s2) {
            app.getLogger().error("errorLoadingWebPage :" + i + "\n" + s + "\n" + s2);
        }
    });
    }

另外一件事是你需要在AndroidManifest.xml文件中声明一个活动:

<activity
            android:name="com.paytm.pgsdk.PaytmPGActivity"
            android:theme="@style/AppTheme"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="stateHidden"/>

希望以上代码示例对您有所帮助.另外一件事是当您下载Android + SDK时,您将获得一个需要在项目中添加的jar文件pgsdk.jar文件和MainActivity.java类文件以供我们参考.请享用!!!

注意:ChecksumGenerator和ValidateChksum网址仅供测试目的使用,由paytm开发支持团队提供.您需要在自己的服务器上生成它以重定向相应的URL.
