Integrate Paytm PGSDK_V2.0 Android : <p>I am Integrating <code>Paytm PGSDK_V2.0</code> in my android app. I have read all documentation  on <a href="https://github.com/Paytm-Payments/Paytm_Android_App_Kit" rel="noreferrer">Github</a>. I have understand everything.but the problem is in its earlier SDK where we can simply generate checksum using <code>Paytm Merchant</code> object Like:</p>

<pre><code>PaytmMerchant merchant=new PaytmMerchant("Checksum generation url","Checksum verification url");  
</code></pre>

<p>and put this in Service Like this</p>

<pre><code> Service.initialize(Order,merchant,null);
</code></pre>

<p>But in new SDK it change to </p>

<pre><code> Service.initialize(Order,null);
</code></pre>

<p>So please help me how to generate checksum in new SDK </p>
