title: What is net.one97.paytm ? I know it opens paytm app but what is it? And how can I find one for paypal?
body: <p>Many answers are on "How to INTEGRATE Paypal or Paytm on android app". But what I want is how to just "OPEN" the application using Intent or something.</p>
  
  <pre><code>Intent i = getPackageManager().getLaunchIntentForPackage("net.one97.paytm");
  startActivity(i);
  </code></pre>
  
  <p>Opens the paytm app on the mobile.
  Thank You</p>
