title: How can i send back data using finish?
body: <p>Like i can send data from one activity to another using this:</p>
  
  <pre><code>intent.putExtra("Name", Value);
  </code></pre>
  
  <p>how can i send data when i am using <code>finish()</code> to get back to the previous activity.</p>
  
  <p>In my app from <code>Activity_A</code> i am going to <code>Activity_B</code>. In <code>Activity_B</code> i am marking a location on map, which gives me latitude and longitude. Then i want to use this lat and lng in <code>Activity_A</code>. But i don't want to get back to <code>Activity_A</code> using an intent, because i don't want to recreate the <code>Activity_A</code> since some data already filled will be lost.</p>
