title: How to get data from an Activity in this case?
body: <pre><code>Activity_A:
  
  {
     //calling Activity B where i find the user current location lat and lng
     Intent intent = new Intent(Activity_A.this, Activity_B.class);
     startActivity(intent);
  }
  
  Activity_B
  {
     //after getting user lat and lng, use them in Activity_C to show the initial marker position
     Intent intent = new Intent(Activity_B.this, Activity_C.class);
     startActivity(intent);
     //i don't this Activity_B to show up on back press in Activity_C hence finish(), anyways this Activity_B has no layout
     finish();
  }
  
  Activity_C:
  
  {
     //Show a map with marker at position using lat, lng values from Activity_B, allow user to drag the marker and get the new lat, lng. and then finish this Activity to go to Activity_A
     finish();
  }
  </code></pre>
  
  <p>I want this Activity_C send back values of new lat, lng to ACtivity_A without any shared preferences or global variables, i mean by using <code>startActivityForResult</code> and <code>onACtivityResult</code></p>
