title: ANDROID: Update data in another activity in Master Detail Flow Layout
body: <p>I've searched for a solution for my question all over the internet but I haven't been able to find one and I hope you can help me out</p>
  
  <p>I am trying to create a master detail flow application in android with 2 activities and the second activity contains a fragment. Can anyone please tell me how I can simultaneously update the value in the MainActivity() when I make a change in the fragment's EditText field? I have tried using an Intent but when the 2 activities are side by side that doesnt seem to work well.</p>
