Hi, I am still facing this issue. I am not sure how to refresh my previous activity on back button. I had written the code of calling the intent itself of onResume() method but everytime i am press back button of next activity it goes to the previous activity's on resume method and reload that activity. And then when i click back button from there it calls that activity from which i loaded it.
*Scenario is: 1) Activity 1 - > Activity 2 2) From Activity 2 called back button 3) It goes onresume method of activity 1 and reloaded it. 4) When I click back button on activity 1 it goes to the activity 2. 5) Now, clicked back button on activity 2 6) It reloaded activity 1 by going into on resume method of it. * This loop continues till infinity and it never goes back to the home screen. Any suggetions would be a great help as I need it on urgent basis !! Thanks!!
