Clear data on the click of backpress of activity

Question

I am getting stuck to clear the preference. I created one method to use for all activities.

 public void clearMyPrefrences() {
        SharedPreferences.Editor editor = preference.edit();
        editor.clear();
        editor.commit();
    }

But In my FirstActivity there is some EditText on which I am opening new activity and searching some contents.On the click of EditText it will open SecondActivity. When I select some option from searchmenu and back to my FirstActivity it clears data before I typed. I am calling this method on the onStop().I want to clear this data when I go back from the FirstActivity.So how should I do this??

How to clear data of preferences If I have two activites - In FirstActivity -

there are some EditText. On the click on the EditText -

SecondActivity opens. In the SecondActivity I search some data and set the selected text in the EditText of FirstActivity.

But problem is when I search and set the Text of selected item It clears all the data of FirstActivity which I typed in my activity.

And When I call above method on the onStop() it is not working.

Please tell me if there is the solution for it.Thank you.

You need to call clearMyPreferences in onDestroy() instead of onStop () to achieve your desired result.
