Change text in editpreference by code

Question

Hi I have an edit preference and I want to change the value stored in it by code, is this possible?

I tried this but it didn't work

String input1 = hello;
prefs.getString("location", "").replace(prefs.getString("location", ""), input1);

Answer 1

prefs.edit().putString("location", MODIFIED_STRING_HERE).commit();
