Android Removing keys


Example

private static final String MY_PREF = "MyPref";

// ...

SharedPreferences prefs = ...;

// ...

SharedPreferences.Editor editor = prefs.edit();
editor.putString(MY_PREF, "value");
editor.remove(MY_PREF);
editor.apply();

After the apply(), prefs contains "key" -> "value", in addition to whatever it contained already. Even though it looks like I added "key" and then removed it, the remove actually happens first. The changes in the Editor are all applied in one go, not in the order you added them. All removes happen before all puts.
