How to erase all SharedPreferences?

Question

Android

The cleanup function looks like this, but nothing happens to you. The context here is obtained in the constructor via getApplicationContext()

fun clear() {
        val prefs = context.getSharedPreferences("MyAppPrefs", 0)
        var editor: SharedPreferences.Editor =  prefs.edit()
        editor.clear()
        editor.putBoolean("clear", true)
        editor.apply()
    }

Answer 1

editor.clear().commit();
