What exactly getStringExtra() is doing? i dont fully understand yet.
Hi!, as far as i understand this method does this: getStringExtra() retrieve the data (which in our case the name of the user) that previously added with putExtra() method which take a key and the value in the MainActivity?
so in order to get the value in another activity for future use(the name of the user) i need to call a get method on the key?
String name = intent.getStringExtra("name");
is it like a Map in java?
any insights or further explantion will be appericiated
Yes, exactly. Those "extras" we're adding to the intent are stored in a Bundle that maps Key-Value pairs.
