So...what's going on?

Hello,

I have a question regarding 'intent.getStringExtra()'. We added "name" as the 1st parameter, are we referring to the "name" in 'MainActivity'. Also, why do we need to create 2 'intent' classes?

Please Help!

Hi,

We only created the actual intent object once in our MainActivity. Since we want to pass data from one activity to another, we used the "putExtra". the first parameter is a key and the second parameter is the data we want to pass. the key can be any string which we can use to access the data from the other activity.

In the other activity, we can only have gotten there via intent. and as we know, we are passing data from one activity to another. so we first call "getIntent" to get the intent object we passed (not creating a new intent) and then we call "getStringExtra" on that intent and pass in our key as a parameter to access the actual data (the name string)

you are right about "name" referring to the "name" key in main activity
