android - Using intents for passing data

Question

How do you send data from one activity to another using intents.

(Note this is a two-part question, the sending and the receiving).

I'm creating a form, and I want to save the answers to every question in an sqlite database.

Answer 1

Sending (Activity 1):

Intent intent = new Intent(MyCurentActivity.this, SecondActivity.class);
intent.putExtra("key", "enter value here");
startActivity(intent); 

Receiving (Activity 2):

String text = getIntent().getStringExtra("key");
