Passing data between activities in Android

Question

How do you pass data between activities in an Android application?

Answer 1

in your current activity, create an intent

Intent i = new Intent(getApplicationContext(), ActivityB.class); i.putExtra(key, value); startActivity(i); 

then in the other activity, retrieve those values.

Bundle extras = getIntent().getExtras();  if(extras !=null) {     String value = extras.getString(key); }
