android - passing data b/w activities

Question

How to 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);
}
