Things to Remember

2. To put additional information into your intents, use the Intent.putExtra(String, *) set of methods.
3. To retrieve an extra first get the intent that started your Activity using the Activity.getIntent() method.
4. Now use the Intent.getExtras() method or the Intent.get*Extra() set of methods to retrieve your extra.
5. Refer to this Android SDK Reference to inspect the list of put* and get* extras methods to have an elaborate idea.
