Using Implicit Intents
An Intent is an object that describes to the OS something that you want it to do. With the explicit intents that you have created thus far, you explicitly name the activity that you want the OS to start, like:
Intent intent = new Intent(getActivity(), CrimePagerActivity.class); intent.putExtra(EXTRA_CRIME_ID, crimeId); startActivity(intent);
