As onCreate() of an Activity is called only once, this is the point where most initialization should go: calling setContentView(int) to inflate the activity's UI, using findViewById to programmatically interact with widgets in the UI, calling managedQuery(android.net.Uri, String[], String, String[], String) to retrieve cursors for data being displayed, etc.

It is inefficient to set the content in onResume() or onStart() (which are called multiple times) as the setContentView() is a heavy operation.
