• To start an activity: You can start a new instance of an Activity by passing an Intent to startActivity() method.
• To start a service: You can start a service to perform a one-time operation (such as download a file) by passing an Intent to startService().
• To deliver a broadcast: You can deliver a broadcast to other apps by passing an Intent to sendBroadcast(), sendOrderedBroadcast(), or sendStickyBroadcast().
