The document summarizes an Android 101 workshop on getting started with Android development. The agenda includes setting up the development environment, creating a "Hello Android" project, understanding the Android manifest file which defines app components and permissions, using intents to connect components, building user interfaces with views, handling user interactions, and incorporating libraries. The workshop will also include hands-on coding examples.

- 15. Intent An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.

- 17. Intent An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
