What is Intent?

• Intents are system messages, running around the inside of the device, notifying applications of various events, from hardware state changes (e.g.,an SD card was inserted), to incoming data (e.g., an SMS message arrived),to application events (e.g., your activity was launched from the device’s main menu).

• Not only can you respond to intents, but you can create your own, to launch other activities, or to let you know when specific situations arise (e.g., raise such-and-so intent when the user click this button).
