Intents in Android

Intents in Android

  • Intents are system messages that run around the inside of the device and notify applications of various events, from hardware state changes (e.g., an SD card was inserted), to incoming data (e.g., a Short Message Service [SMS] message arrived), to application events (e.g., your activity was launched from the device’s main menu). Intents are much like messages or events on other operating systems. Not only can you respond to an Intent, 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 gets within 100 meters of this-and-such location).
