Study Notes

An Intent is a message-passing mechanism that glues components together in Android.
There are two kinds of Intent: implicit and explicit.
Implicit Intent is like asking someone to buy sugar without specifying where, allowing the Android runtime to find the best component to handle the request.
Explicit Intent is like asking someone to buy sugar from a specific store, specifying the exact component to handle the request.

An Intent can be created using the Intent constructor and passing the action and data as arguments.
The Intent needs to be set with an action (e.g., VIEW, DIAL, ANSWER, CALL, etc.) and data (e.g., URI, phone number, picture, etc.).

An Intent has four components: Action, Data, Category, and Extras.
Action is the operation to be performed (e.g., VIEW, DIAL, ANSWER, CALL, etc.).
Data refers to the information the Action needs to work with (e.g., URI, phone number, picture, etc.).
Category determines which components are eligible to handle the Intent.
Extras are additional data that can be passed with the Intent.

Implicit Intent is used to request a functionality that doesn't exist within the app.
The Android runtime finds an application that can service the request.
Four steps are required to use an implicit Intent:
- Create the Intent object
- Set its action
- Set its data
- Launch the Intent
