Khi ta mở một file text, hệ thống android sẽ đưa ra một
thông báo với tên các ứng dụng có thể mở file này như
officesuite, quickofffice, note color,….Vậy các ứng dụng đó
đã được cài đặt IntentFilter để báo cho Android rằng “tôi có
thể thực hiện công việc này”
Tất cả các Activity, Service và BroadCast Receiver đều sử
dụng IntentFilter để thông báo cho hệ thống biết các dạng
Implicit Intent mà nó có thể xử lý. Nói cách khác, IntentFilter
là bộ lọc chỉ cho những Intent mà nó hiểu được phép đi qua
nó.
Intent Filter mô tả khả năng của component định nghĩa nó.
