Question 1 — What an Intent Is

✔️ A message that describes an action to perform or an event that has occurred
❌ An event handler for system broadcasts
❌ A background-running component
❌ A message that provides an interactive screen

---

Question 2 — Benefits of Intents

✔️ An intent is the “glue” that helps integrate Android apps
❌ Defines the smallest unit of execution
✔️ Simplifies development via reusable black-box components
❌ Manages secure access to structured data (ContentProvider does this)

---

Question 3 — Intent is a Passive Data Structure

❌ Cannot be used concurrently
❌ Contains only static getters/setters
✔️ Consists of fields + accessors/mutators (data-only structure)
❌ Only contains public fields

---

Question 4 — Intent Enables Late Runtime Binding

❌ Components started by intents are slow
✔️ Components can be discovered/used at runtime
❌ Discovered at compile-time
❌ Must run in separate processes

---

Question 5 — Benefits of Runtime Discovery

✔️ Enables systematic reuse of components
❌ Enhances security by disallowing trojans
❌ Ensures compile-time knowledge of components
✔️ Enables loosely coupled, dynamically extendable components

---

Question 6 — Elements of an Intent

✔️ Data
✔️ Flags
❌ URL
❌ Service
❌ Name
❌ Stack
✔️ Action
✔️ Extras

---

Question 7 — Characteristics of Implicit Intents

✔️ The name must not be specified
❌ The data must not be specified (data is optional, not forbidden)
❌ The category must not be specified (optional)
❌ The action must not be specified (action is usually required)

---

Question 8 — Implicit vs Explicit Intents

❌ Implicit = tightly coupled
✔️ Implicit delivered only if it matches an intent filter
✔️ Implicit often used for other apps’ components
✔️ Explicit delivered without consulting filters
❌ Explicit used for other apps’ components (that’s implicit)
✔️ Explicit important when starting/binding services

---

Question 9 — Elements That Must Match for Implicit Intent Filtering

❌ Flags
❌ Extras
✔️ Data
❌ Name
✔️ Category
✔️ Action

---

Question 10 — What IntentService Does

✔️ Expresses requests as intents & passes them between threads/processes
❌ Provides user-interactive screens
✔️ Handles asynchronous requests on demand
❌ Responds to broadcast announcements
