## Abin da Intents ke yi

```text
An INTENT is a message describing an operation to perform:
  → START an ACTIVITY (open another screen, in your app or another app)
  → START a SERVICE (begin background work)
  → DELIVER a BROADCAST (system/app-wide event)
  → carry DATA (extras) and specify the target/action
→ The mechanism for components to request actions and communicate.
```

## Intents mai bayani da bumanyi

```kotlin
// EXPLICIT — specify the exact component (e.g. navigate to YOUR another activity)
val intent = Intent(this, DetailActivity::class.java)
intent.putExtra("itemId", 42)        // pass data
startActivity(intent)                // open the activity

// IMPLICIT — specify an ACTION; the system finds an app that can handle it
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://example.com"))
startActivity(intent)                // opens a browser (any app that handles ACTION_VIEW)
// other examples: dial a number, share content, open the camera, send an email
```

```text
EXPLICIT → name the exact target component (used WITHIN your app, e.g. navigation)
IMPLICIT → describe an ACTION; the system picks a capable app (interact with OTHER apps:
  open a URL, share, take a photo, etc.)
```

## Watsa bayani da samar da sakamako

```text
→ EXTRAS — attach data to an intent (putExtra) → read it in the target
→ Get a RESULT back (Activity Result API) — e.g. pick an image and receive it
→ Intent FILTERS (in the manifest) declare what implicit intents your app can handle
```
