data class AppData(
    val displayName: String,      // App display name
    val baseUrl: String,          // App base URL
    val isActive: Boolean,        // Active status
    var status: String = "unknown", // Health status
    var version: String = "--",   // App version
    var timestamp: String = "--", // Last check time
    var responseTime: Int? = null // Response time in ms
)

private val apiBaseUrl = "http://example.com"
private val accessToken = "KEY_ACCESS"

• GET /api/apps - Returns JSON array of application data

[
  {
    "displayName": "App Name",
    "baseUrl": "https://app.example.com",
    "isActive": true,
    "lastCheck": {
      "status": "healthy",
      "version": "1.2.3",
      "checkedAt": "2024-01-01T12:00:00.000Z",
      "responseTime": 245
    }
  }
]

The app automatically adjusts layout based on screen size:

• Manual refresh: Tap refresh button in header
• Auto-refresh: Every 2 minutes (120,000ms)
• On resume: Refresh when app returns to foreground
• Visual feedback: Refresh button rotation animation

• Android Studio
• API server running at specified URL
• Valid access token

1. Update API URL in MainActivity.kt:

   private val apiBaseUrl = "http://your-api-url:port"
   private val accessToken = "your_access_token"

2. Ensure API returns data in expected JSON format

1. Clone or import project
2. Sync Gradle dependencies
3. Build and run on device/emulator

Edit res/values/colors.xml:

<color name="status_healthy">#4CAF50</color>
<color name="status_unhealthy">#F44336</color>
<color name="status_degraded">#FF9800</color>
<color name="status_unknown">#9E9E9E</color>

• Adjust card width in calculateSpanCount() method
• Modify spacing in GridSpacingItemDecoration
• Update card appearance in app_card.xml

1. No data shown

   • Check API connectivity
   • Verify access token
   • Ensure API returns proper JSON

2. Layout issues

   • Test on different screen sizes
   • Check GridLayoutManager span count

3. Refresh not working

   • Check auto-refresh interval
   • Verify coroutine scope is active
