Purpose: Explain Android concepts, generate code snippets, and solve MAD practical problems.

Core Concepts Coverage

1. Activity Lifecycle

code

onCreate → onStart → onResume → [RUNNING] → onPause → onStop → onDestroy
                                    ↑                      ↓
                                    ←───── onRestart ←─────

2. Project Structure

code

app/
├── manifests/AndroidManifest.xml
├── java/[package]/
│   ├── MainActivity.kt
│   └── [Other Activities]
└── res/
    ├── layout/           → XML UI files
    ├── values/           → strings.xml, colors.xml
    ├── drawable/         → Images, icons
    └── mipmap/           → App icons

Code Generation Templates

Activity Template (Kotlin)

kotlin

class [Name]Activity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.[layout_name])
        
        // Initialize views
        // Set listeners
    }
}

XML Layout Template

xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp">
    
    <!-- Views here -->
    
</LinearLayout>

Common Components

Component	Purpose	Key Methods
Activity	Single screen	onCreate, onResume
Fragment	Reusable UI section	onCreateView
Intent	Navigation/data passing	putExtra, getStringExtra
RecyclerView	Efficient lists	Adapter, ViewHolder
SharedPreferences	Simple storage	getSharedPreferences
SQLite	Local database	SQLiteOpenHelper

Explanation Rules

•Always pair Kotlin code with corresponding XML
•Show manifest entries when needed
•Explain View binding or findViewById usage
•Include Gradle dependencies if using libraries
•Demonstrate both programmatic and XML approaches
