• Interoperable dengan Java
• Google officially support

Contoh Code:

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        
        val button = findViewById<Button>(R.id.myButton)
        button.setOnClickListener {
            Toast.makeText(this, "Hello Kotlin!", Toast.LENGTH_SHORT).show()
        }
    }
}

Java

Bahasa klasik Android

Kelebihan:

• Banyak tutorial & resources
• Mature ecosystem
• Banyak library
• Masih widely used

Kekurangan:

• Verbose (banyak boilerplate)
• Tidak se-modern Kotlin
• Google fokus ke Kotlin

Rekomendasi: Mulai dengan Kotlin. Lebih mudah, modern, dan future-proof.

Step-by-Step: Membuat Aplikasi Pertama

Step 1: Install Android Studio

1. Download Android Studio
2. Run installer
3. Pilih “Standard” installation
4. Wait download SDK & tools (±2GB)
5. Finish!

Step 2: Create New Project

1. Open Android Studio
2. Click “New Project”
3. Pilih template: Empty Activity
4. Isi project details:
   • Name: MyFirstApp
   • Package name: com.example.myfirstapp
   • Language: Kotlin
   • Minimum SDK: API 24 (Android 7.0)
5. Click “Finish”

Step 3: Kenali Struktur Project

MyFirstApp/
├── app/
│   ├── src/
│   │   ├── main/
│   │   │   ├── java/          # Kotlin/Java code
│   │   │   ├── res/           # Resources
│   │   │   │   ├── layout/    # XML layouts
│   │   │   │   ├── drawable/  # Images
│   │   │   │   ├── values/    # Strings, colors
│   │   │   └── AndroidManifest.xml
│   └── build.gradle           # Dependencies
└── gradle/                    # Build system

File Penting:

• MainActivity.kt: Logic aplikasi
• activity_main.xml: UI layout
• AndroidManifest.xml: App configuration
• build.gradle: Dependencies & SDK version

Step 4: Design UI dengan XML

Edit res/layout/activity_main.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"
    android:gravity="center">

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello, Android!"
        android:textSize="24sp"
        android:textStyle="bold"/>

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:text="Click Me"/>

</LinearLayout>

Atau gunakan Layout Editor (drag & drop visual).

Step 5: Tambah Logic di Kotlin

Edit MainActivity.kt:

package com.example.myfirstapp

import android.os.Bundle
import android.widget.Button
import android.widget.TextView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    
    private var clickCount = 0
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        
        val textView = findViewById<TextView>(R.id.textView)
        val button = findViewById<Button>(R.id.button)
        
        button.setOnClickListener {
            clickCount++
            textView.text = "Clicked $clickCount times"
            Toast.makeText(this, "Button clicked!", Toast.LENGTH_SHORT).show()
        }
    }
}

Step 6: Run Aplikasi

Opsi 1: Emulator

1. Click “Run” (▶️) di toolbar
2. Pilih “Create New Virtual Device”
3. Pilih device (misal: Pixel 6)
4. Pilih system image (API 34 - Android 14)
5. Finish & wait emulator start
6. App akan auto-install & run

Opsi 2: Real Device

1. Enable “Developer Options” di HP:
   • Settings → About Phone
   • Tap “Build Number” 7x
2. Enable “USB Debugging”
3. Connect HP ke laptop via USB
4. Allow USB debugging
5. Click “Run” → pilih device Anda

Step 7: Testing & Debugging

Logcat: Lihat log & error

Log.d("MainActivity", "Button clicked")
Log.e("MainActivity", "Error occurred")

Breakpoint: Pause execution untuk debug

1. Click di line number (red dot)
2. Run in Debug mode (🐛)
3. Step through code

Layout Inspector: Inspect UI hierarchy real-time

Konsep Penting Android Development

1. Activity

Screen/halaman dalam aplikasi.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        // Initialize activity
    }
    
    override fun onStart() {
        // Activity visible
    }
    
    override fun onResume() {
        // Activity interactive
    }
}

2. Intent

Navigasi antar Activity atau launch external app.

// Pindah ke Activity lain
val intent = Intent(this, SecondActivity::class.java)
startActivity(intent)

// Kirim data
intent.putExtra("KEY", "value")

// Open URL
val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse("https://google.com"))
startActivity(browserIntent)

3. RecyclerView

Tampilkan list data efficiently.

val recyclerView = findViewById<RecyclerView>(R.id.recyclerView)
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = MyAdapter(dataList)

4. ViewModel & LiveData

Manage UI data dengan lifecycle-aware.

class MyViewModel : ViewModel() {
    private val _data = MutableLiveData<String>()
    val data: LiveData<String> = _data
    
    fun updateData(newData: String) {
        _data.value = newData
    }
}

5. Room Database

Local database untuk simpan data.

@Entity
data class User(
    @PrimaryKey val id: Int,
    val name: String,
    val email: String
)

@Dao
interface UserDao {
    @Query("SELECT * FROM user")
    fun getAll(): List<User>
    
    @Insert
    fun insert(user: User)
}

6. Retrofit

HTTP client untuk API calls.

interface ApiService {
    @GET("users")
    suspend fun getUsers(): List<User>
}

val retrofit = Retrofit.Builder()
    .baseUrl("https://api.example.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .build()
