Introduction

Networking is essential for Android apps to fetch data from servers. Whether you're building a weather app or a social media platform, understanding how to handle network requests is crucial. 🌍📡

Key Concepts

  • HTTP Methods: GET, POST, PUT, DELETE are the core methods for data interaction.
    HTTP Methods
  • Network Permissions: Always add <uses-permission android:name="android.permission.INTERNET" /> to your AndroidManifest.xml.
    Network Permissions
  • Async Tasks: Use AsyncTask or kotlinx.coroutines to avoid blocking the main thread.
    Async Tasks

Practical Examples

  1. Fetching Data: 
    // Example: Using Retrofit for API calls
public interface ApiService {
    @GET("users")
    Call<User> getUserData();
}
  2. Handling Responses:
    • Success: ✅ onResponse(Call, Response)
    • Failure: ❌ onFailure(Call)

Best Practices

  • Always check internet connectivity before making requests.
  • Use HTTPS for secure data transmission. 🔒
  • Cache responses to improve performance. 📁
