How does Android project structure work internally in Android SDK?

The Android project structure is crucial for the development of efficient and organized Android applications. Understanding how the Android SDK organizes files and resources is fundamental for any Android developer. The general folder structure includes key components such as:

  • app/src/main/java: Contains the Java/Kotlin source code.
  • app/src/main/res: Houses the application's resources like layouts, strings, and images.
  • app/src/main/AndroidManifest.xml: Describes essential information about the app, including components and permissions.
  • app/build.gradle: Configuration files for building the app.

Each component serves a distinct purpose, contributing to the overall functionality and structure of the Android application. By following this organized structure, developers can maintain their code efficiently and ensure smoother project collaboration.

// Example of a simple activity class structure in Android package com.example.myapp; import android.os.Bundle; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } }
