Tools and libraries that simplify Android Studio setup in Android?

// Example of integrating a popular library called 'Retrofit' to simplify network operations in Android
dependencies {
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
}

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

ExampleApi exampleApi = retrofit.create(ExampleApi.class);
