Android Development Setup

Learn how to build Android applications in Java that connect to cloud APIs and services.

Adding Dependencies

// build.gradle (Module: app)
dependencies {
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
}

API Interface

import retrofit2.Call;
import retrofit2.http.*;

public interface ApiService {
    @GET("users")
    Call<List<User>> getUsers();
    
    @POST("users")
    Call<User> createUser(@Body User user);
}

Best Practices

• Use Retrofit for API calls
