How can I debug my retrofit API call?

Question

I\'m using retrofit to get some data from the Flickr api. The method I\'m making the call in looks like this:

public static List getImageIds(int si

You can use the following class to log API calls

import okhttp3.OkHttpClient
import okhttp3.logging.HttpLoggingInterceptor

object HTTPLogger {
    fun getLogger(): OkHttpClient {
        /*
         * OKHTTP interceptor to log all API calls
         */
        val interceptor = HttpLoggingInterceptor()
        interceptor.level = HttpLoggingInterceptor.Level.BODY
        val client = OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .build()
        return client
    }
}

You can then call this class in your retrofit instance class like this

import retrofit2.Retrofit
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory
import retrofit2.converter.gson.GsonConverterFactory

object RetrofitClientInstance {
    private var retrofit: Retrofit? = null
    val retrofitInstance: Retrofit?
        get() {
            if (retrofit == null) {
                retrofit = Retrofit.Builder()
                        .baseUrl(Constants.BASE_URL)
                        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                        .addConverterFactory(GsonConverterFactory.create())
                        .client(HTTPLogger.getLogger())
                        .build()
            }
            return retrofit
        }
}

The dependency required is

implementation 'com.squareup.okhttp3:logging-interceptor:3.9.0'
