Issue Overview

I am attempting to utilize the Spoonacular API from RapidAPI within my Android application, and I am configuring it to work with Unirest. Following the guidelines in the Without Maven section of the Unirest documentation, I downloaded the Unirest JAR file and made the following modifications to my build.gradle file:

apply plugin: 'com.android.application'

android {
    ...
    useLibrary 'org.apache.http.legacy'
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }
}

dependencies {
    ...
    implementation 'com.rapidapi:rapidconnect-android:0.1'
    implementation files('libs/unirest-java-1.4.9.jar')
    implementation 'org.json:json:20171018'
    implementation('org.apache.httpcomponents:httpmime:4.3.6') {
        exclude module: 'httpclient'
    }
    implementation 'org.apache.httpcomponents:httpclient-android:4.3.5'
}

apply plugin: 'com.google.gms.google-services'

The Java code I am working with is as follows:

HttpResponse<JsonNode> result = null;
try {
    result = Unirest.get("https://spoonacular-recipe-food-nutrition-v1.p.mashape.com/recipes/findByIngredients?ingredients=egg,yogurt&number=5&ranking=1")
            .header("X-Mashape-Key", "your_api_key_here")
            .header("X-Mashape-Host", "spoonacular-recipe-food-nutrition-v1.p.mashape.com")
            .asJson();
} catch (UnirestException e) {
    e.printStackTrace();
}

However, I am encountering the following error:

09-19 11:53:19.674 6789-6789/com.example.hassen.androidpim E/AndroidRuntime: FATAL EXCEPTION: main

Could anyone guide me on how to resolve this issue? I appreciate any assistance.
