For Android:
Step 1. Add RealtyFeedSDK to your project
There are two ways to add the RealtyFeedSDK into your project:

A) Add RealtyFeedSDK from the gradle

dependencies {
	implementation 'com.github.realtyna:RealtyFeedSDK-Android:0.0.2'
}

B) Download the RealtyFeedSDK latest release from Github and add it as local library
Step 2. Add the RealtyFeedSDK Initialization Code
Add the RealtyFeedSDK initialization code to App.kt.

class App : MultiDexApplication() {
	override fun onCreate() {
		super.onCreate()
		RealtyFeedSDK.initial("YOUR-API-KEY", "YOUR-RAPID-API-KEY")
	}
}

Make sure to import the RealtyFeedSDK header:

import com.realtyna.realtyfeedsdk.RealtyFeedSDK
import com.realtyna.realtyfeedsdk.API

RealtyFeedSDK.initial("YOUR-API-KEY", "YOUR-RAPID-API-KEY")

YOUR-API-KEY with your RealtyFeedSDK API Key.
YOUR-RAPID-API-KEY with your Rapid API Key.

Now you can call RealtyFeedSDK APIs anywhere of your project,
Get Listings list

API.instance.getListings { result, error ->
			Log.d("Done", result)
}

Get Property detail

API.instance.getProperty("P_5dba1fb94aa4055b9f29691f") { result, error ->
