How to perform concurrent network requests using Fast Networking Library in Kotlin Android

How to perform concurrent network requests using Fast Networking Library in Kotlin Android.

Here is a step-by-step tutorial on how to perform concurrent network requests using the Fast Networking library in Kotlin for Android.

Add the Fast Networking library to your project:
- Open your project's build.gradle file.
- Add the following line to the dependencies block:
```
implementation 'com.amitshekhar.android:android-networking:1.0.2'
```
Create a new Kotlin file for your network requests.
- Right-click on your package or directory in the Project view.
- Select "New" -> "Kotlin File/Class".
- Give the file a name, such as "NetworkRequests.kt".

Import the necessary classes and packages:

import com.androidnetworking.AndroidNetworking
import com.androidnetworking.common.Priority
import com.androidnetworking.interfaces.JSONObjectRequestListener

Perform concurrent network requests:

In the NetworkRequests class, create a function to perform the requests. For example:

fun performConcurrentRequests() {
    AndroidNetworking.get("https://api.example.com/endpoint1")
        .setPriority(Priority.HIGH)
        .build()
        .getAsJSONObject(object : JSONObjectRequestListener {
            override fun onResponse(response: JSONObject) {
                // Handle the response
            }

            override fun onError(error: ANError) {
                // Handle the error
            }
        })

    AndroidNetworking.get("https://api.example.com/endpoint2")
        .setPriority(Priority.HIGH)
        .build()
        .getAsJSONObject(object : JSONObjectRequestListener {
            override fun onResponse(response: JSONObject) {
                // Handle the response
            }

            override fun onError(error: ANError) {
                // Handle the error
            }
        })
}

In this example, two GET requests are performed concurrently using the AndroidNetworking.get() method. You can modify the endpoints and request types based on your requirements.
The getAsJSONObject() method is used to handle the response as a JSON object. You can use other methods like getAsJSONArray() or getAsString() based on the expected response type.

Call the performConcurrentRequests() function:
- In your activity or fragment, create an instance of the NetworkRequests class.
- Call the performConcurrentRequests() function to start the concurrent network requests. For example:
```
val networkRequests = NetworkRequests()
networkRequests.performConcurrentRequests()
```

Handle the response and error:

Inside the onResponse() method of each request, you can access the response data and perform the necessary actions. For example:

override fun onResponse(response: JSONObject) {
    val data = response.getString("data")
    // Perform actions with the data
}

Inside the onError() method of each request, you can handle any errors that occur during the network request. For example:

override fun onError(error: ANError) {
    val errorCode = error.errorCode
    val errorMessage = error.errorBody
    // Handle the error
}

That's it! You have now learned how to perform concurrent network requests using the Fast Networking library in Kotlin for Android. You can modify the example code based on your specific requirements and add more requests as needed.
