How to make a GET request using Fast Networking Library in Kotlin Android

How to make a GET request using Fast Networking Library in Kotlin Android.

Here's a step-by-step tutorial on how to make a GET request using the Fast Networking Library in Kotlin for Android.

Step 1: Set up the Fast Networking Library

First, you need to add the Fast Networking Library dependency to your project. Open your project's build.gradle file and add the following line to the dependencies block:

implementation 'com.amitshekhar.android:android-networking:1.0.2'

Sync your project to download the library.

Step 2: Make a GET request

To make a GET request using the Fast Networking Library, follow these steps:

1. Open the Kotlin file where you want to make the GET request.
2. Import the necessary classes:

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

3. Inside a function or method, write the following code to make the GET request:

AndroidNetworking.get("URL")
    .setPriority(Priority.MEDIUM)
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            // Handle the response
        }

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

Replace "URL" with the actual URL you want to make the GET request to.

4. Implement the logic to handle the response and error in the respective onResponse and onError methods.

Here's an example of handling the response:

override fun onResponse(response: JSONObject) {
    // Parse the response JSON object
    val result = response.getString("result")

    // Do something with the result
    // ...
}

And here's an example of handling the error:

override fun onError(error: ANError) {
    // Get the error message
    val errorMessage = error.message

    // Handle the error
    // ...
}

That's it! You have successfully made a GET request using the Fast Networking Library in Kotlin for Android.

Additional Features

The Fast Networking Library provides several additional features that you can use to customize your GET request. Here are a few examples:

Adding Query Parameters

You can add query parameters to your GET request by using the addQueryParameter method. For example:

AndroidNetworking.get("URL")
    .addQueryParameter("param1", "value1")
    .addQueryParameter("param2", "value2")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        // ...
    })

Setting Request Headers

You can set request headers using the addHeaders method. For example:

AndroidNetworking.get("URL")
    .addHeaders("Authorization", "Bearer token")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        // ...
    })

Setting Request Priority

You can set the priority of the request using the setPriority method. The available priorities are Priority.LOW, Priority.MEDIUM, and Priority.HIGH. For example:

AndroidNetworking.get("URL")
    .setPriority(Priority.HIGH)
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        // ...
    })

Cancelling a Request

If you want to cancel a request, you can call the cancel method on the request object. For example:

val request = AndroidNetworking.get("URL")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        // ...
    })

// Cancel the request
request.cancel()

Conclusion

In this tutorial, you learned how to make a GET request using the Fast Networking Library in Kotlin for Android. You also explored some additional features provided by the library, such as adding query parameters, setting request headers, setting request priority, and cancelling a request. Now you can easily fetch data from a server using the Fast Networking Library in your Kotlin Android app.
