How to set a timeout for network requests using Fast Networking Library in Kotlin Android

How to set a timeout for network requests using Fast Networking Library in Kotlin Android.

In this tutorial, we will learn how to set a timeout for network requests using the Fast Networking Library in Kotlin for Android development. The Fast Networking Library provides a simple and efficient way to handle network requests in Android applications.

Step 1: Add the Fast Networking Library to your project

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

implementation 'com.amitshekhar.android:android-networking:1.0.0'

After adding the dependency, sync your project with Gradle.

Step 2: Perform a network request with a timeout

Next, we will perform a network request with a timeout using the Fast Networking Library. Follow the steps below:

1. Import the required classes in your Kotlin file:

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

2. Set the timeout value (in milliseconds) for your network request:

   val timeout = 5000 // 5 seconds

3. Perform the network request using the Fast Networking Library:

   AndroidNetworking.get("https://api.example.com/data")
       .setPriority(Priority.MEDIUM)
       .setTimeout(timeout)
       .build()
       .getAsJSONObject(object : JSONObjectRequestListener {
           override fun onResponse(response: JSONObject) {
               // Handle the response
           }
   
           override fun onError(error: ANError) {
               // Handle the error
           }
       })

In the above code snippet, we are using the get() method to perform a GET request to the specified URL. The setPriority() method sets the priority of the request, and the setTimeout() method sets the timeout value for the request. Finally, we call the build() method to create the request and the getAsJSONObject() method to send the request and retrieve the response.

Note that the getAsJSONObject() method is used here as an example. You can use other methods like getAsJSONArray() or getAsFile() depending on your specific use case.

Step 3: Handle the response and error

Once the network request is complete, you need to handle the response and error. In the onResponse() method, you can access the response data and perform any necessary operations:

override fun onResponse(response: JSONObject) {
    // Handle the response
    val data = response.getJSONArray("data")
    // Process the data
}

In the onError() method, you can handle any errors that occurred during the network request:

override fun onError(error: ANError) {
    // Handle the error
    if (error.errorCode == 0) {
        // Timeout occurred
    } else {
        // Other errors occurred
    }
}

In the above code snippets, we are assuming that the response is in JSON format. You can modify the code accordingly if you are expecting a different response format.

Step 4: Testing the timeout

To test the timeout functionality, you can set a very small timeout value (e.g., 100 milliseconds) and observe the behavior. If the network request takes longer than the specified timeout value, the onError() method will be called with an error code of 0, indicating a timeout error.

Conclusion

In this tutorial, we learned how to set a timeout for network requests using the Fast Networking Library in Kotlin for Android development. By setting a timeout, you can control the maximum time your application waits for a response from the server, avoiding potential performance issues.
