In today’s rapidly advancing technological landscape, incorporating voice call functionality in mobile applications has become a necessity, especially for businesses offering customer support, telehealth, or communication services. Voice calls provide a seamless connection between app users and businesses, enabling real-time interaction. One of the most reliable platforms for voice call integration is Plivo, a cloud communication platform offering APIs for voice and messaging services.
Whether you are developing for Android or iOS, integrating Plivo into your mobile app is straightforward and scalable. In this comprehensive guide, we’ll walk you through the steps of setting up Plivo and integrating voice calls into both Android and iOS apps.
Setting Up Your Plivo Account for Voice Call Integration
Before jumping into the technical aspects, the first step is to set up an account with Plivo.
Step 1: Sign Up for Plivo
Start by visiting Plivo’s official website and creating an account. After registration, you will be provided with an API key and an Auth Token. These credentials are vital for enabling your app to connect to Plivo’s voice-calling services.
Step 2: Get a Virtual Phone Number
To make and receive calls via your app, you will need a virtual phone number from Plivo. This number acts as the caller ID for outgoing calls and will also receive incoming calls made to your app.
Step 3: Configure a Voice Application
Within your Plivo dashboard, navigate to the ‘Voice’ section and create a new voice application. This application will allow you to link your mobile app to Plivo’s infrastructure. When calls are made or received, this configuration will determine how the calls are handled by the Plivo API.
Step 4: Get Your API Credentials
Take note of the API key, Auth ID, and Auth Token from the Plivo dashboard. These credentials will be used in your app’s backend to authenticate API requests when making or receiving calls.
Integrating Voice Calls into Android Apps Using Plivo
Android app developers often face the challenge of integrating voice calls, but with Plivo’s SDK, the process becomes significantly easier. Let’s explore how you can integrate Plivo voice calls into an Android app.
Step 1: Adding the Plivo SDK
To begin, add the Plivo Android SDK to your Android project. In your project’s build.gradle file, include the following dependency:
| dependencies { implementation ‘com.plivo:plivo-android-sdk:VERSION’} |
Replace VERSION with the latest version of Plivo’s SDK, which can be found on their website or repository.
Step 2: Initializing the SDK
Once the SDK is added, initialize it in your main activity or application class by using your Plivo API credentials:
| Plivo.init(this, AUTH_ID, AUTH_TOKEN); |
Here, AUTH_ID and AUTH_TOKEN are your unique API credentials that you acquired during the account setup process.
Step 3: Making Outgoing Calls
Plivo makes it simple to set up outgoing calls. Here’s how you can make an outgoing call within your Android app:
| PlivoOutgoing outgoing = Plivo.createOutgoing();outgoing.call(contactNumber); |
This code snippet allows your app users to make voice calls to a specified phone number via the Plivo API.
Step 4: Handling Incoming Calls
For receiving incoming calls, register a receiver that listens to call events. Plivo provides a straightforward method to answer incoming calls:
| @Overridepublic void onIncomingCall(PlivoIncoming incoming) { incoming.answer();} |
Step 5: Managing Call States
To ensure a smooth user experience, you need to handle different call states such as ringing, answering, and disconnecting. Plivo’s SDK includes a listener for call events:
| Plivo.setCallListener(new CallListener() { @Override public void onCallRinging() { // Handle call ringing state } @Override public void onCallAnswered() { // Handle call answered state } @Override public void onCallDisconnected() { // Handle call disconnected state }}); |
If you’re looking to integrate voice calls in Android apps smoothly and efficiently, it’s highly recommended to hire Android developers who are experienced with Plivo. Their technical expertise can ensure the proper configuration and implementation of voice call functionalities, reducing potential pitfalls.
Integrating Voice Calls into iOS Apps Using Plivo
Just like with Android, Plivo’s SDK for iOS allows developers to seamlessly integrate voice calling functionality into iOS apps. Here’s how to set up Plivo in your iOS project.
Step 1: Adding the Plivo SDK
First, include the Plivo SDK in your iOS project by using CocoaPods. Add the following line to your Podfile:
| pod ‘PlivoVoiceKit’ |
Once you’ve added this to your Podfile, run pod install to install the Plivo SDK.
Step 2: Initializing the SDK
After adding the SDK, initialize it within your AppDelegate.swift or any appropriate file in your project:
| PlivoClient.sharedInstance().setup(withAuthId: “YOUR_AUTH_ID”, andAuthToken: “YOUR_AUTH_TOKEN”) |
Here, replace YOUR_AUTH_ID and YOUR_AUTH_TOKEN with your Plivo credentials.
Step 3: Making Outgoing Calls
For making an outgoing call in your iOS app, use the following code:
| let callParams: [String: Any] = [ “to”: contactNumber, “from”: yourPhoneNumber]PlivoClient.sharedInstance().call(with: callParams) |
This initiates an outgoing call from your app to the desired contact number.
Step 4: Handling Incoming Calls
To handle incoming calls, set up a delegate within your view controller that listens to call events:
| PlivoClient.sharedInstance().setDelegate(self) |
When an incoming call is detected, you can answer it with the following method:
| func onIncomingCall(_ call: PlivoIncomingCall) { call.answer()} |
Step 5: Managing Call States
As with Android, handling call states is essential for delivering a smooth experience. Use the following method to listen for call events:
| func onCallStateChange(_ state: PlivoCallState) { switch state { case .ringing: // Handle ringing state case .answered: // Handle call answered state case .disconnected: // Handle call disconnected state }} |
For iOS apps, integrating voice call functionality with Plivo requires deep knowledge of both the iOS SDK and communication APIs. It’s advisable to hire iOS developers with experience in working with VoIP services to ensure the best results. These developers can help you implement voice call features that are optimized for performance and user experience on iOS devices.
Best Practices for Voice Call Integration
Integrating voice calls into your app is just the beginning. To ensure a smooth user experience and avoid common pitfalls, it’s essential to follow some best practices.
1. Handle Network Latency and Connectivity Issues
Voice calls heavily rely on a stable internet connection. Implement fallback options or warnings when users experience weak connectivity. Both Android and iOS offer network monitoring APIs that can be utilized to track network status during calls.
2. Optimize Permissions
Ensure that your app properly requests microphone and phone permissions. For Android, this includes the READ_PHONE_STATE and RECORD_AUDIO permissions. On iOS, include NSMicrophoneUsageDescription in your Info.plist file to inform users why your app requires access to the microphone.
3. Test for Real-World Scenarios
Testing is crucial to the success of voice call integration. Ensure your app is thoroughly tested under various conditions, such as low bandwidth, network changes, and app backgrounding. Also, check how your app behaves when incoming calls are received while the app is in the background.
4. Provide Real-Time Feedback to Users
Users should be notified about the different states of a call, such as connecting, ringing, and disconnecting. This improves the user experience and helps them understand the call’s status at any given time.
5. Scale for Growth
As your app grows in popularity, the volume of voice calls will increase. Ensure your Plivo integration is scalable by taking advantage of features such as call queuing and automatic scaling. This will help handle high traffic and maintain call quality as your user base expands.
Why Hire Android Developers and iOS Developers for Plivo Integration
Integrating voice call functionality with Plivo is a complex task that requires a solid understanding of Android or iOS development, VoIP protocols, and API integrations. If you are building a mobile app that relies heavily on voice calls, it’s essential to have expert developers on board.
When you hire Android developers, you get professionals who are well-versed in managing SDKs, handling permissions, and ensuring seamless call experiences in Android apps. Similarly, hiring iOS developers brings in expertise on optimizing call features for iOS devices, ensuring compliance with Apple’s guidelines, and providing top-notch performance.
