React Native Package to Detect Call States

React Native Call Detection 🎉 🎊

This package helps to detect different call states like Incoming, Disconnected, Dialing and Connected for iOS. For android, this package will give following states, Offhook, Incoming, Disconnected and Missed. In the case of Incoming for android, the package will also provide with the incoming phone number.

Installation

Add the package to your react-native project in the following way

yarn add react-native-call-detection

For Android:-

Autolinking should work without manual changes

Usage

There are different hooks that you may get depending on the platform. Since for android you could also request the package to provide you with phone number of the caller, you will have to provide the necessary request message and the corresponding error callback. The package will request for READ_PHONE_STATE permission in android.

Its really easy to setup the package. Have a look at the following code snippet

import CallDetectorManager from 'react-native-call-detection'

startListenerTapped() {
    this.callDetector = new CallDetectorManager((event, phoneNumber)=> {
    // For iOS event will be either "Connected",
    // "Disconnected","Dialing" and "Incoming"

    // For Android event will be either "Offhook",
    // "Disconnected", "Incoming" or "Missed"
    // phoneNumber should store caller/called number


    if (event === 'Disconnected') {
    // Do something call got disconnected
    }
    else if (event === 'Connected') {
    // Do something call got connected
    // This clause will only be executed for iOS
    }
    else if (event === 'Incoming') {
    // Do something call got incoming
    }
    else if (event === 'Dialing') {
    // Do something call got dialing
    // This clause will only be executed for iOS
    }
    else if (event === 'Offhook') {
    //Device call state: Off-hook.
    // At least one call exists that is dialing,
    // active, or on hold,
    // and no calls are ringing or waiting.
    // This clause will only be executed for Android
    }
    else if (event === 'Missed') {
        // Do something call got missed
        // This clause will only be executed for Android
  }
},
false, // if you want to read the phone number of the incoming call [ANDROID], otherwise false
()=>{}, // callback if your permission got denied [ANDROID] [only if you want to read incoming number] default: console.error
{
title: 'Phone State Permission',
message: 'This app needs access to your phone state in order to react and/or to adapt to incoming calls.'
} // a custom permission request message to explain to your user, why you need the permission [recommended] - this is the default one
)
}

stopListenerTapped() {
    this.callDetector && this.callDetector.dispose();
}

Dont forget to call dispose when you don't intend to use call detection, as it will avoid memory leakages.

Example project can be used to test out the package. In the example project update the HomeComponent.js with the phone number to call

  callFriendTapped() {
  // Add the telephone num to call
    Linking.openURL('tel:5555555555')
      .catch(err => {
        console.log(err)
      });
  }

How to run an example

  1. Install node and watchman
brew install node
brew install watchman

2.   yarn

Install yarn from npm.

 npm i -g yarn

3.   Xcode

Install it from the App Store.

4.   React Native Debugger

This is an electron app that bundles react devtools, redux devtools and chrome devtools configured for use with react-native.

 brew cask install react-native-debugger

5.   Once you have done all the above steps, navigate to CallDetectionExample folder and run yarn or npm install, it will fetch all the dependencies in the node_modules folder.

6.   Run the packager npm start

7.   Update the mobile number of your friend in HomeComponent.js

 callFriendTapped() {
 // Add the telephone number
	Linking.openURL('tel:5555555555')
  .catch(err => {
    console.log(err)
  });
 }

8.   To run the example on iOS from terminal type react-native run-ios (This will open the simulator, since simulator doesnt have the support for calling I will advice you to connect your iOS device and the follow the below procedure for running the app through xcode)

or you can also run the app from xcode, for that, open /CallDectionExample/ios/CallDetectionExample.xcodeproj in xcode and run on the device.

9.   To run the example on android, connect any android device to your mac then follow the below steps

  • Navigate to android folder(./CallDectionExample/android/) folder and then run adb reverse tcp:8081 tcp:8081
  • Navigate back to example directory(CallDectionExample) and then run react-native run-android

For any problems and doubt raise an issue.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
