Important: iOS 9 and iOS 10 URL Scheme Whitelist

Apple changed the canOpenURL method on iOS 9. Apps which are checking for URL Schemes have to declare these Schemes as it is submitted to Apple. The article Quick Take on iOS 9 URL Scheme Changes expains the changes in detail.

Add URL Schemes to the Whitelist

Simply open your app's .plist (usually platforms/ios/<appname>/<appname>-Info.plist) with an editor and add the following code with your needed Schemes.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>twitter</string>
    <string>whatsapp</string>
</array>

1. Description

This plugin allows you to check if an app is installed on the user's device. It requires an URI Scheme (e.g. twitter://) on iOS or a Package Name (e.g com.twitter.android) on Android.

Supported Platforms

2. Installation

The Cordova CLI is the recommended way to install AppAvailability, see The Command-line Interface. You can find the plugin on these registries:

Automatically (Command-line Interface)

Simply run this command to add the latest version of AppAvailability from npm to your project:

$ cordova plugin add cordova-plugin-appavailability --save

Don't forget to prepare and compile your project:

$ cordova prepare
$ cordova build

You don't have to reference the JavaScript in your index.html.

Alternatively you can install AppAvailability from GitHub:

$ cordova plugin add https://github.com/ohh2ahh/AppAvailability.git --save

PhoneGap Build

AppAvailability works with PhoneGap build too. You can include this plugin from either npm or directly from this repository:

<plugin name="cordova-plugin-appavailability" source="npm" />

<plugin spec="https://github.com/ohh2ahh/AppAvailability.git" source="git" />

There is no need to reference the JavaScript in your index.html.

3. Usage

:exclamation: The code changed in version 0.3.0 and supports now success and error callbacks! But you can still use the old approach, which is described below.

iOS

appAvailability.check(
    'twitter://', // URI Scheme
    function() {  // Success callback
        console.log('Twitter is available');
    },
    function() {  // Error callback
        console.log('Twitter is not available');
    }
);

Android

appAvailability.check(
    'com.twitter.android', // Package Name
    function(info) {           // Success callback        
        // Info parameter is available only for android
        console.log('Twitter is available, and it\'s version is ', info.version);
    },
    function() {           // Error callback
        console.log('Twitter is not available');
    }
);

Full Example

var scheme;

// Don't forget to add the cordova-plugin-device plugin for `device.platform`
if(device.platform === 'iOS') {
    scheme = 'twitter://';
}
else if(device.platform === 'Android') {
    scheme = 'com.twitter.android';
}

appAvailability.check(
    scheme,       // URI Scheme or Package Name
    function() {  // Success callback
        console.log(scheme + ' is available :)');
    },
    function() {  // Error callback
        console.log(scheme + ' is not available :(');
    }
);

Old Approach (AppAvailability < 0.3.0)

The only thing you have to do is replacing appAvailability.check with appAvailability.checkBool:

appAvailability.checkBool('twitter://', function(availability) {
    // availability is either true or false
    if(availability) { console.log('Twitter is available'); }
});

4. Some URI Schemes / Package Names

How do I get the URI Scheme / Package Name?
