Important: iOS 9 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.
- Ready for the Command-line Interface of Cordova / PhoneGap 3.0 and later
- Works with PhoneGap Build (more information)
Supported Platforms
- iOS
- Android
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:
- GitHub
- npm
- Cordova Plugin Registry (deprecated in favor of npm)
- PhoneGap Plugin Registry (deprecated because updating a plugin on PhoneGap Build requires a paid plan now)
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
Don't forget to prepare and compile your project:
$ 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
PhoneGap Build
AppAvailability works with PhoneGap build too. Unfortunately PhoneGap Build requires now a paid plan to update a plugin. Therefore the version on PhoneGap Build is deprecated.
You can implement version 0.3.1
of the plugin by adding the following xml to your config.xml
:
<gap:plugin name="com.ohh2ahh.plugins.appavailability" />
Or if you want to use the exact version of AppAvailability:
<gap:plugin name="com.ohh2ahh.plugins.appavailability" version="0.3.1" />
There is no need to reference the JavaScript in your index.html
.
You can find a PhoneGap Build project which demonstrates AppAvailability in the repository ohh2ahh/AppAvailability-Demo-PhoneGap-Build.
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() { // Success callback
console.log('Twitter is available');
},
function() { // Error callback
console.log('Twitter is not available');
}
);
Full Example
var scheme;
// Don't forget to add the org.apache.cordova.device plugin!
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

) - Android:
