cordova-plugin-appavailability is not detecting facebook app

Question

I am using the AppAvailability cordova plugin to check if the facebook app is installed on a device from my own app.

In order to test its working, I have the facebook app installed on my iOS device. the appAvailability.check() should therefore execute the success function however it is executing the error callback function instead. Can you help? (I am unable to post the issue on the github page as issues are closed.)

I have this in the config.xml

<plugin name="cordova-plugin-appavailability" spec="0.4.2" source="npm" />

and in my javascript i have the following:

var scheme = "fb://";
appAvailability.check(
      scheme,       // URI Scheme or Package Name 
      function() {  // Success callback 
            alert(scheme + ' is available :)');
      },
      function() {  // Error callback 
             //this is being executed even when the fb app IS installed.
            alert(scheme + ' is not available :(');
      }
);

In your androidmanifest.xml file just add the below code on above or below tag.

    <package android:name="com.whatsapp" />
    <package android:name="com.whatsapp.w4b" />
</queries>

Sample I'm showing is for ios. Make sure you edit the plist (platforms/ios/appname/appname-Info.plist) file for your app and add facebook.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>facebook</string>
</array>
