Ionic App Availability plugin getting Error Object (...) is not a function

Question

I am trying to implement App Availability Feature in ionic. I have an app installed in my device and trying to check if that app exists from another app. But facing an issue in the same, getting the below error

Answer 1

Possibly you are facing mismatch of ionic version of app and the plugin version you installed in your app. In Ionic V3 you no need to import from '../ngx';

Ionic V3 and V4 have Different plugin url

Ionic v3 plugins

Ionic v4 plugins.

For Ionic v3 App availability

 ionic cordova plugin add cordova-plugin-appavailability
 npm install --save @ionic-native/app-availability@4

And for Ionic V4 App availability

ionic cordova plugin add cordova-plugin-appavailability
npm install @ionic-native/app-availability

npm install cmd is different for both version

Try this steps

1. remove plugin
2. Add plugin for ionic V3 compatible from here
3. Try to build now
