Opt-In / Opt-Out settings :

The host application can provide an option to the users to Opt-In and Opt-Out of the Ads services. The same can be accomplished via the following methods to access or update the Status.

Update Opt-In Status

// imports and declaration

import { Platform } from '@ionic/angular';
declare var cordova : any;

// to update opt value from host app from toggle button or any UI component

cordova.plugins.amlibrary.updateOptInStatus(true);  // or false

The method accepts boolean value. When true is passed, the user is Opted-In to the Ad services and when false is passed, the user is Opted-Out of the Ad Service.

Get Opt-In status

// imports and declaration

import { Platform } from '@ionic/angular';
declare var cordova : any;

public status : boolean;

// Below code need to write inside ngOnInit()

var success = function(result) {
console.log("Home Page " + result)
    if(result == 1) {
      this.status = true; // need to use this value for UI update or as per requirement
    } else if(result == 0) {
      this.status = false; // need to use this value for UI update or as per requirement
    }
}

var failure = function(result) {
}

this.platform.ready().then(() => {
  if(cordova != null && cordova.plugins != null && cordova.plugins.amlibrary != null) {
    cordova.plugins.amlibrary.getOptInStatus("ABCD", success, failure);
  }
});

The method returns boolean value. If true is returned, the user has Opted-In to the Ad Services and when false the user is Opted-Out of the Ad Services.
