$cordovaContacts not working for android v4

[varepato]

I have a button for picking contacts. The code works in android 5 to 7 but fails in android 4. This is a piece of the code:

$ionicPlatform.ready(function () {
    contactService.initService();
    vm.contacts = contactService.contacts;
    vm.pickUpContact = pickUpContact;
  });

 function pickUpContact(index) {
    $cordovaContacts.pickContact().then(function (contactPicked) {
      console.log(contactPicked);
    });
  }

I tried using the navigator.contacts.pickContact() but i get:
ContactError.OPERATION_CANCELLED_ERROR (code 6)
Maybe the code isnt working becouse when pickContact is called the app gets paused. In the cordova plugin repo, they recommend to wrap the returned object in a Contact object before using it, If the plugin returns its result in the resume event. But the ionic resume event isn't returning any result.

Help please!
