Social Sharing not show content when share with application run in background on Android

I used for my app. Here is my code

<ion-content padding>
  <button ion-button (click)="share()">Share</button>


import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { SocialSharing } from '@ionic-native/social-sharing';
  selector: 'page-home',
  templateUrl: 'home.html'
export class HomePage {

  constructor(public navCtrl: NavController,
    public socialSharing: SocialSharing, ) {

  share() {
      message: "baseLink",
      url: ''

I try share with Skype but have bug in here:

  1. Click share and chose Skype -> share ok
  2. Click home to skype open in background and comback Ionic app
  3. Click share and chose Skype again --> Not show list contact to share

How I can fix it?
