App builder

I need an Android app. I would like it designed and built. Need to build an app which can help me post a message containing text and Link or even images on different social media platform like Facebook group and pages, whatsapp group and broadcast, telegram, instagram, twitter, LinkedIn on a single click. I can even opt for the option I want this to share at. Different Users can login into the account, have their own facebook/whatsapp/twitter/insta/linkedin details and share it on their groups respectively.
