Ionic tabs hidden by nav-bar only in Android

Yes it is already configured like that:

.state('menu.home', {
    url: "/home",
    abstract:  true,
    views: {
      'menuContent': {
        templateUrl: "templates/home.html",
        controller: "HomeCtrl"
      }
    }
  })

home.html is the template with the ion-tabs directive.
