Xamarin.Forms Icons in TabbedPage

Hello!
I have a problem to show my img/icon in toolbarItems. Dont know what I forgot about. There is still I only Text = "Profile". I downloaded my icon from Android Assets Studio and put them into that new folders mipmap.
` <TabbedPage.ToolbarItems>

    <ToolbarItem Text="Add"
                 IconImageSource="profile.png"
                 Clicked="ToolbarItem_Clicked_1"/>
    <ToolbarItem Text="Profile" IconImageSource="profile.png"/>
    <!-- <ToolbarItem Text="AddGame"
                 Clicked="AddGamesItems_Clicked"/>
    <ToolbarItem Text="Delete"
                 Clicked="DeleteItem_Clicked"/>-->
</TabbedPage.ToolbarItems>

<local:HistoryPage Title="History"/>
<local:CurrentPage Title="Actual"/>
<local:FuturePage Title="Future"/>
