Theme.AppCompat do we need it?

[ember11498]

I am not even sure what Theme.AppCompat is but when my mapbox maps loads i get this messages (the map is displayed anyways):

W/om.example.tem(14226): Accessing hidden field Landroid/graphics/Typeface;->sSystemFontMap:Ljava/util/Map; (greylist, reflection, allowed)
I/Mbgl-FontUtils(14226): Couldn't map font family for local ideograph, using sans-serif instead
E/ThemeUtils(14226): View class com.mapbox.maps.plugin.compass.CompassViewImpl is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant).
E/ThemeUtils(14226): View class com.mapbox.maps.plugin.logo.LogoViewImpl is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant).
E/ThemeUtils(14226): View class com.mapbox.maps.plugin.attribution.AttributionViewImpl is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant).

Do I need to fix something?
