Description

*Summary:* iOS TabGroup currently supports [activeTabIconTint](https://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.TabGroup-property-activeTabIconTint) which applies a color tint to the currently selected tab's icon. We would like to add the same to Android for parity. *Note:* Theoretically, you should be able to do this now via a res/drawable "selector" XML file as shown below, but I haven't tested it. https://github.com/appcelerator/titanium_mobile/pull/10358#issuecomment-454525273

[BottomNavigationMenuView.setIconTintList(ColorStateList tint)](https://github.com/material-components/material-components-android/blob/bf8b3e9337b86dbffb4b7dfbf59ece555991feb6/lib/java/com/google/android/material/bottomnavigation/BottomNavigationMenuView.java#L244)

https://github.com/appcelerator/titanium_mobile/compare/master...drauggres:TIMOB-26734?expand=1 Only problem with this approach is that developer must define a color for the "not active" state in xml (otherwise it would be taken from the theme), e.g.:

   <style name="Theme.MyAppTheme" parent="@style/Theme.AppCompat">
   	<item name="android:actionBarStyle">@style/Theme.MyAppTheme.ActionBar</item>
   	<item name="actionBarStyle">@style/Theme.MyAppTheme.ActionBar</item>
   </style>
   
   <style name="Theme.MyAppTheme.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid">
   	<item name="colorControlNormal">@color/my_color</item>
   </style>
   
   <color name="my_color">#8a000000</color>
