Recreating the problem is pretty simple—just try to animate the backgroundColor of any view.
<Page xmlns="http://schemas.nativescript.org/tns.xsd" loaded="loaded">
<StackLayout id="container">
<Label text="hello world" />
</StackLayout>
</Page>exports.loaded = function(args) {
var page = args.object;
page.getViewById("label").animate({
backgroundColor: "red"
});
};Here’s the full exception I get:

@tjvantoll - does it work with hex colors or if you use the
colormodule likenew color.Color("#3489db").android;? I didn't go digging in the source but wonder if the animation api doesn't have access the the "known colors" by name. Just a guess 👍tjvantoll commentedon Mar 16, 2016
Good catch @bradmartin! Using the
Colorclass does work, and that’s actually what the docs show.So now I’m curious why passing a plain color works on iOS but not on Android. It seems like they should be consistent. Also, we should probably consider adding a nicer error message when the user does pass in bad data.
Error: java.lang.NumberFormatException: Invalid int: "null"didn’t really point me in the right direction.lock commentedon Aug 30, 2019
