Sub Header Bar on Android Not Displayed

I have a sub header bar on one of my views – essentially styled as

class="bar bar-subheader"

and it displays fine on iOS, but on Android the only way I can get it to display is to add:

style="margin-top=49px"

Anyone know the the sub header is not displayed in the proper location? Also, will my added style of adding a 49 pixel top margin work for all Androids?

I’m using v1.0.0-rc.2
