In the Play developer console it says:
Your APK does not seem to be designed for tablets
But I have added layouts to layout
I think you may have problem with layout folders layout-sw600dp, layout-sw600dp-land, layout-sw720dp and layout-sw720dp-land
Try layout folders like layout-xlarge, layout-xlarge-land and put your dimens at values-sw600dp and values-sw720dp
And also have a look at the below link
