Android devices have always varied in resolution from day one. So apps generally should have been coded to cope for that and modern apps generally do. But these days you also need to consider PPI as you could have devices with same resolution but different screen size. So while a HD screen on a 10" display x number of line of data is fine, the same on a HD screen on a 5" is probably not so good.
Anyway, I really would not worry about any of this, basically the vast majority of decent android apps scale perfectly from 2.7" phones to 10" tablets.
