Screen Resolution

So I have an issue were when I use a 16:9 aspect ratio(Most android/Nexus devices) I always have a white line at the bottom of the screen. Does anyone know the best ratio/resolution for a android device? I am working on uploading my app soon and that is my only issue.

Android devices has varies resolutions, there no "best resolution"

so i guess you have to make the gamer bigger than the actual screen so a bigger device just sees more of the game .. right?
I have the same problem.
Can I somehow stick my controls to the screen corners so they will be nicely placed in the corners on every device? Maybie with Anchor behaviour? but i haven't been working with that yet.

@philx use scale outer or inner, Ancho behavior is for UI elements, so you can make a big tiled background for offscreen.

@philx - maybe my last post in this topic will help you: http://www.scirra.com/forum/how-do-i-get-the-layout-scale_topic79444.html

I think this method of UI placement is far better than just slapping on an anchored sprite as it will always be exactly the right distance from the edges. Just make the layer they appear on to have parallax 0.

@Joannesalfa
allright. thanks for the answer

@Tobye
yeah i read that thread before .. but I just don't get the hang of it .. I guess i just have to play around with it by myself and then check back after i made some experience with it.
