How do developers work with different screen sizes ?

Hi,

Recently I started to learn Android Development and I am stuck on how to change the layout according to the screen size ?

My thoughts are:

1. Do devs. create different screens for different sizes ?
2. Do devs. create different versions of same app. for different sizes ?
3. Android/Java takes care of the size itself and dev. has nothing to do about it ?

Please tell me, my learning curve is really stuck on this part.

Thanks.

Hi,

I am using Basic4android for my android developement.
It generates native Android applications and has a powerful designer scripts feature that
let us to easily create sophisticated layouts for multiple screen size (using scripts).

Enjoy,

I developed PhotoDream its avaliable at market.
I you see it int the left, that buttons which are my tooning small yorkie,
are four different sizes drawable-ldpi 36 height,drawable-mdpi 48 height,drawable-hdpi 72height,drawable-xhdpi 96 height,
Not necessary, but it can be an option. It is better to create different layouts for different screensizes
No, android tries to fit, but will look horrible.

You can develop different screen sizes with single project.By Creating different folder under res folder

layout-small
layout-long
layout-large
layout-xlarge

//developer.android.com/guide/practices/screens_support.html

By this you can create separate xml for different layout,inorder the application to be suitable for various devices.

xlarge screens are at least 960dp x 720dp
large screens are at least 640dp x 480dp
normal screens are at least 470dp x 320dp
small screens are at least 426dp x 320dp

Note: These minimum screen sizes were not as well defined prior to Android 3.0, so you may encounter some devices that are mis-classified between normal and large. These are also based on the physical resolution of the screen, so may vary across devices—for example a 1024x720 tablet with a system bar actually has a bit less space available to the application due to it being used by the system bar.

Download the latest S.D.K. updates from google. It will give the all the sizes available for tablets. For Device i think you can use table layout with weight properties. it will draw the ui as per the screen.
