I need to create a layout folder for Samsung Galaxy S Duos S7562 phone which display size is 480 x 800 pixels, 4.0 inches (~233 ppi pixel density)
I found the following tutorial for helping layout creation http://developer.android.com/guide/practices/screens_support.html
Strange thing is there is not any sample for ~233 ppi pixel density
Please advise.
Nexus S is a 4.0 inches 480x800 device and it's a normal screen size device with a hdpi density. So I guess your device has the same setting, but if you would like to know exactly these two values, you can get them programmatically with a sample app as explained here:
How to detect the android screen size programmatically ( the 4 standard sizes)?
Detecting screen density programmatically, pre-Honeycomb
Anyway, since your device should have the most common size, you can start developing your application putting the layout in the "standard" layout folder: please do not provide a layout file for any possible screen size. The link you have posted is anyway a good starting point to read in order to understand how to manage layouts on Android for different devices.
Of course, if you need to, you could think about having a different layout for the landscape orientation (layout-land folder) or for large or greater devices, like Nexus 7 o Nexus 10, using folder layout-sw600dp. The smallest-width qualifier (sw) is available only on Android 3.2 and above.
This is my suggestion and if you have a more specific issue with a layout please come here and someone will help you.
