screen - What layout is suitable for 720x1280 Android devices?

Question

I have developed a clock widget. And I only have 1 res/layout and 1 res/drawable. Everything works perfectly.

It works on mdpi like Samsung Galaxy Ace. It works on hdpi like Samsung Galaxy S2. It works on xhdpi like Samsung Galaxy Note.

However I got ugly look on 720x1280 devices such as Samsung Galaxy Nexus or Sony Xperia S. And coming soon Samsung Galaxy S3.

When I provide res/layout/xhdpi which I built specifically for 720x1280 devices and then Galaxy Note will also use this layout and it looks ugly on Galaxy Note.

How to address this issue?

It is like some crossing between 720x1280 (Galaxy Nexus, Sony Xperia S, Galaxy S3) and 800x1280 (Galaxy Note).

Answer 1

The resolution and DPI of the device don't necessarily match up (high resolution doesn't mean high DPI). DPI is a ratio of the resolution of the device and its physical dimensions.

Instead of separating your layout folders by DPI, separate them by dimensions. For instance, layout-large, layout-xlarge. You can also quantify by specific sizes, such as layout-w720-h1280, in which case that would match only device with a minimum width of 720 pixels and minimum height of 1280 pixels.
