A single variant will not look good on all devices. Generally speaking you should use 3 variants: phone, 7 inch tablet and 10 inch tablet.

If you want to support both orientations then you should use 6 variants to support the 2 orientations.

Clear, great. And what about scaling? Right now I have scale factor 1.5 (240 dpi) on my Nexus. Still not sure what the best approach is.

Right now my app. that works fine on Nexus, Galaxy phone and Hero looks fine without modification. But on ViewSonic 7 inch it does not maxime to the full size of the screen. Is that normal behavior if a layout variant is not added?

Cheers,

The phone category covers the nexus one. Layouts are scaled automatically.
The problem with the larger device is that it is indeed larger. It has more room for the UI.

Clear,

So in the emulator what should I create then and with which scale factor? Should I get these from the deviced and then re-create it in the emulator?

Not sure what scaling the ViewSonic 7 inch has.

I recommend you to start with the values that show in the above image. Scale = 1 => DPI = 160.

And the thing is, I already added a 480x800 scale 1.5 variant. Shouldn't that work with the viewSonic because that is a 800x480 (landscape mode).

Cheers,

I am having the same problem with the ViewSonic 7.

I test my apps usually on my Galaxy Tab 7 and my HTC Desire. Scales perfect on both machines. It does not on a friends ViewSonic which has the same resolution as the Desire (480x800).

He told me he can set certain compatibility modes for the resolution. Maybe it has to do with that. I did not have the pad in my claws yet.

Hmmm,

My Nexus One says scale 1.5 480x800 and I created a variant for that one. I know the ViewSonic is 800x480 so shouldn't that actually work without a problem.

So Erel you say I also should use 480x320 scale 1 for the Nexus One? Nexus One is not a 7 inch as far as I know so the options are kind of strange because the Nexus One is a phone and not a tablet.

Confusing stuff. If I use your guidelines should all work fine?

The most important parameter in the resolution is the scale (or dpi). The nexus one resolution is 480x800, scale=1.5. This is similar to 320x480, scale=1.0. It is not similar to 480x800, scale=1.0.

Following the three recommended layouts will give you good results.
