My Problem :

I have a
Nexus 10 (10") (2560 x 1600 at 300ppi)
and a
Galaxy Tab 10.1 (10" approx.) (1280x800 at 149ppi)

So it's important for me to know the PPI to position and size some UI elements of my apps/games.

Maybe there is something which already use the DisplayMetrics class of the android sdk ? (for iOS too but it's easier due to less number of models ?.. ) ?

getDeviceWidth() and getDeviceHeight() will provide the size of the screen on the device. If you are using the percentage system or a virtual resolution you then need to calculate the size in the "virtual" display. For example to create a sprite that is always 10 pixels high and 20 wide:



this.mess = abs(sin(times#))

Oh, well I'm not sure if you can get the size of the screen in inches from AGK.


this.mess = abs(sin(times#))

Yes that is my problem ... for my virtual joystick i want it approximatively with a size of 1 inch whatever the PPI is (a size of a thumb heh ! :p) ...

For iOS it's easy depending on the GetDeviceName i think (due to less number of differents devices)..

But for android it's more difficult ...

It will become very important with retina like screen or not retina ... (as Shakespeare said : that is the question :p)

I don't think you can get the screen size at all from android, but it does have the horizontal and vertical dpi in there somewhere.

With the screen physical resolution and DPI, you can work out the screen size, but since you want the dpi anyway, there it is.

Can't speak for other mobile platforms or windows, but I don't see why not.

I've not seen it mentioned in AppGameKit docs, but there are a lot of new commands so you never know.

I'd considered requesting it as a feature, but didn't really have a reason to use it.

dpi and ppi are equivalent things i guess

dpi (dot per inch) and ppi (pixel per inch) ... an inch is a physical and universal unit so it can be possible to get the real screen size no ?

the goal is to size correctly a virtual joystick (for example) ... between a 10 inches at 2560pix width and a 10 inches 1280pix width your joystick will appear 2X smaller on one of two screens with identical physical size ... that's not cool
