Thanks You Mr.Erel. My problem is as the screen resolution varies from product to product (7" tab and Phone), the layout and the contents thereon is being displayed differently. Do i have to create layouts corresponding to the screen resolution of the device and select the appropriate layout programmatically ? is there any better solution for this?

You should have written it in your first post...

You do not need to do anything special in your code. You should instead create a layout variant for tablets and use the designer script to fine tune your layout.

There are several threads in the forum about this topic.

GetDevicePhysicalSize

Hi,
It seems that I can not use this option: GetDevicePhysicalSize
The code is not recognised.
What library should I use?
Thanks

GetDevicePhysicalSize is a routine in the Scale module that you can find here.

You can get the screen size with ApproximateScreenSize.

B4X:

Dim lv As LayoutValues
lv = GetDeviceLayoutValues
ScreenSize = lv.ApproximateScreenSize

Best regards.

What do you mean with "will this work?" ?

There isn't a "correct" answer in this case.

Click to expand...

I'm thinking that trying to determine the device type by size work may not work for phones bigger than 6inches (such as Samsung's upcoming 'Mega' phone that is 6.3 or whatever inches). I know they are rare but its just a thought.
Thats all.

Hi there,

If someone could help....

I am using this GetDevicePhysicalSize and the return value for one tablet that I have here is strange....

I returns size as 7.89 (I suppose Inch) and it is a 10inch tablet!!

GetDeviceLayoutValues returns 1024 x 720 scale = 1 (160dpi)

Eventually the calculation is right, however this tablet is for sure a 10inch.

What is wrong?

Thank you !
