Android Question 1dip calculation

[woniol]

Hi,
I have a question: how and when is the 1dip calculated?

I have a very rare problem with the vies in my app.
The result is that the views are 'pinched'.
This is very rare and I can't repeate it.
I also use same libs that I think can have some impact on it.

What i managed to figure out from my app logs that when it happens the 1dip size has different value
than is the views are ok.

I run it on Galaxy S7 and normaly the 1dip = 4.
But when the problem occures 1dip = 1

It happens both then the views are loaded with Loadlayout or in with the code.

Any ideas?

(Better to check the value of GetDeviceLayoutValues.Scale as 1dip is rounded to an integer.)

Make sure not to use DIP units in Process_Globals. This is the only place where it might not yet be correct.

Can something change it later, so that it's not correct in Activity_Start?
I uploaded the screenshots to show how it looks.

The value is set once when the program starts.

What is the output of Log(GetDisplayLayouyValues) when this error happens?

I will log it and let know the results. So far I have this:

Log(Activity.Height&" x "&Activity.Width)
    Log("1dip "&1dip)

And there I relized that when the problem occures 1dip 1 is logged, normaly it's 4
It might take some time, I can not reproduce this error, It happens very rare.
I'll come back.

When it's ok

1440 x 2560, scale = 4.0 (640 dpi)

is logged with

Log(GetDeviceLayoutValues)
