Bug? Tiny screen layout variant problem!

[agraham]

I am playing with a teeny tiny Android 8.1 phone with an equally teeny tiny screen. It's a Unihertz Jelly Pro. The screen layout values are 240 x 432 in portrait and 432 x 240 in landscape with a reported scale of 0.75.

My BA layout has two variants 360 x 720 and 720 x 360, both scale 1. On every other device I have this works fine but on the tiny device, no matter what the device orientation, only the portrait variant is loaded

Is the variant choice made by LoadLayout being confused by the small screen dimensions?

You have two options:

1. Keep a single variant and use anchors and designer script instead.
2. Add another smaller variant.

The variant chooser algorithm treats variants that are 20% or more larger than the screen size as invalid matches. In this case both variants do not match so a "random" one is chosen.

I had a similar issue recently: only the smallest layout would load into a panel, regardless of the size of the panel (which I For..Nexted in 20-pixel steps through every combination of widths and heights, from ludicrously small to ludicrously large).

Is there any chance of seeing the code that chooses the variant, so's I can work out why the other variants would not load?

Even better would be:

- a method that returns a list of the variants As LayoutValue (or even just the number of variants), and
- a LoadLayout2(LayoutName, VariantNumber) method

You have two options:

3) Have two separate layouts each with one variant and load the correct one in Activity_Create. That works across all device screen sizes.

I was intending, part amusedly, to comment on Erel's suggestion that there were two solutions by offering a third that I have adopted. I wasn't referencing your problem or solution.
