How to convert v3 Locus themes to new v4 format

[TrulloF]

Are there any instructions how to convert version 3 themes to be compatible with the new map format? Thanks for any hints. Even after stripping all version 3 specific tags I can't get my theme to work.

Did you already find https://github.com/mapsforge/mapsforge/blob/master/docs/Rendertheme.md
?

Fight, compare, create valid xml

Yes, but I can't find, what's wrong with it. I only get a white map with standard icons...

@TrulloF Have you tried running your theme through an XML checker? A white map may indicate unmatched tags.

Yes, I use UltraEdit. Are there any incompatible tags I may have missed? I removed Locus specific v3 stuff like scale-icon-size or bg-rect-*. Anything else to look for? I'm desperate because I like my personal theme quite much and would like to continue using it.

Have you also changed the rendertheme tag near the start of the theme?
Something like

Code Select Expand

<rendertheme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://mapsforge.org/renderTheme" xsi:schemaLocation="http://mapsforge.org/renderTheme https://raw.githubusercontent.com/mapsforge/mapsforge/master/resources/renderTheme.xsd" version="5" map-background="#F8F8F8" map-background-outside="#EEEEEE">

Copied that directly from the internal v4 Locus theme. Is there a how-to or faq available anywhere? If I use the version edited for v4 in v3 maps it works as intended.

Maybe a @voldapet may help with some tips on how he did it for the app's internal themes ...

That shouldn't happen. The rendertheme preamble should mean that your v4 theme doesn't show up in the list of themes for v3 maps and vice versa.

Sorry for the misleading description. I changed the version in the header to let it show up for v3 maps, just to check if the theme is broken. It's not, at least for v3. In v4 it shows just a white screen and standard poi icons.

You didn't mention removing all mention of "dp"...

Ok, thank you for the hint. That might be it.

Removed all dp instances, but still no luck... Anything else to try?
The locus theme checker doesn't throw any error.

Is a style menu mandatory (cat and stuff)? I don't use these in my theme.

No
