Aggregating 2 OpenAndroMaps

[Barbudor]

Hi

I am using maps from OpenAndroMaps.
For France, there are 2 maps (north and south) with some overlap. So I have 2 XML mapsources, 1 for each half (see exemple for North below). That is working fine

Now I would love to be able to create some maps that are across the 2 France maps.
I tried to combine them using a multilayer XML :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customMultiLayerMapSource>
    <name>OAM France</name>
    <layers>
        <mapSource>
            <name>OAM France North</name>
        </mapSource>
        <mapSource>
            <name>OAM France South</name>
        </mapSource>
    </layers>
</customMultiLayerMapSource>

But that doesn't work
Would there be a way for achieving that combination?

Thanks

My XML for the north map (south is the same but pointing to the south map file):

<?xml version="1.0" encoding="UTF-8"?>
<mapsforge>
    <!-- name of the map - as shown in map source list -->
    <name>OAM France North</name>
    <!-- optional -->
    <minZoom>0</minZoom> 
    <!-- optional -->
    <maxZoom>20</maxZoom> 
    <!-- absolute or relative file name -->
    <mapFile>locusmaps/France-North_oam.osm.map</mapFile>
    <!-- optional default OSMARENDERER Theme -->
    <!-- absolute or relative file name -->
    <xmlRenderTheme>locusmaps/Elevate/Elevate_mtb.xml</xmlRenderTheme>
    <transparent>false</transparent>
    <!-- text size scale factor -->
    <textScale>1.0</textScale>
</mapsforge>

Only set the two maps defined as

<transparent>true</transparent>

in their XML mapsource file and it works.

PS : Actually, it's enough to define the map of the second layer (South in your case) as transparent

Bonjour Laurent
Sorry for late feedback, I didn't had a notification
I tried as per your suggestion

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customMultiLayerMapSource>
    <name>OAM France</name>
    <layers>
        <mapSource>
            <name>OAM France North</name>
        </mapSource>
        <mapSource>
            <transparent>true</transparent>        
            <name>OAM France South</name>
        </mapSource>
    </layers>
</customMultiLayerMapSource>

But MoBAC is complaining:

Failed to load a custom map
Element inattendu (URI:"", local:"transparent")
Les elements attendus sont {}name>

Sorry I read too fast, you meant in the individual map XML
All good now

Many thanks 👍
