Will the ability to set custom properties with PropertyValue come back?

[VincentJoshuaET]

layer.setProperties(PropertyValue(key, value))

We have a database that contains these properties.

Thank you for reaching out @VincentJoshuaET, the SDK between v9.0.0 and v10.0.0 has been rebuild from the ground up. Instead of using PropertyValue, we use Value.java. Which is a more wide spread system for representing values across the project than solely for layer properties.

There might be a way to provide conversion from one to another with using the HashMap setup but it would require some boiler plate to get it to work. Thanks again for reaching out and using our products!

Okay but as far as I know we now are not able to set these custom Values to the layers.

There is a division in what we internally call the high and low level style API.

The high level is what you see under the style extensions:

• https://github.com/mapbox/mapbox-maps-android/tree/main/extension-style

The low level is what is available on the StyleManager interface and uses the Value API directly:

• https://github.com/mapbox/mapbox-maps-android/blob/main/sdk/src/main/java/com/mapbox/maps/Style.kt#L189-L194
