Creating an OfflineTilePyramidRegionDefinition crashes with asset:// URL

[rm3dbeckers]

We've recently tested the offline download on Android and although it looks like the mapView itself accepts styleURLs looking like "asset://style.json" (they load and the tiles are being requested correctly), but the class OfflineTilePyramidRegionDefinition only seems to accept styleUrls of the form "mapbox://styles/mapbox/streets-v9". styleURLs pointing into the assets seem to later cause an error like getHost() called on null reference (or something along that line) and then result in a termination from within the mapbox-gl.so

asset:// URLs are not supported for offline. You'll need to use a mapbox:// URL, or have the style hosted somewhere else and use a regular URL.

That said, the expected behavior is an error message, not a crash. Leaving this issue open to investigate that problem.

Hi, I am currently having the same issue on iOS. mapView accepts asset:// URLs but MGLTilePyramidOfflineRegion does not allow local file URL.

Looking at the MGLTilePyramidOfflineRegion documentation and code:

Relative file URLs cannot be used as offline style URLs.

Why is that?

Why is this? If I want to serve offline tiles, I need to run a http server on the phone...
