How can I use `asset://` for non-APK file(s) on Android in a mapbox-gl Style?

I've been using Mapbox GL Native (specifically react-native-mapbox-gl). I'm generating my own vector tiles on a server, and I'd like to have the user download them onto their device from the mobile app. Then I want Mapbox GL to use the local tiles, specified via a TileJSON file referenced in the Mapbox GL Style file.

I've got it working on iOS (at least in the simulator). My style.json looks like the following:

{
    "version":8,
    "name":"Bright",
    "sources":{
        "mapbox":{
            "type":"vector",
            "url": "asset:///absolute/path/map/tile.json"
        }
    },
    "sprite":"asset:///absolute/path/map/sprites/mysprite",
    "glyphs":"asset:///absolute/path/map/glyphs/{fontstack}/{range}.pbf",
    "metadata":{...},
    "layers":[...]
}

with the tile.json looking like:

{
    "tiles":[
        "asset:///absolute/path/map/tiles/{z}/{x}/{y}.pbf"
    ],
    "tilejson":"2.0.0",
    // plus lots of other stuff
}

On Android this doesn't work. It appears that asset:// only works on files bundled inside the APK, not on the filesystem.

Is there something I can do on the Android platform to let Mapbox GL load my downloaded tiles from off the device?

Have you tried using the file:/// path? This usually loads from your app's file directory, eg.

"file:///absolute/path/map/tiles/{z}/{x}/{y}.pbf"
