Apply a custom style to a Google map

Customize the styling of the base map using a JSON object defined in a raw resource file.

    private fun setMapStyle(map: GoogleMap) {
        try {
            val success = map.setMapStyle(
                MapStyleOptions.loadRawResourceStyle(
                    this,
                    R.raw.map_style
                )
            )

            if (!success) {
                Log.e(mTAG, "Style parsing failed.")
            }
        } catch (e: Resources.NotFoundException) {
            Log.e(mTAG, "Can't find style. Error: ", e)
        }
    }

Shorter version:

val style = MapStyleOptions.loadRawResourceStyle(
            this, 
            R.raw.default_map_style
            )

mMap.setMapStyle(style)
mMap.mapType = GoogleMap.MAP_TYPE_NORMAL
