Documentation/example on how to load stored .mbtiles files in android

[ihazbackup]

Hi,

in Android's documentation, i could not find any tutorial or sample for loading multiple downloaded raster .mbtiles-files in Android (not from assets folder, but from storage). There is one for iOS in https://maplibre.org/maplibre-native/ios/latest/documentation/maplibre-native-for-ios/multipleimagesexample/

I was wondering how you would do that in Android. Does the mbtiles:// schema also work with raster .mbtiles or only vector?

if there is any basic sample code for Android, that would be greatly appreciated

Yes it should work.

Thanks for the feedback, good idea to publish a guide for this.

So looking at iOS example from the given link, it uses MLNVectorTileSource to load the .mbtiles file. In Android, it would be RasterSource and RasterLayer?

That sounds right.

You can also use a style json with an mbtiles:// URL.

Tried it in Android and it works fine. Assuming the permissions are granted

 // List of absolute paths (string, complete with extension) to .mbtiles files in your storage
val filesList = listOf(..., ..., ....)

 // Just for ID purposes
var count = 0

filesList.forEach(x -> 
   val rasterSource = RasterSource("$count-source", "mbtiles://$x", 256) // I use 256x256 tiles
   val layerSource = RasterLayer("$count-layer", "$count-source")
   style.addSource(rasterSource)
   style.addLayer(layerSource)
   count+=1;
)
