Offline API

[tobrun]

Add support for offline API.

How far are we with this feature, any PRs necessary?
Offline support is critical for my project and is a deciding factor on the map library to use.

Looks like side-loading is outdated - guides on the website no longer tell how to make and download tiles.db for side-loading.
Would love to get some guidance on this topic @tobrun.

Will put this link for those interested. It explains how to generate a database for side-loading: https://github.com/mapbox/mapbox-gl-native/wiki/Sideloading-offline-maps

I will explore if it's possible to side-load downloaded files with path_provider like explained here: https://medium.com/@danaya/download-assets-dynamically-in-flutter-16c3472a65e5

Thank you for the link. Also eager to hear about developments for the offline capabilities!

[AAverin]

So far I have managed to side-load offline map from the network and put it to MapBox with path_provider. You can follow articles mentioned above

The wiki seems to be deleted. Could you provide the instruction for side-loading? Thank you

[Zeldroxe]

Any news about how to make tiles.db ?

Here is what I got from MapBox support.

Offline support will not be revoked from official products. Offline sideloading however is not supported anymore, and there is no plan to support it, even though it is working.

What they are saying is that you can sideload and do offline on your own, but officially they are no longer ready to spend resources on supporting sideloading functionality.

mbgl-offline tool still should be available in this repo: https://github.com/mapbox/mapbox-gl-native

Example usage was

./mbgl-offline --north [north coordinate] --west [west coordinate] --south
[south coordinate] --east [east coordinate] --minZoom [minimum zoom] --maxZoom
[maximum zoom] --output [output file path] --style [style URL] --token [mapbox
token]

It's also kind of possible to do something similar with GUI tool
https://github.com/mapbox/mapbox-gl-native-ios/releases/

I have also seen a few apps that would allow directly in the app to select a region and it would be downloaded for offline usage. Didn't explore this part yet, probably there should be something in SDK for this

[m0nac0]

I think @maximumbuster is working on a PR for an offline API, which would allow you to select and download offline regions at runtime. (There's also discussion about this feature at #88)

[Zeldroxe]

Thanks @AAverin

I don't understand how ./mbgl-offline works, what is the initial setup ? When i write the command, my terminal say that command doesn't exist, maybe need i to build something ? I tried to do what was written in the Developing section of the mapbox-gl-native but that say that my platform is not supported. (i'm currently on windows)
