Offline Download very slow

[georgbachmann]

Currently the SDK loads every single tile on it's own. In my opinion this is is quite bad in a lot of ways.

• There are 10s of thousands of network connections having to be opened for a mid-size region
• Makes it hard to ever get background-downloading on e.g. iOS
• Download speed is super slow because of the huge number of small files that need to be transfered

There is no way around that, right? I'd love to see an plug-able offline handling. Cause then I could pre-package larger areas on the server and make them available inside the app using my own offline-code...

But as I see it, that's currently not possible? Or am I missing something?

If you pre-package the tiles into a database file (sql with the correct schema) you can merge that db on the client with OfflineManager#mergeOfflineDatabaseFile or similar (thats on Android).

You could manually download the tiles and prepare the .db on the client, or (in your case) prepare the .db file on your own server and download it as 1 file.

I seem to remember that a tool to package the tiles exists but I can't remember if it was an official tool or something community made.
