Maplibre-Core on android

[Murmele]

This is an initial work to get maplibre-core working on android using maplibre-native-rs.

The idea is to have custom interfaces so the Rust Functionality for Http and so on can be used instead of using the android java code. This code is far from finish, just a prototype yet but I wanna hear your opinion about.

Have you seen https://maplibre.org/maplibre-native/docs/book/rust.html?

You could probably make a Rust implementation of HTTPFileSource on this side.

[louwers]

Maybe you can look into HarfRust. ;-)

[Murmele]

But then we have to write the ffi to C++ again :). If maplibre-native is open to implement parts in Rust I am open for it :)

[louwers]

Just noticed this, but a default should be set with a description in CMakeLists.txt.

[Murmele]

You are right I forgott to do it in my previous PR. Thanks I will add

[louwers]

What's this?

[Murmele]

I need to set the jvm from externally to be able to use maplibre-native with the ndk

[Murmele]

Have you seen https://maplibre.org/maplibre-native/docs/book/rust.html?

You could probably make a Rust implementation of HTTPFileSource on this side.

The problem then is still that the http rust library is then statically linked once on the maplibre-native side and once on the rust application side?
