Valhalla Mobile

This project builds valhalla as a static iOS or shared Android library.

It currently only exposes the route function for the primary purpose of generating turn by turn navigation routes using a downloaded pre-parsed valhalla tileset.

We welcome contributions to expand the functionality of this library. See our CONTRIBUTING.md for more information.

Setup

Android

Using a libs.versions.toml with a build.gradle.kts

[verisons]
valhallaMobile = "0.1.0"
[libraries]
valhalla-mobile = { group = "io.github.rallista", name = "valhalla-mobile", version.ref = "valhallaMobile" }
implementation(libs.valhalla.mobile)

Using a standard build.gradle.kts

implementation("io.github.rallista:valhalla-mobile:0.1.0")

Using a standard build.gradle

implementation 'io.github.rallista:valhalla-mobile:0.1.0'

iOS

In a swift package:

let package = Package(
    dependencies: [
        .package(url: "https://github.com/rallista/valhalla-mobile.git", from: "0.1.0"),
    ],
    targets: [
        .target(
            dependencies: [
                .product(name: "Valhalla", package: "valhalla-mobile")
            ]
        ),
    ]
)

Manually Building Valhalla C++

Set up VCPKG

git clone https://github.com/microsoft/vcpkg && git -C vcpkg checkout 2024.09.23
./vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=`pwd`/vcpkg

iOS Swift Package

On iOS, you must pre-build the xcframework using the command:

./build.sh ios clean

Android

The project's build.gradle.kts includes a build task that automatically runs the script below selectively per achitecture. It's also possible to run this manually:

./build.sh android clean

Valhalla Fork

This project uses our fork of valhalla at https://github.com/Rallista/valhalla as a submodule. If a feature is missing, please open an issue or PR on that repository to upgrade it to valhalla's latest version.
