• i-slint-backend-android-activity

  • Dependency android-activity ^0.5 is significantly outdated

    Upgrade to the latest version to get all the fixes, and avoid causing duplicate dependencies in projects.

    Easy way to bump dependencies: cargo install cargo-edit; cargo upgrade -i; Also check out Dependabot service on GitHub.

  • Dependency ndk ^0.8.0 is significantly outdated

    Upgrade to the latest version to get all the fixes, and avoid causing duplicate dependencies in projects.

    ndk versions

  • docs.rs build failed

    docs.rs site failed to build the crate, so users will have trouble finding the documentation. Docs.rs supports multiple platforms and custom configurations, so you can make the build work even if normal crate usage has special requirements.

    Docs.rs doesn't need to run or even link any code, so system dependencies can simply be skipped. You can also set cfg() flags just for docs.rs and use them to hide problematic code.

  • Missing categories

    Categories improve browsing of lib.rs and crates.io. Add categories = ["rendering::graphics-api"] to the Cargo.toml.

    Even if there are no categories that fit precisely, pick one that is least bad. You can also propose new categories in crates.io issue tracker.

  • Missing keywords

    Help users find your crates. Add keywords = ["slint", "android", "back-end", "events", "opengl-rendering"] (up to 5) to the Cargo.toml. Best keywords are alternative terms or their spellings that aren't in the name or description. Also add a keyword that precisely categorizes this crate and groups it with other similar crates.

  • Optional dependency 'android-activity-06' exposed as an implicit feature

    Cargo automatically makes publicly-available crate features for every optional dependency, unless the dependencies are referenced using dep: syntax. Features 'android-activity-06', 'ndk-08', 'ndk-09', 'android-activity-05' may have been unintentional.

  • Imprecise dependency requirement portable-atomic = ^1

    Cargo does not always pick latest versions of dependencies! If Cargo.lock ends up having an unexpectedly old version of the dependency, you might get a dependency that lacks features/APIs or important bugfixes that you depend on. This is most likely to happen when using the minimal-versions flag, used by users of old Rust versions.

    If you want to keep using truly minimal dependency requirements, please make sure you test them in CI with -Z minimal-versions Cargo option, because it's very easy to accidentally use a feature added in a later version.
