To setup build environment manually, you can read the `Dockerfile`
and mimic what it does.
To setup build environment manually:
- _Either_, in Android Studio, go to "Tools / SDK Manager / SDK Tools", enable "Show Package Details",
select "CMake" and the desired NDK, hit "Apply".
- _Or_ read `Dockerfile` and mimic what it does.
First, you need to setup Android SDK and Android NDK. Configure
`ANDROID_NDK_ROOT` environment variable to point to the Android NDK
Currently ndk20b is the minimum required version.
Newer versions will likely work, however, changes on the ndk-version should be
done with care. Too new versions do not support abi16 and cannot be used to target Android 4.3 or lower.
Then, in both cases, install Rust using [rustup](https://rustup.rs/)
and Rust toolchains for cross-compilation by executing `scripts/install-toolchains.sh`.
Then, configure `ANDROID_NDK_ROOT` environment variable to point to the Android NDK
installation directory e.g. by adding this to your `.bashrc`:

Currently ndk20b is the minimum required version.
Newer versions will likely work, however, are not tested and not used
in official releases, in general, changes on the ndk-version should be
done with care.
Then, install Rust using [rustup](https://rustup.rs/). Install Rust
toolchains for cross-compilation by executing `scripts/install-toolchains.sh`.
After that, call `scripts/ndk-make.sh` in the root directory to build core-rust.
Afterwards run the project in Android Studio. The project requires API 25.
