## Building (android)

Builds are provided in the [release tab](https://git.mrcyjanek.net/mrcyjanek/monero_c/releases), built using Gitea Runners. Building locally is possible as well, althought it is rather a heavy task which takes ~2 hours to finish (excluding enviroment setup and some downloads).

Base image for the runner is `git.mrcyjanek.net/mrcyjanek/androidndk:r17c`, which contains preinstalled NDK. `Dockerfile` can be obtained from [mrcyjanek/CIimages](https://git.mrcyjanek.net/mrcyjanek/CIimages/src/branch/master/Dockerfile.androidndk-r17c) repository.

Then to build `.github/workflows/*.yml` files are used.

Local build?

```bash
$ act --pull=false -Pandroidndk-r17c=git.mrcyjanek.net/mrcyjanek/androidndk:r17c
```

For development?

```bash
$ timeout 5 act --pull=false -Pandroidndk-r17c=git.mrcyjanek.net/mrcyjanek/androidndk:r17c # needed to clear cache.
$ act --pull=false -Pandroidndk-r17c=git.mrcyjanek.net/mrcyjanek/androidndk:r17c --reuse
$ docker ps
