| ## Ivy Big Number Calculator (Android) |
| |
| [Ivy (robpike.io/ivy)](https://robpike.io/ivy) is an interpreter for an APL-like language written in Go. |
| This repository hosts a minimal Android project used for its [Android version](https://play.google.com/store/apps/details?id=org.golang.ivy&hl=en_US&gl=US). |
| |
| ### How to build |
| |
| Requirements |
| - Go 1.17 or newer |
| - Android SDK |
| - Android NDK |
| - `golang.org/x/mobile/cmd/gomobile` |
| |
| The `gomobile` command respects the `ANDROID_HOME` and `ANDROID_NDK_HOME` environment variables. If `gomobile` can't find your SDK and NDK, you can set these environment variables to specify their locations: |
| ``` |
| export ANDROID_HOME=/path/to/sdk-directory |
| export ANDROID_NDK_HOME=/path/to/ndk-directory |
| ``` |
| |
| From this directory, run: |
| |
| ```sh |
| go install golang.org/x/mobile/cmd/gomobile@latest |
| go install golang.org/x/mobile/cmd/gobind@latest |
| |
| # Make sure `gomobile` and `gobind` is in your `PATH`. |
| gomobile bind -o app/ivy.aar robpike.io/ivy/mobile |
| ``` |
| |
| Open this directory from Android Studio, and build. |
| |
| `robpike.io/ivy` and `golang.org/x/mobile` are required dependencies of this main module. In order to update them: |
| |
| ``` |
| go get -d golang.org/x/mobile@latest |
| go get -d robpike.io/ivy/mobile |
| go mod tidy |
| ``` |
