## 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
|
||
|
|
```
