Ivy Big Number Calculator (Android)

Ivy (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.

How to build

Requirements

• Go 1.17 or newer
• Android SDK
• Android NDK
• golang.org/x/mobile/cmd/gomobile

The gomobile command uses ANDROID_HOME and ANDROID_NDK_HOME environment variables.

export ANDROID_HOME=/path/to/sdk-directory
export ANDROID_NDK_HOME=/path/to/ndk-directory

Note: Both ANDROID_SDK_ROOT and ANDROID_NDK_HOME are deprecated in Android tooling, but gomobile still uses it. In many cases, ANDROID_HOME corresponds to the new ANDROID_SDK_ROOT. If you installed NDK using Android Studio's SDK manager, use the $ANDROID_SDK_ROOT/ndk/<ndk-version>/ directory as ANDROID_NDK_HOME (where <ndk-version> is the NDK version you want to use when compiling robpike.io/ivy for Android.

(TODO: update gomobile to work with modern Android layout)

From this directory, run:

  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
