+## 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
+```
