# Tailscale Android Client

Private WireGuard® networks made easy

## Overview

This repository contains the open source Tailscale Android client.

## Using

Available on [Play Store](https://play.google.com/store/apps/details?id=com.tailscale.ipn).

## Building

[Go](https://golang.org), the [Android
SDK](https://developer.android.com/studio/releases/platform-tools), 
the [Android NDK](https://developer.android.com/ndk) are required.

```
$ make tailscale-debug.apk
$ adb install -r tailscale-debug.apk
```

The `dockershell` target builds a container with the necessary
dependencies and runs a shell inside it.

```
$ make dockershell
# make tailscale-debug.apk
```

We only guarantee to support the latest Go release and any Go beta or
release candidate builds (currently Go 1.14) in module mode. It might
work in earlier Go versions or in GOPATH mode, but we're making no
effort to keep those working.

## Google Sign-In

Google Sign-In support relies on configuring a [Google API Console
project](https://developers.google.com/identity/sign-in/android/start-integrating)
with the app identifier and [signing key
hashes](https://developers.google.com/android/guides/client-auth).
The official release uses the app identifier `com.tailscale.ipn`;
custom builds should use a different identifier.

## Bugs

Please file any issues about this code or the hosted service on
[the tailscale issue tracker](https://github.com/tailscale/tailscale/issues).
