Psiphon Android Library README

Overview

Psiphon Library for Android enables you to easily embed Psiphon in your Android app.

Using the Library

If building from source

1. Build ca.psiphon.aar from via the docker container.
2. Add ca.psiphon.aar to your Android Studio project as described in the gomobile documentation

If using Maven based binary distribution

1. Add maven repo to your app build.gradle

   repositories {
   ...
   maven {
       url "https://raw.github.com/Psiphon-Labs/psiphon-tunnel-core-Android-library/master"
   }
   }
   

   then add PsiphonTunnel dependency like following

   dependencies {
   ...
   implementation 'ca.psiphon:psiphontunnel:x.y.z'
   }
   

   Where x.y.z is the target version. Latest available release version can be found at https://github.com/Psiphon-Labs/psiphon-tunnel-core-Android-library

See example usage in TunneledWebView sample app

Building with Docker

Note that you may need to use sudo docker below, depending on your OS.

Create the build image:

1. While in the MobileLibrary/Android directory, run the command: docker build --no-cache=true -t psiandroid -f Dockerfile ..

2. Once completed, verify that you see an image named psiandroid when running: docker images

Run the build:

Ensure that the command below is run from within the MobileLibrary/Android directory

The --user "$(id -u):$(id -g)" flag must be omitted when building on macOS because manually specifying the UID/GID will cause the build to fail since Docker on macOS handles host to container UID/GID mapping automatically and will be unable to map the manually specified UID/GID to the current user.

cd ../.. && \
  docker run \
  --platform=linux/amd64 \
  --user "$(id -u):$(id -g)" \
  --rm \
  -v $(pwd):/go/src/github.com/Psiphon-Labs/psiphon-tunnel-core \
  psiandroid \
  /bin/bash -c 'cd /go/src/github.com/Psiphon-Labs/psiphon-tunnel-core/MobileLibrary/Android && ./make.bash' \
; cd -

When that command completes, the compiled .aar files (suitable for use in an Android Studio project) will be located in the current directory (it will likely be owned by root, so be sure to chown to an appropriate user).

Building without Docker (from source)

Prerequisites:

• The build-essential package (on Debian based systems - or its equivalent for your platform)
• Go 1.15 or later
• Full JDK
• Android NDK
• Android SDK

Steps:

1. Follow Go Android documentation (gomobile documentation)
2. Run make.bash
