A swig Java interface for libtorrent.

Download the latest JAR or get the dependency via Maven:

<dependency>
  <groupId>org.libtorrent4j</groupId>
  <artifactId>libtorrent4j</artifactId>
  <version>2.x.x</version>
</dependency>

or Gradle:

compile 'org.libtorrent4j:libtorrent4j:2.x.x'

If you use ProGuard to obfuscate/minify make sure to add the following statement

-keep class org.libtorrent4j.swig.libtorrent_jni {*;}

Note that there are multiple versions of libtorrent4j for different platforms:

libtorrent4j
libtorrent4j-android-<arch>
libtorrent4j-macos
libtorrent4j-linux
libtorrent4j-windows

These are all different artifacts, you need to select according to your architecture.

For examples look at demos and tests.

Architectures supported:

• Android (armeabi-v7a, arm64-v8a, x86, x86_64)
• macOS (x86_64)
• Linux (x86_64)
• Windows (x86_64)

This library tracks libtorrent master branch. The branch is very stable, runs a lot of tests, and receives bug fixes quickly.

It's possible to build android binaries locally. The solution is docker based, you need to have Docker installed and running (see https://docs.docker.com/engine/install/).

Go to the folder swig/android-build and perform all the operations inside it.

1 - Build the docker image just one time (takes a long time):

docker build -t lt4j:latest .

2 - Select your architecture and run the build script, for example:

./build-arm.sh

3 - Collect the jars in build/libs at the root of the project. Repeat the step 2) for the desired architectures.
