Using
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)
About stability
This library tracks libtorrent master branch.
The branch is very stable, runs a lot of tests, and receives bug fixes quickly.
Android local builds
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.
