A swig Java interface for libtorrent. Source code fork from jlibtorrent.

Download the latest JAR or get the dependency via Maven:

<dependency>
  <groupId>org.libtorrent4j</groupId>
  <artifactId>libtorrent4j</artifactId>
  <version>1.2.x.x</version>
</dependency>

or Gradle:

compile 'org.libtorrent4j:libtorrent4j:1.2.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 version of libtorrent4j for different platforms: libtorrent4j, libtorrent4j-windows, libtorrent4j-linux, libtorrent4j-macosx and libtorrent4j-android-<arch>. These are all different artifacts.

For examples look at demos.

Architectures supported:

• Android (armeabi-v7a, arm64-v8a, x86, x86_64)
• Linux (x86, x86_64)
• Windows (x86, x86_64)
• Mac OS X (x86_64)

You need:

• Setup a travis account at http://travis-ci.org and get familiar with the service if necessary.
• Open an account with Amazon Web Services (AWS) and get familiar with S3 (for storage) and IAM (for users).
• Some familiarity with git commands.

The process is:

• Create a user in amazon IAM, let's suppose it is user1. Download credentials for the keys.
• Create a bucket in amazon S3, let's suppose it is libtorrent4j1.
• Set the permission of the bucket according to your workflow, but at least the user1 should have permission to put/upload to the bucket. See for example this bucket policy:

{
	"Statement": [
		{
			"Effect": "Allow",
			"Principal": {"AWS":"arn:aws:iam::<user1's ARN here>:user/user1"},
			"Action": "s3:PutObject",
			"Resource": "arn:aws:s3:::libtorrent4j1/*"
		},
		{
			"Effect": "Allow",
			"Principal": "*",
			"Action": "s3:GetObject",
			"Resource": "arn:aws:s3:::libtorrent4j1/*"
		}
	]
}

• Fork the project in github.
• Go to travis and enable the repository.
• Go to 'More options' > 'Settings' > 'Environment Variables' and set the S3_ACCESS_KEY, S3_SECRET_KEY, S3_BUCKET variables using the values in the credentials file for the user you created and the bucket name you created.
• Clone locally your repo, let's assume to the libtorrent4j folder and checkout the stable branch:

$ git clone <your fork repo url> libtorrent4j
$ cd libtorrent4j
$ git checkout master

• Verify in your travis online if the build already started. The build could take about 40 minutes, be patient.
• When finished, check your s3 bucket for the binaries.
• To trigger a new build, just make a change or merge new changes from the stable branch, commit and push.
