Using

Download the latest release .jars

All platforms will need you to use at least 2 .jar files.

The .jar with the java classes -> jlibtorrent-w.x.y.z.jar and a secondary .jars containing the JNI binary library for the particular OS and CPU architecture.

In the case of desktop operating systems, you might want to extract the shared library inside the jar (.dll, .so, .dylib) and place it in a folder specified by the java.library.path

The secondary jars are:

Windows: jlibtorrent-windows-w.x.y.z.jar (x86 and x86_64 .dlls)
Mac: jlibtorrent-macosx-w.x.y.z.jar (x86_64 .dylib)
Linux: jlibtorrent-linux-w.x.y.z.jar (x86 and x86_64 .so)

In the case of Android, make sure to put the following 5 jars in your project's libs folder (see FrostWire for Android's as an example):

jlibtorrent-w.x.y.z.jar
jlibtorrent-android-arm-w.x.y.z.jar
jlibtorrent-android-arm64-w.x.y.z.jar
jlibtorrent-android-x86-w.x.y.z.jar
jlibtorrent-android-x86_64-w.x.y.z.jar

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

-keep class com.frostwire.jlibtorrent.swig.libtorrent_jni {*;}

Note that there are multiple version of jlibtorrent for different platforms: jlibtorrent, jlibtorrent-windows, jlibtorrent-linux, jlibtorrent-macosx and jlibtorrent-android-<arch>. These are all different artifacts.

For examples look at https://github.com/frostwire/frostwire-jlibtorrent/tree/master/src/test/java/com/frostwire/jlibtorrent/demo

Architectures supported:

Android (armeabi-v7a, arm64-v8a, x86, x86_64) sdk 24 (Android 7.0) and up
Linux (x86_64)
Windows (x86_64)
Mac OS X (x86_64)

Building

To build the macos (x86_64) binaries you will need a mac computer, to build the mac library issue the following command:

cd swig && ./build-macos.sh

To build the windows (x86_64), linux (x86_64) and android binaries (arm, arm64, x86, x86_64) you will need a working version of Docker, then just issue the following command

cd swig && ./docker_build_binaries.sh

The resulting jars will be at:

./build/libs/jlibtorrent-w.x.y.z.jar
./build/libs/jlibtorrent-windows-w.x.y.z.jar
./build/libs/jlibtorrent-macos-w.x.y.z.jar
./build/libs/jlibtorrent-linux-w.x.y.z.jar
./build/libs/jlibtorrent-android-arm-w.x.y.z.jar
./build/libs/jlibtorrent-android-arm64-w.x.y.z.jar
./build/libs/jlibtorrent-android-x86-w.x.y.z.jar
./build/libs/jlibtorrent-android-x86_64-w.x.y.z.jar

If you need the singled out .so,.dylib and .dll files and their .debug versions they will be at:

./swig/bin/release/windows/x86_64/jlibtorrent.dll
./swig/bin/release/macosx/x86_64/libjlibtorrent.dylib
./swig/bin/release/linux/x86_64/libjlibtorrent.so
./swig/bin/release/android/armeabi-v7a/libjlibtorrent.so
./swig/bin/release/android/arm64-v8a/libjlibtorrent.so
./swig/bin/release/android/x86/libjlibtorrent.so
./swig/bin/release/android/x86_64/libjlibtorrent.so

frostwire-jlibtorrent's Issues

Android libjlibtorrent.so cross-compile ARM build instructions

You guys rock!!!
I have jlibtorrent working wonderfully in my Android App.
And for that, I think you. (documentation was great)

I love the build scripts...so helpful.
I am attempting to build libjlibtorrent.so (libtorrent)
Step 1: get libtorrent sources
Step 2: set all environment variables
Step 3: run_swig.sh
Step 4: build_android.sh

Is this the correct order?

Getting missing file errors.
QUESTION: which libtorrent source version? 1.0.2, 1.0.4, latest?

Compiling on OSX Yosemite.

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jlibtorrent in java.library.path

Sorry for beeing a noob, but Im having issues getting "System.out.println("Using libtorrent version: " + LibTorrent.version());" run.

I have included everything in src so that all imports looks ok in Eclipse, but I have no idea how to do the build stuff, can I use the provided binaries or do I have to build something myself? It says "The result will be a libjlibtorrent.dylib", and thats provided in the rep. But how do I use it?

This is my code:

import java.io.File;
import java.util.concurrent.CountDownLatch;

import com.frostwire.jlibtorrent.LibTorrent;
import com.frostwire.jlibtorrent.Session;
import com.frostwire.jlibtorrent.TorrentAlertAdapter;
import com.frostwire.jlibtorrent.TorrentHandle;
import com.frostwire.jlibtorrent.alerts.BlockFinishedAlert;
import com.frostwire.jlibtorrent.alerts.TorrentFinishedAlert;

public class Main {

    public static void main(String[] args) {
        System.out.println("Using libtorrent version: " + LibTorrent.version());
    }

}

And this is the complete error message:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jlibtorrent in java.library.path

Missing plugin interface

It appears that the plugin interface is not present in this version of jlibtorrent?

For the swig classes, the session does not have add_extension(), and the classes
plugin, torrent_plugin and peer_plugin are missing entirely.

This morning they were present, but the jlibtorrent_jni class did not implement all the required function calls to support the three classes.

Does jlibtorrent presently support the plugin interface, and what are the plans pertaining to this?

How to save a torrent file?

I can't for the life of me figure out how to save a torrent file with jlibtorrent.

I've looked at the two examples CreateTorrentTest, and CreateTorrentTest2.java, and they both seem to create com.frostwire.jlibtorrent.swig.entry, but I have no idea how to write this to an output stream.

I also see entry.bencode() [char_vector], but wouldn't know how to write a char_vector using java like this. Could you provide an example, using an outputstream or something?

file_storage fs = new file_storage();

        // Add the file
        libtorrent.add_files(fs, si.getFile().getAbsolutePath());

        create_torrent t = new create_torrent(fs);
        for (URI announce : DataSources.ANNOUNCE_LIST()) {
            log.info(announce.getPath());
            log.info(announce.getRawPath());
            t.add_tracker(announce.getPath());
        }

        t.set_creator(System.getProperty("user.name"));

        error_code ec = new error_code();


        // reads the files and calculates the hashes
        libtorrent.set_piece_hashes(t, si.getFile().getParent(), ec);

        if (ec.value() != 0) {
            log.info(ec.message());
        }

        entry e = t.generate();

Magnet-links

Magnet links are not working anymore, problem seems to be in: "torrent_handle th = s.getSwig().find_torrent(info_hash)" in Downloader.java

Missing torrent::request_time_critical_pieces()

Can you tell me when you plan on adding this function?

Strange QueuedThreadPool exception, UnknownError: Success

I occasionally get a strange exception when I run:

TorrentHandle torrent = session.addTorrent(torrentFile, outputParent);

What could be causing it?

Add libtorrent benchmarking to jlibtorrent

Would it be possible to add libtorrent's session benchmarking logs as shown here ? It would really help to diagnose any problems with jlibtorrent in general.

where is the gradle script?

In the readme,

Building the frostwire-jlibtorrent.jar

inside the build/ folder just invoke gradle build

you will find the resulting frostwire-jlibtorrent.jar at build/build/libs/frostwire-jlibtorrent.jar.

But I could not find the gradle script.

Another crash

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007f340c2eb0d0, pid=16604, tid=139861386065664

Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

If you would like to submit a bug report, please visit:
http://bugreport.java.com/bugreport/crash.jsp
The crash happened outside the Java Virtual Machine in native code.
See problematic frame for where to report the bug.

Any tips how to reduce the crashes? Should I test with Java 8?

arm64 for Android

Is there any chance you'll ever add arm64 library for Android to the maven distribution? I'm currently splitting my APK's by architecture to make sure it doesn't become huge (I use another native lib), but the arm64 version doesn't work without a arm64 library.

Architecture Binary Error

Hello Frostwire,
Exception in thread "main" java.lang.UnsatisfiedLinkError: Look for your architecture binary instructions at: https://github.com/frostwire/frostwire-jlibtorrent

I am getting this error, which i thought would have been a wrong version or OS , got the Jar from the releases tab on GitHub which i then decided to build it with gradle build nativWindowsJar (please correct me if i am wrong) after getting the exception, but am still getting the same error, I am running Windows 8, 64 Bit. Am i doing anything wrong here which would result in this error ?

Thank You For Your Help.

Torrent_finished alerts not firing

I've notice that occasionally, a torrent will be shown to be 100% downloaded, yet will not fire a torrent_finished alerts. It only happens sometimes.

Could you guys think of a possible cause of this? I've been stumped so far.

[Crash] signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 099bf868

Background:

This issue seems to happen quite frequently without any warning. I tried using the addr2line utility and came up with no possible leads. Hopefully this is helpful.

I'm using the gradle maven repo:

compile 'com.frostwire:jlibtorrent:1.1.0.0'
compile 'com.frostwire:jlibtorrent-android:1.1.0.0'

Let me know if you need anything else from me.

Getting seeders and leechers count

Hello Frostwire,

I cannot seem to find this anywhere(in the source), i would love to know, how would one find the number of seeders and leechers from a magnet link ?

Thank You for reading.

Add SESSION_STATS to jlibtorrent

@arvidn is asking me for session stats instead ...

From here : arvidn/libtorrent#63 (comment)

you get session stats by building with statistics=on (if building with boost-build) or defining TORRENT_STATS

Some torrents getting stuck on CHECKING_FILES state

I'm finding that after running torrent.resume(), some of my torrents are getting stuck in the CHECKING_FILES state, and never continue on to the seeding state.

What could cause that to happen?

Ability to instantiate jlibtorrent using a custom binary/library path.

Its much much easier, instead of trying to fiddle around with the java.library.path, to use the following code in libtorrent_jni.java to load the correct jlibtorrent binary. In other words, setting the binary path explicitly in code as opposed to using command line params.

For example, my program works for mac, linux, and windows, simply by returning the correct binary:

System.loadLibrary("jlibtorrent"); // Get rid of this line
System.load(DataSources.LIBTORRENT_OS_LIBRARY_PATH()); // Chooses the correct binary depending on the system OS.

And you guys could create a general constructor, that can optionally use that path:

LibTorrent.setup(LOCATION_OF_BINARY);
System.out.println(LibTorrent.version());

How to edit and save a .torrent file(Just for reference).

So I just wanted to post the question and answer for a problem I just figured out how to solve. You guys might think it worth adding to the examples.

I needed to change the tracker on a ton of my .torrent files, since demonii got shut down, and my torrent's only have 1 tracker and no DHT(for network reasons... there are thousands of them.)

Anyway, here's the method for how to do this:

public static void updateTrackerForTorrent(File torrentFile) {

        TorrentInfo ti = new TorrentInfo(torrentFile);

        create_torrent t = new create_torrent(ti.getSwig());

        // Changing the tracker
        for (URI announce : DataSources.ANNOUNCE_LIST()) {
            t.add_tracker(announce.toASCIIString());
        }


        // Get the bencode and write the file
        Entry entry =  new Entry(t.generate());

        Map<String, Entry> entryMap = entry.dictionary();
        Entry entryFromUpdatedMap = Entry.fromMap(entryMap);
        final byte[] bencode = entryFromUpdatedMap.bencode();

        FileOutputStream fos;

        try {
            fos = new FileOutputStream(torrentFile);

            BufferedOutputStream bos = new BufferedOutputStream(fos);
            bos.write(bencode);
            bos.flush();
            bos.close();

            log.info("Trackers updated for torrent: " + torrentFile.getName());
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

MillionTorrentTester

@aldenml I've worked up the torrent tester example. I'm not sure a pull request would be the best way to give it to you, so I'll just put the code for the class here.

I'd highly suggest also adding the createAndSaveTorrent(or portions of it) into jlibtorrent, because its very useful.

Apologies in advance for the verbose amount of listeners, but IMO its better than the tick.

build.gradle is using unset ossrhUsername and ossrhPassword properties

There is a problem on lines #137 and #141 in build.gradle file; unset properties are used for authentication that lead to error when executing the Gradle build.

Suggest the following fix (for both lines):

authentication( userName: hasProperty('ossrhUsername')?ossrhUsername:'', password: hasProperty('ossrhPassword')?ossrhPassword:'' )

I'm just trying to print an Entry, be it using libtorrent.print_entry(lazy_entry le) or by trying to obtain the bencoded value of it via entryJavaWorldObject.bencode()

However, I can't get past that first step when I'm making a mock (C++ to java) entry object.

Make frostwire-jlibtorrent available on Maven.

If anybody watching has already gone through this process any help/tips would be appreciated to get the library up there as soon as possible.

A proper way to load multiple torrents?

Hello. Let's says I have a TorrenManager class which contains a addTorrent() method(see below) If I want to add more torrents do I need to create new Session and Downloader? Or jsut use previous one?

public void addTorrent () throws Throwable{
  Session s = new Session();
   Downloader d = new Downloader(s);
   DHT dht = new DHT(s);
 File torrentFile = new File(getAppContext().getFilesDir()+"/temp.torrent");
                    final TorrentHandle th = s.addTorrent(torrentFile, new File( Environment.getExternalStorageDirectory() + "/"+ torrentFile.getParentFile()));
                    final CountDownLatch signal = new CountDownLatch(1);
                    s.addListener(new TorrentAlertAdapter(th) {
                        @Override
                        public void blockFinished(BlockFinishedAlert alert) {
                            int p = (int) (th.getStatus(true).getProgress() * 100);
                            progress=p;
                            System.out.println("Progress: " + p + " for torrent name: " + alert.torrentName());
                           // System.out.println(s.getStats().download());
                        }

                        @Override
                        public void torrentFinished(TorrentFinishedAlert alert) {
                            System.out.print("Torrent finished");
                            int p = (int) (th.getStatus(true).getProgress() * 100);
                            progress=p;
                            System.out.println("Progress: " + p + " for torrent name: " + alert.torrentName());


                            signal.countDown();
                        }
                    });

                    th.resume();

                    signal.await();
}

How to turn on PeerLog alerts/ Peer Logging?

@arvidn is recommending that I do some logging of PeerLog, and I have the code to do them, but I don't know how to turn the logging on.

He told me :

In 1.1.0 you don't need to rebuild libtorrent to enable verbose peer logging, they are alerts now that can be enabled with an alert mask flag.

Here's my code thats not doing anything :(

        session.addListener(new AlertListener() {

            @Override
            public int[] types() {
                return new int[]{AlertType.SESSION_STATS.getSwig(), AlertType.PEER_LOG.getSwig()};

            }
@Override
public void alert(Alert<?> alert) {
   if (alert instanceof PeerLogAlert) {
                        log.debug("peer log alert");
                        log.debug(alert.getType() + " - " + alert.getSwig().what() + " - " + alert.getSwig().message());
                        log.debug(((PeerLogAlert) alert).eventType());
                        log.debug(((PeerLogAlert) alert).direction().toString());
                        log.debug(((PeerLogAlert) alert).getPeerId().toString());
                        log.debug(((PeerLogAlert) alert).getPeerIP().toString());
                    }

Building for linux(ubuntu)

The build instructions for linux are a bit unclear, and I'm having some problems.

So i downloaded libtorrent-rasterbar-1.0.5, (had to install boost as well for ubuntu which was unforeseen), ran make and make install, and it installed fine.

The run_swig.sh script didn't work in its directory, and neither did build_linux.sh.

I have no idea where the libtorrent root directories or libtorrent library dirs on my system should be. I'm running ubuntu.

run_swig [swig-error] Error: 'new_feed' is multiply defined in the generated target language module in scope 'libtorrentJNI'.

SIGSEGV on Android

So I tried to replace my previous version of jlibtorrent binaries and library code by the maven repositories in Gradle.

Can something be wrong with the binaries? The previous version worked perfectly and this is what's happening now:

08-07 11:21:44.092 29229-29412/pct.droid.dev A/libc﹕ Fatal signal 11 (SIGSEGV), code 1, fault addr 0xe02fa40 in tid 29412 (Session-alertsL)

I first thought that it happened after I added my second listener. But it doesn't. Debugging in Android Studio tells me that some blocks are being finished. And then suddenly some alert comes (I guess, looking at the error) and the app crashes.

How to set enum types of SettingsPack settings?

I'm trying to get jlibtorrent to prefer TCP over uTP, and I ned to set Bandwidth_Mixed_Algo, or Mixed_Mode_Algorithm to prefer TCP.

I used to be able to do sessionSettings.setMixedModeAlgorithm(BandwidthMixedAlgo.PEER_PROPORTIONAL);

How do I do this now?

Download Torrent on Android

I'm trying to download a .torrent with frostwire-jlibtorrent library. I copy the sources directly in my project source folder like https://github.com/frostwire/frostwire-jlibtorrent says and I did a simple Activity to run it on a phone. I have no errors doing that but the download never starts. I used the example code from github frostwire and nothing.

I don't understand what I'm doing wrong. The source code is this:

File torrentFile = new File("/sdcard/torr.torrent");

System.out.println("Using libtorrent version: " + LibTorrent.version());

final Session s = new Session();

final TorrentHandle th = s.addTorrent(torrentFile, torrentFile.getParentFile());

final CountDownLatch signal = new CountDownLatch(1);

s.addListener(new TorrentAlertAdapter(th) {
    @Override
    public void onBlockFinished(BlockFinishedAlert alert) {
        int p = (int) (th.getStatus().getProgress() * 100);
        System.out.println("Progress: " + p);
    }

    @Override
    public void onTorrentFinished(TorrentFinishedAlert alert) {
        System.out.print("Torrent finished");
        signal.countDown();
    }
});

th.resume();

signal.await();

I can see the torrent data, like name or the files inside it but I can't download it.

Please help I really need it :/

Problems with frostwire-jlibtorrent-linux artifact(libjlibtorrent.so) on linux kernel versions 4.x

I'm currently using the pre-built linux libjlibtorrent.so version 1.1.0.6 from here:

http://mvnrepository.com/artifact/com.frostwire/jlibtorrent-linux

Someone running my client is getting the following error(on kernel version 4.1.6-200.fc22.x86_64):

Exception in thread "main" java.lang.UnsatisfiedLinkError: Look for your architecture binary instructions at: https://github.com/frostwire/frostwire-jlibtorrent

I think we've narrowed it down to a linux kernel version issue: I have many of these clients running on various versions of linux 3.x, but hadn't tried 4.x yet.

What would be the best way to solve this issue?

[CRASH] libtorrent::piece_picker::add(int) / SIGFPE (Arithmethic Error)

Application version: 1.6.3 (current staged rollout)
Android version: Android 5.0
Device: Galaxy Note4 (tritecan)

The SIGFPE signal reports a fatal arithmetic error. Although the name is derived from “floating-point exception”, this signal actually covers all arithmetic errors, including division by zero and overflow. If a program stores integer data in a location which is then used in a floating-point operation, this often causes an “invalid operation” exception, because the processor cannot recognize the data as a floating-point number.

Right after it builds (with clang, can't build with g++ anymore for some unknown reason)

Windows 64 bit support?

I'm noticing that one of my clients trying to run jlibtorrent with the jlibtorrent.dll from the maven/gradle x86/ folder isn't working. They're currently running Windows 10 64-bit. Would it be possible to add the 64 bit version to that maven/gradle build as well?

dessalines/torrenttunes-client#13

I've tested the jlibtorrent and it does work fine for windows 32 bit.

dht_put_mutable_item and callbacks.

Was looking at session_impl::dht_put_mutable_item and in the C++ world this function takes a callback function as a parameter.

somehow that callback gets bound to a session_impl::put_mutable_callback (I wonder if this binding, is the same as saying that the given callback must implement the interface of the bound function...anyways)

it'd be really nice to have a similar callback mechanism in jlibtorrent and I wonder if it can be done using Java interfaces, the code in C++ looks like this (session_impl.cpp)

void put_mutable_callback(
    alert_manager& alerts, 
    dht::item& i, 
    boost::function<void(entry&, 
                         boost::array<char,64>&,
                         boost::uint64_t&, 
                         std::string const&)> cb)
{
    entry value = i.value();
    boost::array<char, 64> sig = i.sig();
    boost::array<char, 32> pk = i.pk();
    boost::uint64_t seq = i.seq();
    std::string salt = i.salt();
    cb(value, sig, seq, salt);
    i.assign(value, salt, seq, pk.data(), sig.data());

    if (alerts.should_post<dht_put_alert>())
        alerts.post_alert(dht_put_alert(pk, sig, salt, seq));
}

void session_impl::dht_put_mutable_item(
    boost::array<char, 32> key,
    boost::function<void(entry&, boost::array<char,64>&,
    boost::uint64_t&, std::string const&)> cb,
    std::string salt)
{
    if (!m_dht) return;

    m_dht->put_item(key.data(), 
                    boost::bind(&put_mutable_callback, 
                                boost::ref(m_alerts), 
                                _1, 
                                cb), 
                    salt);
}

DHT and PEX features enabled by default?

Hey, so I'm using the frontpage example, or here: https://github.com/frostwire/frostwire-jlibtorrent/blob/a367e8f845f501c533ceaf33cf44ebea814198d0/src/com/frostwire/jlibtorrent/demo/DownloadTorrent.java

Are the DHT and PEX features are enabled by default? Am I getting all the peers I should be?

Does anyone know of a more complicated downloader example that has these features?

build/ folder and binaries are missing

I've noticed the build folder is gone, and also, none of the build shell scripts in the swig/ folder work. So I'm unable to get libtorrent 1.1.0.1-3 working.

How to set custom swig settings in a SettingsPack correctly?

Here's how I'm currently doing it, and I have no idea if its working or not:

session = new Session();
sessionSettings = new SettingsPack();

sessionSettings.setActiveSeeds(999999);
sessionSettings.setInteger(int_types.active_limit.swigValue(), 999999); // this line

session.applySettings(sessionSettings);

LibTorrent.version()

Under Windows it gives me this result: 1.1.0.0

I am confused because I expect a version like 1.0.7.

Is it a bug or do you work with an unstable version of libtorrent?

session.AddTorrent flags

Based on arvid's recommendations, I need to set seed_mode=true on a torrent added to the session.

I see the addTorrentParams method, but wouldn't it be better to use it like so?

TorrentHandle torrent = session.addTorrent(File torrent, File saveDir, File saveResumeData, Set<TorrentFlagEnum> flags);

If not, could you give me an example of how to set those parameters while adding a torrent with swig?
