TDLight Java

A barebone java wrapper for TDLib (and TDLight)

This wrapper gives you direct access to TDLib API in Java.

Requirements

JVM: Oracle JVM or OpenJDK

Java versions: Java 8, 9, 10, 11, 12, 13, 14, 15

Operating system: Linux, Windows, macOS

Supported CPU architectures: amd64 (linux, windows, macos), aarch64 (linux)

Required libraries for linux: OpenSSL and zlib

Including TDLight Java in a project

There are two packages of TDLight:

• TDLight, with our optimized fork of TDLib (Reccomended for bots)
• TDLight with official TDLib (Reccomended for GUI clients)

The two packages are compatible, but while TDLight is focused on long term resources usage and speed, TDLib is more focused on stability.

Choose one of the two different TDLight packages and then follow the guide below.

Replace REPLACE_WITH_LATEST_VERSION with the latest version of tdlight, you can find it on the Releases tab on github.

Natives inclusion

To use TDLight java for a specific platform, you need to include the related native dependencies:

• tdlight-natives-linux-amd64
• tdlight-natives-linux-aarch64
• tdlight-natives-linux-x86
• tdlight-natives-linux-armv6
• tdlight-natives-linux-armv7

Usage

Simple initialization of a native TDLib client

package it.tdlight.example;

import it.tdlight.common.TelegramClient;
import it.tdlight.tdlight.ClientManager;
import it.tdlight.common.Init;
import it.tdlight.common.Log;
import it.tdlight.common.TDLibException;

import it.tdlight.jni.TdApi;

public class Example {
    public static void main(String[] args) {
        // Initialize TDLight native libraries
        Init.start();

        // Create a client
        TelegramClient client = ClientManager.create(Example::onUpdate, Example::onUpdateError, Example::onError);

        // Here you can use the client.

        // Documentation of tdlib methods can be found here:
        // https://tdlight-team.github.io/tdlight-docs

        // A similar example on how to use tdlib can be found here:
        // https://github.com/tdlib/td/blob/master/example/java/org/drinkless/tdlib/example/Example.java
    }

    private static void onUpdate(TdApi.Object object) {
        TdApi.Update update = (TdApi.Update) object;
        System.out.println("Received update: " + update);
    }

    private static void onUpdateError(Throwable exception) {
        if (exception instanceof TDLibException) {
        	String errorMessage = ((TDLibException) exception).getErrorMessage();
            System.out.println("Received an error from updates: " + errorMessage);
        } else {
            System.out.println("Received an error from updates:");
            exception.printStackTrace();
        }
    }

    private static void onError(Throwable exception) {
        if (exception instanceof TDLibException) {
        	String errorMessage = ((TDLibException) exception).getErrorMessage();
            System.out.println("Received an error: " + errorMessage);
        } else {
            System.out.println("Received an error:");
            exception.printStackTrace();
        }
    }
}
