Telegram github地址

github: https://github.com/DrKLO/Telegram.git

编译环境

Windows 64
Android studio 4.2
ndk版本：21.1.6352462
JDK1.8

准备工作

去telegram官网下载app，注意需要vpn才能连接到，app也同样需要vpn才可以使用。
使用手机号登录telegram app
打开https://my.telegram.org/,输入刚才在app内登录的账号如 +8618312345678，点击NEXT获取验证码，验证码会发到app内，
登录后打开 API development tools，填写app名称，和shortname，比如 testapp1,选择Android，最后点击 Create application 创建完成

开始编译

拉取代码

git clone https://github.com/DrKLO/Telegram.git

检出7.6.1

我们的项目目前使用到群语音版本 7.6.1,如果是连接的是telegram的服务，不需要做服务端的，如果想自己做服务端的接口，去参考官方的api标准，
我们的app服务端是自己做的，所以群语音也需要自己做，后面会出一个自己做的群语音服务的教程，基于mediasoup，以及官方的Demo讲解。

git checkout 7ba9838a

Android studio打开telegram项目

编辑Telegram\TMessagesProj\src\main\java\org\telegram\messenger\BuildVars.java
替换你在控制台创建的获取的 APP_ID 和 APP_HASH
下面是对应修改的代码

public class BuildVars {public static boolean DEBUG_VERSION = BuildConfig.DEBUG;public static boolean DEBUG_PRIVATE_VERSION = DEBUG_VERSION;public static boolean LOGS_ENABLED = DEBUG_VERSION;public static boolean USE_CLOUD_STRINGS = true;public static boolean CHECK_UPDATES = true;public static int BUILD_VERSION = BuildConfig.VERSION_CODE;public static String BUILD_VERSION_STRING = BuildConfig.VERSION_NAME;public static int APP_ID = 1;//你的api_idpublic static String APP_HASH = "你的api_hash";//由于要在谷歌商店，必须去掉所有APPCENTER相关的库，否则被拒//public static String APPCENTER_HASH = "a5b5c4f5-51da-dedc-9918-d9766a22ca7c";//public static String APPCENTER_HASH_DEBUG = "f9726602-67c9-48d2-b5d0-4761f1c1a8f3";public static String SMS_HASH = DEBUG_VERSION ? "O2P2z+/jBpJ" : "oLeq9AcOZkT";public static String PLAYSTORE_APP_URL = "https://play.google.com/store/apps/details?id=org.telegram.messenger";static {if (ApplicationLoader.applicationContext != null) {SharedPreferences sharedPreferences = ApplicationLoader.applicationContext.getSharedPreferences("systemConfig", Context.MODE_PRIVATE);LOGS_ENABLED = sharedPreferences.getBoolean("logsEnabled", DEBUG_VERSION);}}
}

去除一些代码

AndroidManifest.xml中删除android:manageSpaceActivity=“org.telegram.ui.ExternalActionActivity”，防止想清除数据而没法进入系统清除的界面
全局搜索 protectionLevel=“signature” 并删除防止手机上装了telegram而权限冲突安装失败

<permission android:name="org.telegram.messenger.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

运行项目

到此项目应该会成功运行，运行完成即可登录到telegram正式服务器

如果想看tg的数据，打印log日志查看

添加依赖库

implementation 'org.apache.commons:commons-lang3:3.6'

创建RecursiveToStringStyle.java，将tg数据转为字符串并格式化

}

在Telegram\TMessagesProj\src\main\java\org\telegram\messenger\MessagesController.java中修改
在Telegram\TMessagesProj\src\main\java\org\telegram\tgnet\ConnectionsManager.java中修改
由于log过长可能打印不全，修改Telegram\TMessagesProj/src/main/java/org/telegram/messenger/FileLog.java

至此可以快乐地抓取tg数据了

接收离线推送（谷歌推送）

打开 https://console.firebase.google.com/ 注册一个账号
创建一个项目 telegram，项目创建完成后添加两个安卓应用org.telegram.messenger 和 org.telegram.messenger.beta
build.gradle里替换为你的签名文件，打开项目设置，为两个应用分别添加SHA证书，SHA1和SHA256，如何获取SHA证书，看下面
打开Android studio右侧的Gradle
在firebase控制台，项目配置-》云消息传递，复制密钥，然后打开https://my.telegram.org/apps，配置GCM API key，就是刚才复制的key保存就ok了

注意

如果想编译其他版本，低于 7.1.0 的版本windows上是编译不了的，因为目录太长，超过了windows的最大长度限制，解决办法，下载 VMware 创建ubuntu虚拟机，编译过程都是一样的
