如何解决我已经从GitHub下载了电报开源代码

构建命令失败。

Error while executing process /Users/nyame/Library/Android/sdk/ndk/21.1.6352462/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/Users/nyame/Documents/androidProjects/Telegram-FOSS/TMessagesProj/jni/Android.mk NDK_APPLICATION_MK=/Users/nyame/Documents/androidProjects/Telegram-FOSS/TMessagesProj/jni/Application.mk APP_ABI=armeabi-v7a NDK_ALL_ABIS=armeabi-v7a NDK_DEBUG=1 APP_PLATFORM=android-16 NDK_OUT=/Users/nyame/Documents/androidProjects/Telegram-FOSS/TMessagesProj/build/intermediates/ndkBuild/afatDebug/obj NDK_LIBS_OUT=/Users/nyame/Documents/androidProjects/Telegram-FOSS/TMessagesProj/build/intermediates/ndkBuild/afatDebug/lib NDK_APPLICATION_MK:=jni/Application.mk APP_PLATFORM:=android-16 --jobs=16 APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n}

这些是我尝试但不为我工作的步骤：

1. git子模块更新--init --recursive在libtgvoip文件夹中
2. 进行研究，但看起来我的问题有所不同。

这是我的android.mk文件，似乎无法提供libavutil.a文件的路径

MY_LOCAL_PATH := $(call my-dir)
LOCAL_PATH := $(MY_LOCAL_PATH)

LOCAL_MODULE    := avutil 

LOCAL_SHORT_COMMANDS := true

ifeq ($(TARGET_ARCH_ABI),armeabi-v7a)
    FFMPEG_INCLUDE_PATH := $(LOCAL_PATH)/ffmpeg/build/armv7-a/include
    LOCAL_SRC_FILES := ./ffmpeg/build/armv7-a/lib/libavutil.a
else ifeq ($(TARGET_ARCH_ABI),arm64-v8a)
    FFMPEG_INCLUDE_PATH := $(LOCAL_PATH)/ffmpeg/build/arm64-v8a/include
    LOCAL_SRC_FILES := ./ffmpeg/build/arm64-v8a/lib/libavutil.a
else ifeq ($(TARGET_ARCH_ABI),x86)
    FFMPEG_INCLUDE_PATH := $(LOCAL_PATH)/ffmpeg/build/i686/include
    LOCAL_SRC_FILES := ./ffmpeg/build/i686/lib/libavutil.a
else ifeq ($(TARGET_ARCH_ABI),x86_64)
    FFMPEG_INCLUDE_PATH := $(LOCAL_PATH)/ffmpeg/build/x86_64/include
    LOCAL_SRC_FILES := ./ffmpeg/build/x86_64/lib/libavutil.a
endif

解决方法

电报源代码使用一些语言（例如C和C ++），因此android studio gradle需要NDK（本机开发套件）来构建项目，我认为您的系统上没有NKD。
