我已经从here克隆了Telegram源代码，并且尝试构建该项目，但是遇到以下错误（我正在使用Ubuntu 19.04）：
Build command failed.
Error while executing process /home/user/Android/Sdk/ndk-bundle/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/home/user/StudioProjects/Telegram/TMessagesProj/jni/Android.mk NDK_APPLICATION_MK=/home/user/StudioProjects/Telegram/TMessagesProj/jni/Application.mk APP_ABI=x86 NDK_ALL_ABIS=x86 NDK_DEBUG=0 APP_PLATFORM=android-16 NDK_OUT=/home/user/StudioProjects/Telegram/TMessagesProj/build/intermediates/ndkBuild/afat/release/obj NDK_LIBS_OUT=/home/user/StudioProjects/Telegram/TMessagesProj/build/intermediates/ndkBuild/afat/release/lib NDK_APPLICATION_MK:=jni/Application.mk APP_PLATFORM:=android-16 -j8 /home/user/StudioProjects/Telegram/TMessagesProj/build/intermediates/ndkBuild/afat/release/obj/local/x86/libtmessages.30.so}
我已经在local.properties中设置了ndk和skd路径，如下所示，我确定它们是正确的：
ndk.dir=/home/user/Android/Sdk/ndk-bundle
sdk.dir=/home/user/Android/Sdk
我已经在整个互联网上进行搜索，但是找不到解决方案。有人认识吗？
