求求了，谁能告诉我为什么import go.Seq import libcore.Libcore报错啊，有偿啊

[victorliuboom]

描述建议

根本运行不起来啊，怎么让go也能在android项目中，怎么编译啊

建议的必要性

[maskedeken]

你要用gomobile编译，参考libcore/build.sh这个脚本。把编译出来的aar文件放到app/libs下，再用gradlew编译

[dou23]

在Ubuntu中，你需要搭建完成的go环境，go最好是1.20以上，然后go要安装gomobile。 编译的命令是./run lib core。 先把环境弄好，然后跑一下这个命令，有啥问题不懂的再回复我

[dou23]

补充一下，记得把libcore下的build.sh代码修改一下，以免提示-cache或者-trimpath找不到 把下面这段代码注释

gomobile bind -v -androidapi 21 -cache $(realpath $BUILD) -trimpath -ldflags='-s -w' -tags='with_conntrack,with_gvisor,with_quic,with_wireguard,with_utls,with_clash_api,with_ech' . || exit 1

修改为 gomobile bind -v -androidapi 21 -tags='with_conntrack,with_gvisor,with_quic,with_wireguard,with_utls,with_clash_api,with_ech' . || exit 1

这边在win下编译到最后一步提示 C:\Go\bin\gomobile.exe: go build -tags with_conntrack,with_gvisor,with_quic,with_wireguard,with_utls,with_clash_api,with_ech -v -buildmode=c-shared -o=C:\Users\NICODE~1\AppData\Local\Temp\gomobile-work-3241027813\android\src\main\jniLibs\x86\libgojni.so ./gobind failed: exit status 1 build.sh已经修改。

[dou23]

你看看和项目同级的目录下，sing-box和libneko这两个库有拉下来吗 @NicodeLee

[NicodeLee]

@dou23 没有下到sing-box和libneko这两个库 更前面的提示信息是这样：

[maskedeken]

Go版本太旧了

[NicodeLee]

那更新一下go，这还是上次编译frpc的时候弄完就好久没用了

[NicodeLee]

可以了，感谢 @dou23  @maskedeken  。Android home路径还要点问题这个换下就好了。

[NicodeLee]

aar现在编译有70m不知道你们打吧是怎样优化apk体积的 @dou23 @maskedeken
