正在运行Android 10(API 29)。但我认为这个bug可能是因为我错误地使用了gomobile bind命令，或者是gomobile的bug。

在Corellium上的构建者正在运行Android 9,安装的NDK版本是23b。

在Corellium上的构建者正在运行Android 9,已安装的NDK版本是23b。请问我需要更换NDK版本吗？当前是21.4.7075529。

@cherrymui The builders on Corellium are running Android 9 and the installed NDK version is 23b.

Can you maybe provide a minimal example to show your build process? The previous description is not clear as the project that you claim to build is not clear to us too.

OK

1

download some repositories( GO111MODULE="on" )

go get -u github.com/anacrolix/torrent
go get -u github.com/dustin/go-humanize

2

here is my code(only 17 lines)

import (
	"fmt"
	"github.com/anacrolix/torrent"
	"github.com/dustin/go-humanize"
)

func GetBtInfo() {
	var t *torrent.Torrent
	cfg := torrent.NewDefaultClientConfig()
	cfg.DataDir = "./movie"
	c, err := torrent.NewClient(cfg)
	if err != nil {
		fmt.Printf("err: %v", err)
	}
	url := "magnet:?xt=urn:btih:38F07BE8BBBBE4F2C6CBEC909F5C7BFAB8114185&dn=Resident%20Evil%20Welcome%20to%20Raccoon%20City%202021%20x264%20AAC%20800MB%20SD%20HDC&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969%2Fannounce&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A6969%2Fannounce&tr=udp%3A%2F%2F9.rarbg.to%3A2710%2Fannounce&tr=udp%3A%2F%2F9.rarbg.me%3A2780%2Fannounce&tr=udp%3A%2F%2F9.rarbg.to%3A2730%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337&tr=http%3A%2F%2Fp4p.arenabg.com%3A1337%2Fannounce&tr=udp%3A%2F%2Ftracker.torrent.eu.org%3A451%2Fannounce&tr=udp%3A%2F%2Ftracker.tiny-vps.com%3A6969%2Fannounce&tr=udp%3A%2F%2Fopen.stealth.si%3A80%2Fannounce"
	t, err = c.AddMagnet(url)
	if err != nil {
		fmt.Printf("add err: %v", err)
	}
	<-t.GotInfo()
	size := humanize.Bytes(uint64(t.Info().TotalLength()))
	fmt.Printf("totalSize: %s, name: %s", size, t.Info().Name)
}

3

use gomobile

gomobile init   

 gomobile bind -v  -target=android ./android/

this step will output an .aar file(named android.aar )

4

copy the .aar file to Android studio, and implementation

implementation files('libs/android.aar')

5

create a buttun in my Android app, when click, call the android.aar method GetBtInfo

Android.getBtInfo();

6

build and run the Android project. the app run successfully. But when i click the buttun which call a method Android.getBtInfo(); , crashed. Here is the error log.

java.lang.UnsatisfiedLinkError: dlopen failed: library "libc++_shared.so" not found

我也遇到了这个问题。相同的复现。anacrolix/torrent(可能是anacrolix/go-libutp)的一个依赖项使用了C++。
