我下载了android-ndk-r12b-linux-x86_64.zip,将对应的文件拷贝到pkg/gomobile/android-ndk-r12对应目录下，可以正常编译。

谢谢！That led me to the fix that appears to be in progress:

CL https://golang.org/cl/24724 mentions this issue.

@axengine Hi, can you share what you exactly did for a workaround? I have tried downloading NDK r12b and put it in $GOPATH/pkg/gomobile as android-ndk-r12 but did not work.

[Hovelander]

Still getting "/pkg/gomobile/android-ndk-r12/arm/bin/arm-linux-androideabi-nm: no such file or directory" even after applying Elias' latest patches @ https://go-review.googlesource.com/#/c/24724/ locally. No "b" joy to be had.

Tried mucking about with the suggestions from @axengine & @hyangah, but no joy from my efforts there either (although take those efforts with a large, ham fisted flavor of newbie salt).

Guess I'll just turn my attention to the working iOS example until this is sorted and wait patiently for Elias to figure out the issue. (Good luck and thanks Elias & others!)

Sorry for the delay.
gomobile NDK release is blocked in some internal process.
The easiest workaround meanwhile is to roll back to d5b8fb1623bebcf0646aba78cfd8208159e1cc45 (https://go.googlesource.com/mobile/+/34d472ecb61e8fb5396dfa0b2bc3048e780f76d7)

I will update this bug once the NDK release is approved.

[hyangah]

they are uploaded.
@eliasnaur you can submit the cl.

[Hovelander]

Works as intended, thanks!

Great work 👍
