如何为Android构建命令行应用程序？

I want to build small app for android that I can run from the android command line while I'm remotely connected to the android device through ssh. I don't want a button/launcher/icon or gui interface of any kind.

I prefer to do this in golang if possible.

I tried using gomobile (golang.org/x/mobile) but when I put the apk on my device and try to run it I get the error:

u0_a44@ghost:/data/data/berserker.android.apps.sshdroid/home $ am start gserv.apk                                         
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] pkg=gserv.apk }
java.lang.SecurityException: Permission Denial: startActivity asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

    at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method)
    at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:249)

The app is just a small hello world http server. How can I install and run it in a way that allows me to use it like other command line programs built into android that don't require gui (ls, cat, cd, etc).

Appears to vary by system and version, but I needed to get the android ndk from here:

https://developer.android.com/ndk/downloads/index.html

and install the toolchain

./android-ndk-r10c/build/tools/make-standalone-toolchain.sh --platform=android-21 --install-dir=$NDK_ROOT

and then build the binary with

CC="$NDK_ROOT/bin/arm-linux-androideabi-gcc" GOOS=linux GOARCH=arm GOARM=7 CGO_ENABLED=0 go build -v -o goserv main.go

I got most of this info from here: https://github.com/golang/go/issues/9412

But needed to change change some paths, change CC_FOR_TARGET to just CC, GOOS=android to GOOS=linux, and needed to set CGO_ENABLED=0.

This was on Linux Fedora 25 Beta with Go 1.7.4
